Download Brochure

Biosafety Cabinets are specialized workstations widely used in clinical, pharmaceutical, life science and industrial laboratories where experiments need highly contaminant free environment. Also known as biological safety cabinets and biohazard safety cabinets, these are made in three different class types such as Class 1, Class 2 and Class 3; in which Class 2 is widely used in microbiology laboratories because it provides protection to both product as well as personal. It is biosafety level factor which decides which BSC should be used in laboratory.  These  cabinets  are  considered  safer  than  other   clean   benches   because  such BSCs effectively eliminate risks to operator / staff, samples and the environment from pathogenic biological agents (PBA) and microorganisms responsible for spreading airborne infection.

  • Features and Benefits


    There are three types of class 2 biosafety cabinets are made. It is the type of work which decides which class 2 BSC should be used in laboratory. Below is short description about all types:

    • Type A2: recirculate approximately 70% air and 30% exhaust
    • Type B1: recirculate approximately 30% air and 70% exhaust
    • Type B2: Does not recirculate but exhaust 100% air


    These cabinets are ergonomically designed to provide long service life. Only thick metal sheets and pipes are used in construction so that you may get the finest and safest Biosafety Cabinet in the market today. There are three different MOC used.

    • Complete Stainless Steel 304 / 316
    • Inner Stainless Steel, Outer Mild Steel
    • Stainless Steel bench, rest mild Steel

    Air Circulation:

    In order to minimize spread of airborne bacterial and viral organisms, the use of filter is crucial; therefore, we use 99.97% efficiency HEPA filters for particle size 0.3 microns in our biological class 2 type A2 safety cabinets. These air filters are of reputed brands in the market, economical in price and easy replaceable. ISO 5 / Class 100 quality, supply and exhaust through HEPA filters are done. Inflow velocity remains approx. 105 fpm (0.5 m/sec), while down flow velocity remains approx. 55 fpm (0.3 m/sec). 70 % air is re-circulated and 30% exhaust.

    Standard Accessories:

    Our Biosafety cabinets are fitted with fluorescent lights outside working zone. UV lamps are fitted inside working zone in such a way that the operator cannot see them directly. An hour meter is connected to UV lamp. Electrical sockets are fitted to run any instrument under the working area; in addition, service fixtures for air, gas, vacuum and water are fitted on demand. 

    We also manufacturer biosafety cabinets class 2 type B1 and B2.
