In the vast landscape of life science research, animal models have always been core elements for exploring metabolic processes, disease mechanisms, and therapeutic approaches. Metabolic cages for mice and rats, as key equipment in this field, hold immense significance. They create a near-natural living space for experimental animals, simulating their metabolic activities under normal physiological conditions, and continuously providing highly valuable research materials for scientists. I. Precise Monitoring of Energy Metabolism Energy metabolism monitoring is a critical function of mouse and rat metabolic cages. Equipped with highly accurate sensors or weighing systems, these sophisticated components act as dedicated recorders, real-time and meticulously tracking the food intake, drinking frequency, and total water consumption of mice. This function plays a vital role in multiple research directions. In studies on appetite regulation mechanisms, researchers can use this feature of metabolic cages to observe changes in feeding behavior under different stimuli, thereby deepening our understanding of the neural and endocrine pathways governing appetite. In research on the effects of nutritional interventions, take the high-fat diet model as an example: by accurately recording the food and water intake data of mice during the high-fat diet period, metabolic cages can intuitively assess the impact of high-fat diets on energy intake and metabolic balance, providing critical data support for research on obesity and related metabolic diseases. Additionally, in drug development, metabolic cages can be used to study the effects of drugs on feeding behavior and determine whether drugs have potential side effects on appetite.   Metabolic cages can also calculate the respiratory quotient (RQ) and energy expenditure through indirect calorimetry, which involves precisely measuring the oxygen consumption (VO₂) and carbon dioxide production (VCO₂) of mice. This technology is indispensable in the study of metabolic diseases such as obesity and diabetes. For instance, in obesity research, monitoring changes in VO₂ and VCO₂ in obese mouse models under different interventions can provide in-depth insights into the abnormal energy metabolism patterns of obese mice and the improvement effects of interventions on their energy expenditure and metabolic status, offering important evidence for the development of obesity treatment drugs and protocols. II. Sophisticated Excreta Analysis Analyzing the excreta of mice and rats is another core function of metabolic cages. Their specially designed cage bottoms act like intelligent sorters, skillfully separating urine and feces for collection, effectively avoiding cross-contamination and laying a foundation for subsequent precise analysis.   Urine analysis serves as a vital window into an animal’s physiological and metabolic status. By detecting electrolyte levels in urine, researchers can understand the ion balance within the animal’s body, which is crucial for studying kidney function, endocrine regulation, and certain electrolyte disorder-related diseases. For example, monitoring glucose levels in urine is a key indicator for determining the progression of diabetes and the effectiveness of treatments. Meanwhile, detecting hormones (such as corticosterone) in urine can reflect an animal’s stress level and endocrine status, aiding research on the pathogenesis of stress-related diseases. Furthermore, analyzing metabolic products (such as urea) or drug excretion in urine can provide important data for pharmacokinetic studies, helping to determine the metabolic pathways and excretion patterns of drugs in the body.   Fecal analysis also contains rich information. Studying gut microbiota metabolites can reveal the complex relationships between gut microbial communities and host health. For example, changes in certain gut microbiota metabolites are closely associated with the occurrence and development of diseases such as intestinal inflammation and metabolic syndrome. By analyzing these metabolites in feces, researchers can gain insights into the role of gut microbiota in disease mechanisms, providing a theoretical basis for developing gut microbiota-based therapies. Additionally, fecal analysis can be used to study food digestibility or intestinal absorption function. By detecting the proportion of undigested food components in feces, researchers can evaluate an animal’s digestive and absorptive capacity for different nutrients, offering important references for nutritional research.   Some advanced metabolic cages even have the function of collecting excreta in different time periods, which is like providing researchers with a "time microscope" to study the impact of circadian rhythms on metabolism. Many physiological processes, including metabolic activities, are regulated by circadian rhythms. By collecting excreta at different time periods and analyzing changes in metabolites, researchers can deeply understand how circadian rhythms affect an animal’s metabolic processes and the association between rhythm disorders and disease occurrence. III. Environmental and Behavioral Control Mouse and rat metabolic cages typically aim to create a stable and controllable environment for experimental animals. They can provide a constant temperature and humidity inside, ensuring the stability of environmental temperature and humidity during experiments and reducing the interference of environmental fluctuations on experimental results. At the same time, metabolic cages can precisely control light, simulating natural day-night light cycles, which is essential for studying the effects of light cycles on animal physiology and behavior. For example, in studies on circadian rhythm mechanisms, precise control of light conditions can help researchers explore the regulation of circadian gene expression and the resetting effect of light on the circadian clock.   