Air filters for scientific research
Laboratories used for research in microbiology, biomedicine, biochemistry, animal experiments, genetic recombination and biological products are collectively called clean laboratories, also known as biosafety laboratories. Biosafety laboratories are composed of main functional laboratories, other laboratories and auxiliary functional rooms. Biosafety laboratories must ensure personal safety, environmental safety, waste safety and sample safety, and can operate safely for a long time, while also providing a comfortable and good working environment for laboratory staff.
The air conditioning system is the key to the safe operation of clean laboratories. It must be operated through reasonable design to maintain the relative negative pressure environment of the clean laboratory, and it must not be destroyed at any time to ensure that dangerous microorganisms in the laboratory cannot spread to the external environment. At the same time, it must also control the cleanliness of the laboratory, filter the fresh air, and make the laboratory meet certain purification requirements. Among them, the exhaust system is the focus, which plays an important role in ensuring the relative negative pressure environment of the laboratory and effectively filtering the indoor polluted exhaust.
Air filters play an indispensable role in the ventilation system of microbiological laboratories. They are installed at key locations such as the air inlet, exhaust outlet or inside ventilation equipment of the ventilation system. Their main purpose is to remove various pollutants such as particulate matter and harmful gases in the air. In the special environment of microbiological laboratories, filters are responsible for filtering out microbial particles in the air to prevent the growth and spread of microorganisms in the ventilation system, avoid the spread of microorganisms caused by ventilation, cause cross-contamination within the laboratory and potential threats to the external environment.
According to the standards of filtering effect and the size of particles that can be intercepted, common filters can be divided into primary filters, medium efficiency filters and high efficiency filters. The primary filter is mainly responsible for filtering out relatively large particles, such as dust and fluff, and plays a role in preliminary air purification; the medium-efficiency filter has a higher filtration accuracy, mainly capturing dust particles of 1-5 microns, and can further intercept smaller particles and some microorganisms. It is divided into plate filters and bag filters. The high-efficiency filter has excellent filtration capacity and can efficiently filter out extremely small particles and microorganisms, ensuring that the air discharged from the ventilation system meets strict environmental protection standards and maximizes the safety of air quality inside and outside the laboratory.
Trenntech’s air filtration products cover the primary, medium and high-efficiency filtration levels commonly used in laboratories, and can provide higher-level sterile filter elements for laboratories or medical systems, providing researchers with a good working environment and experimental conditions.
