  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. Its unique multi-angle water spray design can generate a strong and uniform water flow, providing a 360-degree thorough rinse of the entire hand. 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.

  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. Pollutants in the air, such as dust and harmful gases, can affect the health of animals and, in turn, interfere with experimental results. High - Efficiency Particulate Air (HEPA) filters and Ultra - Low Penetration Air (ULPA) filters are core components of purification equipment for ensuring air quality. They can efficiently filter out tiny particles ≥0.3μm in the air, with a filtration efficiency of over 99.99%, effectively removing contaminants such as dust, bacteria, and viruses, thus creating a clean breathing environment for experimental animals. 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.