Metabolic cages are also integrated with activity monitoring functions, commonly using infrared sensors or running wheels and other devices. These devices act as loyal observers, synchronously recording the activity levels of mice. By correlating metabolic data with behavioral changes, researchers can deeply study the impact of exercise on energy expenditure. For instance, in research on the mechanisms of exercise-induced weight loss, using metabolic cages to simultaneously monitor the exercise and energy metabolism parameters of mice can clearly reveal how exercise promotes energy consumption and regulates metabolic pathways, providing a theoretical basis for formulating scientific and reasonable exercise weight loss programs. IV. Diverse Application Scenarios Mouse and rat metabolic cages have extensive and in-depth applications in many research fields. In the study of metabolic diseases such as obesity, diabetes, and metabolic syndrome, they are indispensable tools. Through precise evaluation of energy metabolism abnormalities in mouse models, researchers can gain insights into disease pathogenesis, screen potential therapeutic targets, and evaluate the efficacy and safety of drugs and treatment protocols.   During drug development, metabolic cages play multiple important roles. They can be used to test the effects of drugs on metabolic rates, determining whether drugs can regulate the body’s energy metabolism, providing key data for developing drugs to treat metabolic diseases. At the same time, by monitoring the diuretic effects of drugs, researchers can evaluate the effects of drugs on kidney function, ensuring that drugs do not cause adverse effects on the kidneys while treating diseases. Additionally, metabolic cages can be used for drug toxicology and excretion studies. By analyzing the excretion pathways and metabolites of drugs in animals, researchers can assess the safety and potential toxicity of drugs.   However, when using mouse and rat metabolic cages for experiments, several issues need attention. Mice are highly sensitive to environmental changes and may experience stress reactions when entering the new environment of metabolic cages, which can interfere with metabolic data. Therefore, it is usually necessary to give mice a 1-2 day adaptation period to allow them to gradually become familiar with the new environment and reduce the impact of stress on experimental results. During this adaptation period, researchers need to closely observe the behavioral and physiological status of mice to ensure they adapt well, laying a foundation for the subsequent collection of accurate and reliable experimental data.   Metabolic cages for mice and rats, with their excellent functions in energy metabolism monitoring, excreta analysis, environmental and behavioral control, provide powerful and precise technical support for life science research. With the continuous advancement and innovation of technology, the performance and functions of metabolic cages will continue to be optimized and expanded, bringing more hope and possibilities for us to deeply explore the mysteries of life and overcome major disease challenges. Undoubtedly, they are a sharp sword in the journey of life science research, helping researchers continuously break into new research frontiers and achieve more groundbreaking scientific results.

  In the complex environment of animal laboratories, hand hygiene of personnel is often a crucial line of defense against cross-contamination, yet it is easily overlooked. During various operations such as handling experimental animals, operating equipment, and disposing of waste, laboratory personnel's hands will inevitably become contaminated with various microorganisms, residues of chemical reagents, and other pollutants. These contaminants not only pose a potential threat to the health of laboratory staff but also, through the movement and actions of personnel, act as "accomplices" of cross-contamination, interfering with the accuracy of experimental results. Sensitive to this pain point, Guangzhou Cleanroom Construction Co., Ltd. has launched the Hand Washing, Drying and Disinfection Machine for animal laboratories, providing a one-stop cleaning solution to build a solid barrier for laboratory safety and hygiene. Limitations of Traditional Handwashing and Disinfection Methods Traditional handwashing and disinfection in animal laboratories usually involve using a regular faucet with soap or hand sanitizer for cleaning, followed by drying with paper towels, and finally a simple wipe with alcohol wipes for disinfection. This approach has several drawbacks. Regular faucets have a single water outlet mode, and it is difficult to precisely control the water flow intensity and angle, making it hard to thoroughly clean the hands, especially areas such as finger crevices and under the nails. Paper towel drying not only leaves paper residue easily, increasing the burden of laboratory waste disposal, but also fails to effectively remove stubborn stains and kill microorganisms. Alcohol wipes have a limited disinfection range, unable to ensure comprehensive disinfection of the entire hand. Moreover, frequent use of alcohol may irritate the skin, reducing the comfort and work enthusiasm of laboratory personnel. Powerful Functions and Advantages of the Hand Washing, Drying and Disinfection Machine Efficient Cleaning with No Blind Spots The Hand Washing, Drying and Disinfection Machine by Guangzhou Cleanroom Construction Co., Ltd. is equipped with an intelligent sensor water outlet system. There is no need to manually touch the faucet, avoiding secondary contamination.

