Bio safety cabinet is designed to provide both a clean work environment and protection to operators who work with biological hazards. It has vertrical laminar airflow to create a barrier to airborne particles and micro organisms. High Efficiency Particulate Air (HEPA) filters are used to provide clean air in the work area as well as to the environment through exhaust the HEPA filter. The air in the cabinet is re-circulated over the work area through the HEPA filter.
BIOSAFETY CABINETS are classified into three categories: Class I, Class II, Class III.
Class I: The class I Biological Safety Cabinet is an open front negative pressure cabinet. The exhaust air from the cabinet is filtered by a high-efficiency particulate air (HEPA) filter. It provides protection to human beings and environment only. Class I cabinets suitable for work shere no product protection is required.
Class II: The Class II vertical laminar-flow biological cabinet is an open-front, ventilated cabinet. This cabinet provides a HEPA-filtered re circulated mass airflow within the workspace. The exhaust air from the cabinet is also filtered by HEPA filter. Thus, Class II bio safety cabinet provides protection to product as well as to human beings and environment. While HEPA filters are effective for trapping particulates and infectious agents, it is suitable for the containment of bio hazardous material thereby providing sterile environment for cell culture. Class II cabinet is most versatile and economical model.
