Class I and II Type A2 Biological Safety Cabinets

Home / Products / Class I and II Type A2 Biological Safety Cabinets

They are utilised by a range of scientific and research facilities within the commercial and non-commercial sectors, including clinical research, defence, education and general healthcare sectors.

Biosafety cabinets are divided into three classes: I, II and III.


Class I provides protection for the user and surrounding environment, but no protection for the sample being manipulated.

Class II provides protection for the user, environment and sample, and is divided into four types: A1, A2, B1 and B2. The main differences are their minimum inflow velocities and exhaust systems.

Class III, also known as glove boxes, provides maximum protection; the enclosure is gas-tight, and all materials enter and leave through a dunk tank or double-door autoclave.

Choice of cabinet depends on level of protection needed for the laboratory worker and the sample of interest.

Our Core Services


Biological Safety Cabinets offer protection from microbiological contamination to the operator, environment and product. They are utilised by a range of scientific and research facilities within the commercial and non-commercial sectors, including clinical research, defence, education and general healthcare sectors.


Having the correct laminar air flow equipment in your cleanroom environment is very important, so British Clinical Services have worked hard to amass a quality selection of high-end equipment manufacturers for your needs.


Ductless fume hoods do not require any external ventilation. Instead, they use filters to capture solvent fumes from circulating air, which is then vented into the room. Ductless fume cabinets can maintain the same airflow as a standard vented fume hood but are easier to install as they do not require ventilation ducts.


Contamination control and PCR process repeatability is simplified with a range of PCR Cabinets. Each PCR Cabinet we install provides filtered vertical laminar flow to purge the work area of contaminants between amplifications and during preparatory procedures.


All fume cupboards and ventilated enclosures should be monitored and serviced annually both for safety and compliance purposes but also to retain the efficiency of your units.

British Clinical Services offer comprehensive maintenance and servicing agreement for all makes and models of Fume Cupboards.
