subject: Class Iii Biological Safety Cabinet Manufacturer In India [print this page] Biological Safety Cabinets (BSCs) are among the most effective and the most commonly used primary containment devices in laboratories working with infectious agents. Acmas technocracy BSC Class III provides operator and product protection for work with up to category 4 pathogens. With two high-efficiency particulate air (HEPA) filters at the exhaust point, a class III biological safety cabinet protects the user and the environment from the specimen under study. Cabinet is a totally enclosed ventilated cabinet of gas-tight construction. Operations within the Class III cabinet are conducted through attached rubber gloves. When in use, the Class III cabinet is maintained through negative air pressure of at least 0.5 inches water gauge. Supply air is drawn into the cabinet through HEPA filters. The cabinet exhaust air is filtered by two HEPA filters, installed in series, before discharge outside of the facility. The exhaust fan for the Class III cabinet is generally separate from the exhaust fans of the facility's ventilation system. It provides the highest level of
protection to the operator and the environment. Class III biological safety cabinets are gas-tight and designed for use with high risk microbiological agents and potent compounds.
The Class III Biological Safety Cabinet is a totally enclosed, ventilated cabinet of gas-tight construction and offers the highest degree of personnel and environmental protection from infectious aerosols, as well as protection of research materials from microbiological contaminants. Class III cabinets are most suitable for work with hazardous agents that require Biosafety Level 3 or 4 containment. All operations in the work area of the cabinet are performed through attached arm length rubber gloves or half-suits. The Class III cabinet is operated under negative pressure. Supply air is HEPA-filtered and the cabinet exhaust air is filtered through two HEPA filters in series, or HEPA filtration followed by incineration, before discharge outside of the facility.Weiber high performance Class III Biological Safety Cabinet is suitable for work with high-risk biological agents like those belonging to hazard group 3 and 4. A class III Biological Safety Cabinet should not be used alone, but should incorporate the necessary equipment and be sited in specially designed laboratory facilities for handling high-risk samples (i.e. containment level 3 or 4). Several Class III cabinets can be joined together in a custom-built manner to provide a larger work area. A class III cabinet in basic laboratory should not be used to handle high risk samples.