Whether it is the palm, back of the hand, finger crevices, or under the nails, every part can be fully cleaned, effectively removing all kinds of attached pollutants. At the same time, when paired with specialized laboratory-grade hand sanitizer, it can efficiently decompose and remove common residues of chemical reagents and microorganisms in experiments, ensuring that the hands are clean without any residue. Quick Drying for Convenience and Efficiency After cleaning, the built-in high-speed hot air drying system of the Hand Washing, Drying and Disinfection Machine starts immediately. The strong yet gentle hot air can completely dry the hands in a short time, eliminating the need for waiting and greatly improving work efficiency. Compared with traditional paper towel drying, hot air drying avoids problems such as paper residue and bacterial growth. It also reduces the use of paper towels, making it more environmentally friendly and cost-effective. Deep Disinfection for Safety and Reliability The disinfection process is one of the core advantages of the Hand Washing, Drying and Disinfection Machine. It adopts a dual disinfection technology combining ultraviolet light and ozone. Ultraviolet light can damage the DNA structure of microorganisms, rendering them unable to reproduce and survive. Ozone, with its strong oxidizing properties, can comprehensively kill remaining bacteria, viruses, and other pathogens. These two disinfection methods complement each other, enabling deep and thorough disinfection of the entire hand, with a disinfection rate of over 99.9%. This effectively reduces the risk of cross-contamination caused by pathogens carried on the hands, providing a solid safety guarantee for laboratory personnel and the experimental environment. Intelligent Integration for Easy Operation This Hand Washing, Drying and Disinfection Machine highly integrates the three major functions of cleaning, drying, and disinfection. It achieves one-click operation through an intelligent control system. Laboratory personnel only need to extend their hands into the sensing area, and the device will automatically complete the processes of water outlet for cleaning, hot air drying, and disinfection in sequence. The operation is simple and convenient, and no complex training is required to get started. In addition, the device is equipped with intelligent monitoring and fault warning functions.

  Cross-contamination is a very serious issue in animal laboratories. It not only interferes with the accuracy and reliability of experimental results but may even lead to experimental failures, severely hindering the progress of scientific research work. As a professional manufacturer in the field of purification equipment and cleanroom engineering, Guangzhou Cleanroom Construction Co., Ltd. will deeply analyze for you how to effectively reduce the risk of cross-contamination in animal laboratories with the help of purification equipment. Sources of Cross-Contamination in Animal Laboratories Airborne Transmission In animal laboratories, the breathing, excreta of experimental animals, and experimental operations can all cause a large number of microorganisms, dust particles, and odorous gases to suspend in the air. If the ventilation system cannot effectively filter and discharge these pollutants, they will circulate continuously indoors, thereby causing cross-contamination. For example, the air exhaled by an experimental animal infected with a specific pathogen may be inhaled by other healthy animals, resulting in the spread of the disease. Contamination Carried by Items All kinds of items entering the animal laboratory, such as feed, bedding, and experimental equipment, are likely to carry microorganisms into the laboratory if they are not strictly disinfected and sterilized. Moreover, during the experiment, if items from different areas are used interchangeably at will, it is also easy to cause cross-contamination. For instance, if used surgical instruments are used in other animal experiments without thorough disinfection, the pathogens on the previous animal may be transmitted to the next one. Personnel Movement Experimental personnel shuttling between different experimental areas may carry microorganisms on their clothes, shoes, and skin, thus introducing these microorganisms into different areas and causing cross-contamination. In addition, if personnel do not follow the correct operating procedures during the experimental operation, it