Biosafety Cabinets


Bio safety cabinets are available in the following models:
·         Bio Hazard Safety Cabinet Class - II Type A1, Type A2, Type B1, Type B2, Class – III.
Specification of Bio Safety Cabinet

Bio Safety Cabinet Class I
The class I bio safety cabinets is an open-front design and works on the principle of negative pressure generations.  The exhausted air is filtered through high efficiency particulate air filter (HEPA) filter.  This Class I bio safety cabinet is ideal to be used where the Personnel and environmental protection is key, but not product protection.

Bio Safety Cabinet Class II
This Class II vertical laminar-flow biological cabinet is an open-front, ventilated cabinet.  This cabinet provides a HEPA filtered, recirculated mass airflow within the work space.  The exhaust air from the cabinet is also filtered by HEPA filters.   This type of bio safety cabinets provides excellent protection to users, products and the environment. While HEPA filters are effective for trapping particulates and infectious agents, these filters will not capture volatile chemicals or gases.

Bio safety Cabinet Class III
Bio safety cabinet class III is a totally closed compact and purely ventilated enclosure having an air tight construction.  All the experiments/procedures are performed through rubber gloves, which are provided at the front of the unit. The primary feature of class III bio safety cabinets is that they maintain negative pressure of 0.5” or more while in operation. The supplies of fresh air are taken inside the enclosure through specially designed high efficiency perfect air filters (HEPA). The exhausted air of the unit is passed through two modules of HEPA filters, which are strategically placed in series. The air passes through the two filters before being discharged in the environment. The exhaust fan for the Class III cabinet is generally separate from the exhaust fans of the facility’s ventilation system.  These types of bio safety cabinet have complete self sustained exhaust system.
