All You Need To Know About Biological Safety Cabinets (BSCs)




Designed for storing and protecting critical goods, biological safety cabinets (BSCs) are essential for preventing laboratory-acquired contamination of stocks, cultures, and specimens.

These cabinets contain an enclosed workspace, allowing users to conduct experiments without being exposed to hazardous substances. That's why these cabinets are a crucial element for aiding research and clinical labs across Australia. 


What Are The Different Types of Bio Safety Cabinets? 

Since the requirement of every industry is not the same, the biosafety cabinet comes in three classes, each having its distinct characteristics. Read on to know more about them. 


1. Biosafety Cabinet Class I

The class I cabinets are basic units capable of providing the environment, product, and personal protection. These cabinets are primarily meant for laboratories handling biological agents with moderate to low risk. The experiments on these agents are often performed in open labs without the need for specialized contaminant equipment. 


2. Biosafety Cabinet Class II 

As compared to Class I, the biosafety cabinet class II is a ventilated unit that mostly manages infectious substances such as tissue culture. Further, the class II cabinets come in A1, A2, B1 & B2 variants, each having a varied ratio of exhausting air and recirculating air into the cabinet. 


3. Biosafety Cabinet Class III 

The Class II safety cabinet is 100% enclosed. The specimen gets tested under extreme pressure to ensure there is no leakage of particles into the laboratory environment. HEPA filtered air gets supplied into the unit, while the exhaust air passes from the unit through 2 HEPA filters.


The airflow to the cabinet remains consistent via an exterior exhaust system that keeps the workstation in negative pressure.


In these cabinets, the users can connect with a double-door autoclave for decontaminating materials. 


Whether you want to buy the finest safety cabinet or have an industry-specific requirement, a good practice is to count on a reliable manufacturer that provides superior quality cabinets.


The best part is that dependable companies even customize the size and features of the cabinets according to your requirements, helping you protect your products, environment, and resources.
