Biological Safety Cabinet Type III

At the forefront of life science and medical research, biological safety cabinets shine with their excellent performance and key role.

In terms of appearance design, biological safety cabinets show professionalism and rigor. The cabinet body is made of thick steel plate material, which is finely processed and polished. It not only has strong pressure resistance, but also can effectively resist the erosion of chemical substances. The cabinet surface is smooth and flat, without any gaps and dead corners, which is convenient for thorough cleaning and disinfection, and eliminates the space for microorganisms to hide and reproduce. The transparent protective window is made of high-strength, UV-proof glass material, which not only provides a clear operating field for experimenters, but also effectively blocks the influence of harmful light on experimental samples.

The working principle of the biological safety cabinet is like a set of sophisticated air purification symphony. First, after the external air is inhaled, it passes through the primary filter to initially filter out large particles of impurities such as hair and fiber in the air. Then, the air enters the composite filtration system composed of HEPA filter and activated carbon filter. The HEPA filter is like a fine sieve, which catches tiny biological particles such as bacteria, fungi, viruses and aerosols in the air, and its filtration accuracy can reach the nanometer level. The activated carbon filter is responsible for absorbing harmful chemical gases and odors in the air and further purifying the air. The air that has been purified layer by layer forms a stable laminar airflow in the cabinet, flowing vertically downward evenly from the top, passing through the operation area, and then discharged from the exhaust port at the bottom. This unique airflow circulation mode ensures that any biohazardous substances that may be produced during the experiment are firmly confined in the cabinet and cannot spread to the external environment.

In terms of function, the biosafety cabinet has many highlights. It is equipped with an intelligent control system that can automatically monitor and adjust parameters such as wind speed, temperature, and humidity to ensure that the equipment is always in the best working condition. At the same time, it also has fault diagnosis and alarm functions. Once the equipment has abnormal conditions, such as filter blockage, fan failure, etc., it will immediately send out sound and light alarm signals to remind staff to deal with it in time. In addition, the biosafety cabinet is also designed with a unique splash plate and waste liquid collection device to effectively prevent liquid splashing during the experiment from polluting personnel and the environment, and facilitate the collection and treatment of experimental waste liquid.

In many application scenarios, biosafety cabinets play a vital role. In microbiological laboratories, it is a safe haven for studying various pathogenic microorganisms, allowing researchers to safely conduct experiments such as bacterial culture and virus isolation; in the production workshops of biopharmaceutical companies, it ensures the safety of microbial testing and aseptic operation during drug production, ensuring the quality and safety of each batch of drugs; in the pathology and laboratory departments of hospitals, it provides a safe environment for the detection and analysis of clinical samples, avoiding cross-contamination between samples and potential harm to medical staff.

With its all-round safety protection functions and advanced technical design, the biological safety cabinet has become the mainstay in the field of biological experimental safety, laying a solid foundation for the smooth development of life science research and medical practice, and is a loyal guardian of human health and scientific exploration.
