Engineering of Animal Laboratories: Biosafety Cabinets - A Solid Line of Defense for Experimental Safety

In the special environment of animal laboratories, scientific research work faces many potential risks. From the leakage of infectious pathogens to the spread of harmful aerosols generated during experimental operations, they can all pose serious threats to the health of experimental personnel, the accuracy of experimental results, and the ecological environment. As a core equipment in the engineering of animal laboratories, biosafety cabinets provide effective solutions to address these risks. Guangzhou Cleanroom Construction Co., Ltd. has been deeply engaged in the purification equipment field for many years. The carefully crafted biosafety cabinets are escorting the safe conduct of animal experiments with their excellent performance.

Animal experiments often involve bioactive samples. Whether it is studying the impact of infectious pathogens on animals or conducting experimental operations such as gene editing, the bioaerosols generated during the experiment are extremely dangerous. These aerosols may carry pathogens such as viruses and bacteria. Once they leak into the laboratory environment, they can easily cause cross - infection, not only endangering the experimental personnel but also potentially contaminating the entire experimental facility, forcing the experiment to be interrupted or even leading to complete failure. Biosafety cabinets can effectively capture and control these harmful aerosols by constructing a relatively independent and safe operating space, providing a safe and reliable "shelter" for experimental operations.

The biosafety cabinets of Guangzhou Cleanroom Construction Co., Ltd. adopt advanced airflow control technology to ensure that the airflow in the cabinet is stable and meets safety standards. Through a carefully designed fan system and airflow channels, a stable vertical unidirectional airflow is formed in the operating area, effectively isolating the operator from the experimental object. At the same time, the ingenious air intake design can ensure the smooth entry of external air and avoid the escape of harmful aerosols due to airflow disturbances. For example, in experiments dealing with highly pathogenic animal pathogens, this precise airflow control can ensure that the pathogens are firmly confined within the safety cabinet, greatly reducing the risk of leakage.

The filtration system is one of the core components of the biosafety cabinet. The biosafety cabinets of Guangzhou Cleanroom Construction Co., Ltd. are equipped with multi - layer high - efficiency filters, which can deeply purify the air entering and leaving the cabinet. The primary filter is responsible for intercepting large - particle dust and impurities, the medium - efficiency filter further removes smaller particles, and the high - efficiency particulate air (HEPA) filter can capture particles as small as 0.3 microns and above, with a filtration efficiency of over 99.99% for bacteria, viruses, and other microorganisms. This progressive filtration mechanism is like installing a tight "air filter" for the laboratory, ensuring that the discharged air is clean and harmless and preventing cross - contamination of indoor and outdoor air in the laboratory.

While pursuing high performance, the biosafety cabinets of Guangzhou Cleanroom Construction Co., Ltd. pay attention to humanized design. The spacious and bright operating area provides sufficient space for experimental personnel to carry out complex experimental operations. The operating tabletop is made of corrosion - resistant and easy - to - clean materials, which is convenient for cleaning and disinfection after the experiment. In addition, the equipped intelligent control system can real - time monitor parameters such as airflow, temperature, and humidity in the cabinet and present them to the operator through an intuitive display screen. Once an abnormal situation occurs, the system will immediately issue an alarm to remind the operator to handle it in a timely manner, ensuring the safety of the experiment.

In response to the diverse needs of animal laboratories, Guangzhou Cleanroom Construction Co., Ltd. has launched various types of biosafety cabinets. Type A1 biosafety cabinets are suitable for general animal experimental operations. They adopt a partial recirculation air design, which can not only meet the air quality requirements of experimental operations but also have good energy - saving effects. Type A2 biosafety cabinets optimize the air circulation and filtration systems on the basis of Type A1 and can be used to handle experimental samples with certain biological hazards. For high - risk animal experiments, such as research on highly pathogenic microorganisms, Type B2 fully exhausted biosafety cabinets are the best choice. They directly discharge all the air in the cabinet outdoors, ensuring that there are no pollutants remaining in the laboratory.

An animal laboratory of a well - known university used the Type B2 biosafety cabinet of Guangzhou Cleanroom Construction Co., Ltd. when conducting a study on the transmission mechanism of a new virus. During the entire experiment, the stable airflow control and high - efficiency filtration system of the safety cabinet ensured the cleanliness of the air in the laboratory and effectively prevented the leakage of virus aerosols. The experimental personnel reported that the operation process was safe and convenient, and the intelligent monitoring system gave them a sense of security. The person in charge of the laboratory said that the biosafety cabinet of Guangzhou Cleanroom Construction Co., Ltd. provided a solid guarantee for the smooth progress of the experiment and greatly improved the safety and reliability of the experiment.

The biosafety of animal laboratories is of utmost importance. As a key equipment to ensure safety, the performance of biosafety cabinets directly affects the success or failure of experiments. The biosafety cabinets of Guangzhou Cleanroom Construction Co., Ltd., with their advanced technology, excellent performance, and humanized design, have become the trusted choice of many animal laboratories.
