Biosafety Cabinets Introduction

A biological safety cabinet (BSC) is a device that protects and ensures the safety of people by controlling the flow of contaminated air coming out of the cabinet as the first barrier to keep the operator and the surrounding environment away from infection.

Biological safety cabinets can be divided into 3 levels: Class I, Class II and Class III. In which the most common type is Class II, A2: 30% discharge, 70% recirculation.

Working principle

Protect the user against sources of infection, protect the surrounding environment but do not protect the specimen.

Biological safety cabinet – Class 2

Protect the user, the specimen, and the surrounding environment.

Biological safety cabinet – Class 3

Used in the laboratory with the highest level of toxicity, short blocking the most dangerous infectious agents to the outside.
