Air Purification and Filtration in Animal Laboratories: Guarding the Pure Line of Defense for Scientific Research

In the field of animal experiments, every subtle environmental factor can have a profound impact on the experimental results. Today, as Guangzhou Cleanroom Construction Co., Ltd., a manufacturer specializing in the production of purification equipment, we will delve into the crucial aspect of air purification and filtration in animal laboratories, revealing the importance and technical secrets behind it for you.

The immune systems of experimental animals are relatively fragile, and poor air quality can easily trigger various diseases. Microorganisms in the air, such as bacteria, viruses, and fungal spores, once inhaled by animals, may lead to respiratory infections, pneumonia, and other diseases, affecting the normal physiological functions of animals and the accuracy of experimental data. For example, in the experiment of gene-edited mice, if there are miscellaneous bacteria in the air, it may infect the mice and interfere with the experimental results related to gene expression, causing months of research efforts to go to waste.

Experiments in animal laboratories often have extremely high requirements for the environment, and even minor fluctuations in air quality can interfere with the experimental process. Dust particles in the air may carry impurities and contaminate experimental samples, leading to cell contamination in cell culture experiments and causing deviations in experimental data. In drug research and development experiments, animals inhaling unclean air may affect the drug metabolism process, mislead the evaluation of drug efficacy, and in severe cases, may even lead to the wrong research and development direction.

With the continuous improvement of requirements for the welfare of experimental animals and the quality of experiments, strict regulations and industry standards have been formulated both at home and abroad to standardize the environment of animal laboratories. For example, the national standard "Experimental Animal Environment and Facilities" in China clearly stipulates the air cleanliness and other indicators of animal laboratories at different levels. Failing to meet these standards may not only result in the experimental results not being recognized but also may face legal risks.

Bacteria are one of the common microbial pollutants in animal laboratories, such as Staphylococcus and Escherichia coli. They widely exist in the environment and can enter the laboratory through the entry and exit of personnel, items, and the ventilation system. Viruses are also dangerous. For example, the murine hepatitis virus can spread rapidly among animal populations, causing large-scale epidemics. Fungal spores cannot be ignored either. They have strong vitality and can multiply in large numbers under suitable conditions, polluting the laboratory air.

Particulate matter in the air includes dust, pollen, hair, etc. These particulate matters not only affect the air cleanliness but may also serve as carriers of microorganisms, increasing the risk of pollution. In animal laboratories, the activities of animals will stir up a large amount of hair and dander. If not filtered in a timely manner, they will suspend in the air, interfering with experimental operations and posing a threat to the health of animals.

The metabolism of animals will produce harmful gases such as ammonia and hydrogen sulfide. If these gases accumulate in the laboratory, they will not only have a pungent odor but also irritate the respiratory tract of animals, affecting the health of animals and the experimental results. In addition, the organic waste gases volatilized from some chemical reagents used in the laboratory, such as formaldehyde and benzene, also pose a hazard to the experimental environment and the health of personnel.

The high-efficiency air filter (HEPA) developed by our company adopts special filter materials and structural designs, which can effectively filter more than 99.97% of particulate matter with a particle size of 0.3 microns and smaller in the air, including microorganisms and dust particles. Installing our HEPA filter in the ventilation system of the animal laboratory can ensure that the air entering the laboratory reaches an extremely high cleanliness standard, providing a clean breathing environment for experimental animals.

For harmful gas pollution, we are equipped with an activated carbon adsorption device. Activated carbon has a huge specific surface area and a rich microporous structure, which can efficiently adsorb harmful gases such as ammonia, hydrogen sulfide, and formaldehyde. Combining the activated carbon adsorption device with the ventilation system can promptly remove the peculiar smell and harmful gases in the animal laboratory and keep the air fresh.

The intelligent ventilation control system of Guangzhou Cleanroom Construction Co., Ltd. can automatically adjust the ventilation volume and the number of air changes according to the real-time air quality data of the laboratory. Through sensors installed in different positions of the laboratory, parameters such as temperature, humidity, and air quality are monitored in real-time. The system automatically starts or turns off the purification equipment according to the preset thresholds, ensuring that the laboratory is always in the best air environment state while achieving energy conservation and consumption reduction.

Air purification and filtration in animal laboratories are the cornerstone of the success of scientific research. With professional technology and high-quality products, Guangzhou Cleanroom Construction Co., Ltd. is committed to creating a pure and safe experimental environment for animals.
