Biosafety Cabinet Class I, II, and III

Biosafety Cabinet Class I, II, and III: A Complete Guide by Chameza Enterprises

When working in laboratories, safety is the top priority. Scientists and technicians deal with biological samples that may contain harmful pathogens, chemicals, or infectious agents. To ensure protection for both laboratory staff and the surrounding environment, biosafety cabinets are used. At Chameza Enterprises, we specialize in designing and providing high-quality biosafety cabinets that meet international safety standards. In this blog, we will explain the differences between Class I, II, and III biosafety cabinets in simple terms so you can choose the right solution for your lab.

What is a Biosafety Cabinet?

A biosafety cabinet (BSC) is a specially designed workspace that provides a controlled environment for handling hazardous biological materials. These cabinets use HEPA filters, controlled airflow, and containment systems to protect the operator, the sample, and the environment. Different classes of cabinets—Class I, II, and III—offer varying levels of safety and are used for different applications depending on the risk level of the work.

Class I Biosafety Cabinet

A Class I biosafety cabinet provides basic protection for the operator and the environment but does not protect the samples being handled. Air is drawn into the cabinet and filtered through a HEPA filter before being released outside. These cabinets are suitable for low to moderate-risk biological work.

• Protection level: Operator and environment (not the sample).

• Best use: For handling low-risk pathogens, small lab experiments, or educational labs.

• Advantage: Simple design and cost-effective solution.

At Chameza Enterprises, our Class I cabinets are built to international safety standards, ensuring reliable performance for labs across India.

Class II Biosafety Cabinet

The Class II biosafety cabinet is the most commonly used type in research and clinical laboratories. It provides protection to the operator, the environment, and the sample. Airflow is carefully maintained inside the cabinet with vertical laminar flow and HEPA filtration to prevent cross-contamination.

• Protection level: Operator, environment, and sample.

• Best use: Microbiology, molecular biology, tissue culture, and medical research labs.

• Advantage: Balanced protection and versatility for most laboratory needs.

At Chameza Enterprises, we offer Class II cabinets in different types (A2, B1, B2) to suit specific lab requirements. These cabinets are highly reliable for advanced laboratory setups.

Class III Biosafety Cabinet

A Class III biosafety cabinet offers the highest level of protection. It is also known as a “glove box cabinet” because the operator uses built-in gloves to handle materials inside the sealed cabinet. The entire system is gas-tight, and all exhaust air passes through HEPA filters, sometimes in multiple stages.

• Protection level: Maximum protection for operator, environment, and sample.

• Best use: Work involving dangerous pathogens like Ebola, SARS, or other high-risk infectious agents.

• Advantage: Complete containment for the most hazardous materials.

Chameza Enterprises manufactures Class III cabinets with advanced technology, ensuring absolute safety for high-risk laboratory environments.
