Benchtop Biosafety Cabinet

What is Biological Safety Cabinet BSC (Biosafety Cabinet)?

Devices that provide the environment needed when biological pollutants are released and / or sensitive work away from the effects of biological pollutants are called biological safety cabinets or biosafety cabinets. Contaminating particles often cause respiratory damage. Biological agents, that can hang in the air with the inhaled air, can spread to the human body by entering the lungs and from there into the bloodstream. In order to identify and prevent risks that may occur before or after working in the environment, or to minimize the likelihood of occurrence, safe working conditions for human health should be provided based on scientific methods. Sterile Cabinet is a device that enables all kinds of work done with biological agents (sowing, analysis, experiment etc.) in laboratory environments safely. Accumax India designs and manufactures biosafety cabinets in various models for a better working environment.

Types of Biosafety Cabinets

  1. Class I BSC: Provides personnel and environmental protection but not product protection.
  2. Class II BSC: Provides personnel, environmental, and product protection. These are the most commonly used in labs handling hazardous or infectious materials.
    • Type A1: Suitable for work with agents that require Biosafety Level 1, 2, or 3 containment.
    • Type A2: Similar to Type A1 but has a greater level of protection and is more commonly used.
    • Type B1 and B2: Suitable for work with low to moderate risk biological agents and hazardous chemicals.
  3. Class III BSC: Also known as glove boxes, these provide the highest level of protection and are used for high-risk biological agents.

Key Features

  • Airflow System: Ensures that air moves in a way that protects the user and the environment from exposure to hazardous agents.
  • HEPA Filters: High-Efficiency Particulate Air filters trap airborne contaminants and ensure that the air inside the cabinet is clean.
  • UV Light: Some cabinets have UV lights for sterilization purposes, but these should be used with caution and according to manufacturer guidelines.


  • Microbiology: Working with bacteria, viruses, fungi, and other microorganisms.
  • Cell Culture: Protecting cell cultures from contamination.
  • Pharmaceuticals: Ensuring a sterile environment for drug preparation and testing.
  • Clinical Testing: Handling patient samples that may contain infectious agents.

Safety and Maintenance

  • Certification: BSCs should be certified annually by a qualified technician to ensure they are working correctly.
  • Proper Use: Users should be trained in proper techniques to prevent contamination and exposure.
  • Cleaning: Regular cleaning and decontamination are essential to maintain the safety and efficacy of the BSC.

How to Use Biological Safety Cabinet?

The Biosafety safety cabinet should be placed indoors where the traffic is the least, away from air conditioning systems, doors and windows. The biosafety cabinet should be made of water, moisture and chemical resistant material. The air extraction system in the biosafety cabinet must be capable of providing continuous airflow and can operate 24 hours a day. Electrical installations and equipment and mechanical installations and equipment must be isolated from each other. Electrical outlets and switches must be protected. Burners and heaters that can generate excessive heat can damage HEPA filters, so their use in the biosafety cabinet should be taken into consideration and Bunsen burners should not be opened too close to the filters. Preventing materials should not be in front of the suction grilles. Air suction and outlet grilles should  always be open. Security measures should be taken before working in the biosafety cabinet.
The cause of human error is often lack of information and carelessness. Despite all the precautions taken, an accident that may occur in the working environment should be taken into consideration and a first aid team should be available in the institution.
