In the field of animal experiments, the purification degree of the experimental environment is directly related to the accuracy and reliability of experimental results. A clean and stable experimental environment can not only provide good living conditions for experimental animals but also help researchers obtain accurate and effective data. Guangzhou Cleanroom Construction Co., Ltd., a professional manufacturer in the purification equipment industry, hereby deeply analyzes how to accurately select purification equipment for animal laboratories.
I. In - depth Analysis of Laboratory Purification Requirements
Differences in Experimental Animal Categories
Different types of experimental animals have significantly different sensitivities to the environment. For example, small rodents such as mice and rats reproduce rapidly and have a relatively high breeding density. This requires the laboratory to be equipped with an efficient air purification system to quickly filter out pollutants such as exhaled waste gas, dander, and feed dust from the animals, and maintain good air quality and a suitable temperature and humidity environment. For primates, due to their large size, they produce more odors and pollutants during their activities. In addition to basic air purification, powerful deodorization equipment and efficient waste treatment systems are also needed to ensure the cleanliness of the experimental environment.
The Nature of Experiments Determines the Purification Level
If the laboratory is mainly engaged in infectious disease research, the biosafety requirements for purification equipment are extremely high. The equipment must be able to effectively filter and kill pathogens in the air to prevent the spread of viruses, bacteria and other microorganisms. Equipment such as HEPA filters with ultra - high filtration efficiency and hydrogen peroxide gas disinfectors that can perform thorough disinfection are indispensable. Conversely, for experiments that are extremely sensitive to environmental cleanliness, such as gene editing and high - end drug research and development, any tiny impurity may interfere with the experimental results. At this time, air purification and disinfection equipment with extremely high precision and stability are required to create an almost zero - pollution experimental environment.
II. A Comprehensive Understanding of Purification Equipment Types
Air Purification Equipment
- High - Efficiency Particulate Air (HEPA) Filter: As the core equipment for air purification, the HEPA filter can filter out particles in the air with a diameter greater than or equal to 0.3 microns, and its filtration efficiency is as high as over 99.97%. Whether it is a general environment facility or a stringent isolation environment facility, the HEPA filter is a key part in ensuring clean air.
- Activated Carbon Filter: It is mainly used to adsorb odors and harmful gases in the air, such as ammonia and hydrogen sulfide generated by experimental animals. In areas with a high breeding density, the activated carbon filter can significantly improve air quality and make the experimental environment more comfortable.
- Air Disinfection Equipment: Common ones include ultraviolet disinfection lamps and hydrogen peroxide vapor disinfectors. Ultraviolet disinfection lamps kill microorganisms in the air through ultraviolet irradiation, which is easy to operate and has a low cost; hydrogen peroxide vapor disinfectors can comprehensively and thoroughly disinfect the air and the surfaces of items in a specific closed space, and are often used in barrier environment and isolation environment facilities with extremely high hygiene requirements.
- Ventilation System: A good ventilation system is responsible for timely discharging the dirty air in the room and introducing purified fresh air to maintain the continuous circulation of indoor air. A reasonable design of the ventilation volume and air flow organization can effectively avoid air dead corners and reduce the risk of pollutant accumulation in the room.
Waste Treatment Equipment
- Experimental Animal Disinfection Transfer Cabinet: During the transfer of live animals and experimental instruments, the disinfection transfer cabinet plays an important role. It has ventilation and disinfection functions, which can not only ensure animal welfare but also prevent cross - contamination between different areas.
- Bedding Collection Station: When dumping the bedding in the cage box, the bedding collection station can prevent staff from inhaling dust and polluted exhaust gas, protect the health of the staff, and at the same time properly collect the bedding for subsequent unified treatment.
- High - Temperature Steam Sterilization Equipment: For example, a pulsating vacuum sterilizer can perform high - temperature and high - pressure sterilization treatment on animal feed, drinking water, cage boxes, and various breeding supplies, creating a sterile living environment for experimental animals and being widely used in various experimental animal breeding units.
III. Key Points for Accurate Selection
Matching Equipment According to the Purification Level
General environment facilities only need to be equipped with basic air filtration and ventilation equipment to meet basic purification needs. Barrier environment facilities require medium - and high - efficiency air filters, a stable ventilation system, and corresponding disinfection equipment to strictly control air cleanliness. Isolation environment facilities have the most stringent purification requirements and must use ultra - high - efficiency air filters and comprehensive disinfection and sterilization equipment to achieve an almost sterile experimental environment.
Pay Attention to Equipment Quality and Brand
Choosing purification equipment from well - known brands means that the stability, durability, and purification effect of the equipment are more guaranteed. Guangzhou Cleanroom Construction Co., Ltd. has been focusing on the research, development, and production of purification equipment for many years. Its products have undergone strict quality inspections, are made of high - quality materials, and have excellent performance, which can effectively reduce the failure rate of equipment and reduce subsequent maintenance costs and downtime.
Consider Operating and Maintenance Costs
In addition to the equipment procurement cost, operating energy consumption and maintenance costs are also important parts of long - term expenditures. When selecting equipment, energy - saving equipment should be given priority to reduce daily operating costs. At the same time, it is necessary to fully understand the maintenance difficulty of the equipment and the supply of spare parts, and choose equipment that is easy to maintain and has easily accessible spare parts. Guangzhou Cleanroom Construction Co., Ltd. provides a complete after - sales service system that can respond to customer needs in a timely manner and ensure the continuous and stable operation of the equipment.
Strictly Comply with Relevant Standards and Specifications
The construction of animal laboratories must comply with relevant national and industry standards, such as GB 14925 "Experimental Animal Environment and Facilities". When selecting purification equipment, it is necessary to ensure that the equipment meets these standard requirements to ensure the compliance operation of the laboratory.
Accurately selecting purification equipment for animal laboratories requires considering multiple factors.
