Biological Safety Cabinet (Class II) (SMT-BF-300)
This apparatus is designed to provide a safe, enclosed, and ventilated workspace for handling materials contaminated with pathogens, ensuring protection for the user, the laboratory environment, and the research product itself. It is used to maintain a sterile field and contain biohazards during microbiological or cell culture work that requires a defined biosafety level.
The cabinet is a Class II type, featuring a front opening with a two-layer toughened glass window and an airflow system that recirculates 70% of the air through HEPA filters while exhausting the remaining 30%. It maintains specific inflow and downflow velocities to create a barrier against contaminants. The interior work surface is made of 304 stainless steel for easy decontamination, and the unit includes integrated utilities such as a UV lamp, fluorescent lighting, and waterproof electrical sockets, all controlled by a microprocessor-based system.
Its primary applications are in clinical, pharmaceutical, and biomedical research laboratories for procedures involving infectious agents or sensitive cell lines. The key benefit is the multi-level protection it offers; it prevents the release of aerosols into the lab, shields the user from exposure, and protects the samples from external contamination, thereby ensuring compliance with strict biosafety protocols and enabling safe handling of hazardous biological materials.
