【Chemical machinery and equipment network industry news】Biological safety cabin.
BSC) is a box-type air purification negative pressure safety device
that can prevent aerosol dissipation of certain dangerous or unknown biological particles during experimental operation.
According to the NSF49 standard, biosafety cabinets are divided into I.
, II.
, III.
class, which can be applied to the operation
of different biosafety level media.

Biosafety cabinet is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, biological products and other fields, and is the most basic safety protection equipment in the first-level protective barrier of laboratory biosecurity, and is an important foundation
for ensuring the safety of operators.

At present, for biological safety cabinets in China, there are two industry standards, such as pharmaceutical industry standards YY0569-2011 "Class II Biological Safety Cabinet" and JG170-2005 "Biological Safety Cabinet", and the two industry standards have been implemented for many years, and there are shortcomings
such as overlapping scope, duplicate content, lagging technical indicators and test methods, and product technology development.

On October 12, 2022, the national standard "GB 41918-2022 biological safety cabinet" was released, which specified the requirements for terms and definitions, classification, materials, structure and properties, test methods, markings, labels, instructions, packaging, transportation and storage of biological safety
cabinets.

The main contents are as follows:

1 Scope This standard specifies the terms and definitions, classification, materials, structural and performance requirements, test methods, markings, instructions, packaging, transportation and storage requirements for biological safety cabinets
.
This standard applies to biological safety cabinets (hereinafter referred to as safety cabinets).