may also lead to the spread of contamination. For example, if an experimental staff member enters the clean experimental area from the infectious experimental area without changing their work clothes, they may bring pathogens into the clean area. The Key Role of Purification Equipment in Reducing Cross-Contamination Air Purification Equipment High-Efficiency Particulate Air Filter (HEPA): It can filter out dust particles, bacteria, viruses, and other microorganisms larger than 0.3 microns in the air, with a filtration efficiency of over 99.97%. Installed in the ventilation system, it can effectively purify the air entering the laboratory, reduce the concentration of pollutants in the air, and decrease the risk of cross-contamination caused by airborne transmission. For example, installing a HEPA filter at the ventilation outlet of the experimental animal breeding area can ensure that the air entering the breeding area is clean and protect the experimental animals from external pathogens. Activated Carbon Filter: It can adsorb odorous gases and some harmful chemical substances in the air, improving the air quality in the laboratory. If the odor gases such as ammonia generated by animal excreta are not removed in time, it will not only affect the working environment of experimental personnel but may also have an adverse impact on the health of experimental animals. The activated carbon filter can effectively adsorb these odorous gases, creating a comfortable experimental environment. Air Disinfection Equipment: Such as ultraviolet disinfection lamps and hydrogen peroxide disinfectors. Ultraviolet disinfection lamps achieve the purpose of sterilization by irradiating ultraviolet rays to destroy the DNA structure of microorganisms; hydrogen peroxide disinfectors use the strong oxidizing property of hydrogen peroxide to kill microorganisms in the air. Disinfecting the laboratory air after the experiment or regularly can effectively reduce the microbial content in the air and prevent cross-contamination. Water Purification Equipment If the drinking water of experimental animals is contaminated, it will also become a source of cross-contamination. Water purification equipment can remove impurities, microorganisms, and harmful chemical substances in the water through multi-stage filtration and disinfection treatment, providing clean drinking water for experimental animals. For example, water purification equipment using reverse osmosis technology can effectively remove bacteria, viruses, heavy metal ions, etc. in the water, ensuring the safety of the drinking water for experimental animals. Surface Disinfection Equipment The surfaces of experimental benches, cages, equipment, etc. need to be disinfected regularly. Surface disinfection equipment such as disinfectant wipes and spray disinfectants can conveniently and quickly disinfect these surfaces, killing the possible existing microorganisms and preventing cross-contamination. In addition, there are specialized cage cleaning and disinfection equipment that can clean and disinfect cages with high temperature and high pressure to ensure the cleanliness and hygiene of the cages. Waste Treatment Equipment The waste generated in animal laboratories, such as animal carcasses, excreta, and discarded bedding, is extremely likely to cause the spread of pollution if not properly disposed of. Waste treatment equipment such as incinerators and autoclaves can harmlessly treat these wastes. Incinerators completely destroy the waste through high-temperature incineration; autoclaves use high temperature and high pressure to kill the microorganisms in the waste, reducing the risk of cross-contamination.

  In fields such as life science research, pharmaceutical development, and disease prevention and control, animal laboratories play a crucial role. To ensure the health of experimental animals and the accuracy of experimental data, strict compliance with industry standards serves as the cornerstone of animal laboratory operations. Guangzhou Cleanroom Construction Co., Ltd., deeply engaged in the field of purification equipment and cleanroom engineering, fully understands the significance of purification equipment in enabling animal laboratories to meet industry standards. Today, we will provide a detailed analysis of how purification equipment plays a key role. I. Ensuring Air Quality: Laying the Foundation for Compliance Experimental animals are extremely sensitive to air quality.

