Biological Safety Cabinets

Biological Safety Cabinets are safety equipments to be used for handling Hazardous Pathogens. These cabinets, apart fromcreating a Clean & Sterile environment, toprotect the product/sample also protects the Lab personnel and the Atmosphere.

The vertical downward airflow protects the product, the inflow along the front edge protects the user and the HEPA filtered exhaust air protects the atmosphere. We are looking for inqueries from South India & Overseas Countries.

Pathogens have been classified into four risk levels from 1 to 4. Based on the level of risk of the pathogenand the procedure, NSF-49 of USA has classifiedtheBiosafety cabinets into three Classes viz. Class I, Class II & Class III.

Class II cabinets are further classified into 3 typesviz. Type A/B3, B1 & B2.

Class II Type A/B3 recirculates 70% airand exhausts 30% air
Class II Type B1 recirculates 30% airand exhausts 70% air
Class II Type B2 exhausts 100% air without recirculation.

The cabinets is warranted for 12months excluding consumable parts and accessories.
Additional IQ/OQ documentation is available upon request.

Optional Items: Virus Burnout Unit or Second stage of Exhaust HEPA filter

Note 1: When air is exhaust from the Biosafety Cabinet, not only pathogens but air conditioned air is also thrown out. To compensate for the air lost, air has to be introduced into the room using Positive Pressure / Fresh Air Modules, to avoid leakage into the room through door opeingins / gaps. If fresh air is not fed from an air conditioned room, the lab is heated up to cool this additional Air conditioners have to be installed. As a thumb rule for every 200cfm of fresh air added one ton of AC should be added. For eg. for a 3' Type B2 cabinet, minimum of 2TR AC should be added.

Note 2: For a 3ft Biosafety Cabinet the exhaust air quantity is 450cfm, to heat this air even to to 80degC, 15kW of heater is required, which is too high considering power situation in India. To avoid this we have developed an alternative system that is being used in USA and Europe, which is an additional stage of HEPA filtration in exhaust. An additional HEPA filter Module with a blower and HEPA filter will be connected to the exhaust system. It may be noted that all the HEPA filters in the Biosafety cabinet have to be tested for Integrity using Aerosol Photometer after Installation at Site to ensure safety of the environment.

Class III Bio-Safety Cabinets

Approx. Price: Rs 1 Lakh / Piece(s) Onwards
Recommended for Product, Personnel & Environment protection only Air Balancing: 100% exhaust with incineration & working zone under negative pressure. As the power consumption for incineration is high (around 10kW), we suggest 2-stage exhaust filtration through HEPA/ULPA.

bioMARK-III, Class III Biological Safety Cabinet is designed for work with Microbiological agents assigned to biosafety level 4, and provides maximum protection to the environment and the worker. Access for passage of materials into the cabinet is through a double-door pass-through box that can be decontaminated between uses. Both supply and exhaust air are HEPA filtered. The exhaust air passes through two stage HEPA Filters, or a HEPA filtered and an air incinerator, before discharge to the outdoors. Airflow is maintained by a dedicated independent exhaust blower outside the cabinet, which keeps the cabinet safe, i.e. under negative pressure.
Arm-length, heavy-duty rubber gloves are attached in a gas-tight manner to ports in the cabinet and allow for manipulation of the materials isolated inside. Although these gloves restrict movement, they prevent the users direct contact with the hazardous materials.

Standard Features :
  • Exhaust air is double-filtered through high-quality HEPA/ULPA filters (per IEST-RP-CC-001.3) with typical efficiency of >99.999% for 0.1 to 0.3 micron particles
  • Exclusive dual exhaust filters provide >100,000 times better protection than single-stage designs.
  • Magnehelic pressure gauge* is mounted in the rear of the work zone for at-a-glance monitoring of work zone negative pressure.
  • Neoprene gauntlets are single piece leak-tested glove assemblies which guarantee maximum protection.
  • An integrated pass-through with interlocking doors, permits materials transfer without risk of environmental contamination.
  • Available in GI powdercoated or SS304 construction with leak free welded-sealed joints.
  • An angled cabinet front ensures an ergonomic working posture.
  • Cabinet operates at negative pressure relative to the laboratory in order to prevent migration of pathogenic materials out of the work area.
  • All cabinets individually tested for important paramenters as per NSF-49 with capability to Calibrate on Site after installation or periodically.
  • Calibrated Test Instruments used with traceability to NABL or (Inter)National Standards.

Class I Bio-Safety Cabinets

Approx. Price: Rs 50,000 / Piece(s) Onwards

Mark Air Class I biohazard safety cabinet is maintained under negative pressure, ventilated cabinet usually operated with an open front. All of the air from the cabinet is exhausted through a HEPA either into the laboratory or to the out side. The Class I BSC is designed for general microbiological research with low-and moderate-risk agents, and is useful for containment of mixers, blenders, and other equipment. These cabinets are not appropriate for handling research materials that are vulnerable to airborne contamination, since the inward flow of unfiltered air from the laboratory can carry microbial contaminants into the cabinet.