In addition, the ventilation system is also an important part of purification equipment. A reasonably designed ventilation system can control the direction of air flow and the number of air changes, ensuring the orderly flow of air in the laboratory and preventing cross - contamination between different areas. Take barrier - environment animal laboratories as an example. Through the rational organization of air supply, return air, and exhaust air, the laboratory can maintain a positive or negative pressure state, preventing external pollutants from entering or internal harmful gases from diffusing, and strictly meeting the air quality requirements specified in Laboratory Animals - Environment and Facilities (GB 14925 - 2010). II. Precise Temperature and Humidity Control: Meeting Environmental Standards Stable and suitable temperature and humidity are essential for the healthy growth of experimental animals and the smooth progress of experiments. Different types of experimental animals have varying requirements for temperature and humidity. For example, the suitable temperature for mice is 20 - 26°C, and the relative humidity is 40 - 70%; for dogs, the suitable temperature is 18 - 26°C, and the relative humidity is 40 - 70%. The temperature and humidity control system in purification equipment can monitor and precisely regulate the laboratory environment in real - time. Data is collected through temperature and humidity sensors, and combined with an intelligent control system, it automatically adjusts the cooling, heating, humidifying, and dehumidifying functions of the air - conditioning unit to maintain the temperature and humidity within the standard range. This not only helps reduce the stress response of experimental animals and ensures the stability of their physiological indicators but also meets the strict regulations of industry standards for the environmental conditions of animal laboratories, providing strong support for the reliability of experimental results. III. Microbial Protection: Reducing the Risk of Infection Microbial contamination poses a significant challenge to animal laboratories. Once cross - infection occurs, it can not only affect the health of experimental animals but also lead to the failure of the entire experiment. Purification equipment plays multiple roles in microbial protection. On the one hand, the high - efficiency air - filtration system can intercept microorganisms in the air, reducing their concentration in the laboratory. On the other hand, purification equipment can be used in conjunction with disinfection and sterilization devices. For example, ultraviolet disinfection lamps and ozone generators can regularly disinfect the laboratory air and object surfaces, killing residual bacteria, viruses, and other microorganisms. In addition, the application of laminar flow purification technology in animal laboratories creates a unidirectional parallel air flow, reducing the suspension and diffusion of microorganisms in the space, further reducing the risk of infection for experimental animals and ensuring that the microbial control in the laboratory meets relevant standard requirements. IV. Waste Disposal: Complying with Environmental Protection Regulations Animal laboratories generate various types of waste, including animal excreta, used bedding, and discarded experimental reagents. If not properly disposed of, it can not only pollute the environment but also spread diseases. The waste disposal system in purification equipment can safely and effectively handle these wastes. For example, bio - safety autoclaves can subject pathogen - containing waste to high - temperature and high - pressure sterilization treatment, making it harmless before discharge or disposal. There are also specialized waste gas treatment devices that can adsorb, neutralize, and otherwise treat harmful gases generated during the experimental process, ensuring that the discharged gases meet environmental protection standards, avoiding pollution to the surrounding environment, and practicing the industry's green and environmentally friendly principles.

  In modern laboratory projects, the breeding environment of experimental animals plays a crucial role in the accuracy and reliability of experimental results. With the continuous advancement of technology, intelligent animal breeding cage systems have emerged, bringing revolutionary changes to the breeding of laboratory animals. Guangzhou Cleanroom Construction Co., Ltd., as a professional manufacturer of purification equipment and cleanroom engineering, will introduce in detail the advantages and applications of intelligent animal breeding cage systems in laboratory projects. I. Introduction to Intelligent Animal Breeding Cage Systems Intelligent animal breeding cage systems, such as the Individual Ventilated Cage (IVC) system, are highly efficient animal breeding equipment featuring independent supply and exhaust ventilation design. It is mainly composed of an intelligent main unit, sealed cage boxes, and a ventilation cage rack. Its working principle is that air, after being filtered by primary and HEPA high-efficiency filters (with a filtration efficiency of ≥99.997%), supplies clean air independently to each cage box while exhausting waste gas independently, effectively preventing the spread of pathogens between cages. II. Demonstration of Core Advantages (I) Eliminating Cross - Infection and Ensuring Experimental Rigor Independent Ventilation Design: Each cage box has an independent supply and exhaust ventilation system, ensuring that the air in each cage box does not cross - contaminate with others. This greatly reduces the risk of pathogen transmission between animals in different cage boxes. For experiments with extremely high requirements for the health status of experimental animals, such as gene - edited mouse experiments and immunodeficient animal experiments, it can effectively ensure that experimental results are not interfered by external pathogens, making experimental data more accurate and reliable. Sealed Protection: The cage boxes adopt silicone gaskets and non - invasive docking structures, providing excellent airtightness. Additionally, the self - closing valve design further reduces the possibility of contamination during daily operations, such as changing bedding and adding food, providing a safe and clean living environment for experimental animals. (II) Energy Conservation and Cost Reduction Low Requirements for Room Environment: Compared with traditional barrier systems, intelligent animal breeding cage systems have lower dependence on the overall environment of the laboratory room. They do not need to maintain a high - cleanliness environment for the entire room like traditional systems, thus reducing the use of high - energy - consuming air - handling equipment. The operating costs can be reduced by more than 30%, significantly saving the laboratory's operating costs. Reduced Bedding Replacement Frequency: Through the design of low ammonia concentration and humidity inside the cages, the contamination rate of bedding can be effectively slowed down, thereby reducing the frequency of bedding replacement. This not only saves a large amount of bedding procurement costs but also reduces the workload of laboratory personnel for bedding replacement, improving work efficiency. (III) Double Improvement of Animal Welfare and Research Quality Low Noise and Vibration: The operating noise is ≤55dB (some advanced models are as low as 45dB), far lower than the national standard. The quiet environment can prevent animals from having stress reactions, keeping them in a more natural physiological state. For example, in some behavioral experiments, without noise interference, the behavior of animals can more accurately reflect the real situation, helping to improve the quality of research data. Constant Temperature and Pressure Environment: The system can precisely control the air velocity ≤0.2m/s, maintain stable pressure differences (0 - 20Pa), and keep suitable temperature and humidity inside the cages. A stable and suitable environment is conducive to ensuring the health of animals, keeping their physiological indicators relatively stable, providing a more reliable experimental model for scientific research, and enhancing the accuracy and reproducibility of research results. Intelligent Day - Night Mode: The main unit can automatically switch operating parameters according to the settings to simulate the natural light cycle. This is crucial for regulating the physiological rhythm of animals. For example, in research on the biological clock, a light cycle consistent with natural laws can make the physiological state of animals closer to the actual situation, avoiding deviations in experimental results caused by artificial light interference. (IV) Intelligent Management and Convenient Operation Touch - Screen Control and Remote Monitoring: The system is equipped with a liquid crystal screen that can display key parameters such as temperature, humidity, and pressure difference in real - time. Researchers can also remotely monitor and manage the system using mobile phones or computers through network connection. Once abnormal parameters occur, the mobile phone SMS alarm function will promptly notify relevant personnel, ensuring that problems can be addressed in a timely manner and maintaining the stability of the experimental animal breeding environment. Flexible Expandability: The cage racks support single - sided and double - sided configurations and can be flexibly adjusted according to the actual space size of the laboratory animal room and breeding scale requirements. Whether it is for the breeding of a small number of animals in a small - scale laboratory or large - scale animal experiments in a large - scale research institution, it is applicable. (V) Safe, Reliable, and Durable Materials High - Temperature and High - Pressure Resistant Cage Boxes: Cage boxes are usually made of materials such as PPSU and PEI, which can withstand sterilization at 134℃. This kind of material can not only effectively kill various pathogens, ensuring the hygiene and safety of the cage boxes, but also has high transparency, facilitating laboratory personnel to observe the status of animals at any time and promptly detect animal health problems or behavioral changes. 304 Stainless Steel Cage Racks: The cage racks are made of 304 stainless steel, which has excellent corrosion resistance and is easy to clean. Its sturdy and durable characteristics enable a service life of more than 10 years, reducing the frequency of equipment replacement and long - term use costs. III. Practical Application Cases Take the drug research and development laboratory of a large pharmaceutical company as an example. After introducing the intelligent animal breeding cage system, during the toxicity test experiments of new drugs, due to the independent ventilation and sealed protection design of the system, cross - infection between different experimental groups of animals was avoided. This ensured that the health status of each experimental animal was only affected by the drug factor, enabling the experimental data to more accurately reflect the toxic reactions of the drugs and providing a reliable basis for drug research and development. At the same time, the advantage of energy conservation and cost reduction also saved a large amount of operating costs for the laboratory. In addition, the intelligent day - night mode and good environmental control kept the experimental animals in the best physiological state, improving the success rate and reproducibility of the experiments. Another example is a life science research laboratory in a university. When breeding and conducting experiments on gene - edited mice, through the remote monitoring function of the intelligent animal breeding cage system, researchers can understand the breeding environment parameters of the mice at any time even when they are not in the laboratory and adjust the relevant settings in a timely manner. This has greatly improved the convenience of the experiments and management efficiency, ensuring the smooth progress of gene - edited mouse experiments. IV.
