Different Classes of Biosafety Cabinets: An Informative Guide

Biosafety Cabinet Manufacturers - It becomes a matter of utmost concern when scientists and researchers deal with harmful germs, toxic chemicals, or other dangerous materials. Biosafety cabinets (BSCs) are the answer to such scenarios. These specialized workspaces are designed to provide three levels of protection: to keep the person using the cabinet safe, ensure the work being done is not contaminated, and prevent harmful substances from entering the environment.

Biosafety cabinets, in labs dealing with highly sensitive or hazardous materials, are very crucial. They play the role of a physical barrier to ensure that not even a dangerous particle nor microbe reaches the user nor the surroundings.

In the following blog, we're going to break down all you need to know concerning biosafety cabinets, its types, and usage.


What Are Biosafety Cabinets?

Biosafety cabinets are equivalent to protective workspaces applied in laboratories. They're similar to big boxes with glass panels, where scientists could conduct their work with poisonous materials without fear of getting diseased or contaminating them.

These cabinets do three primary things:

  • • Protect People: Prevent harmful germs or chemicals from leaking out and infecting or poisoning the cabinet user.
  • • Clean Environment: They maintain the work environment clean, so the germs or dust cannot destroy the products or the research.
  • • Protect the Environment: They prevent harmful substances from being let out and harming the outside world.


1. Class I Biosafety Cabinets

Class I biosafety cabinets are the most primitive among all, primarily designed to guard the user and the ambient environment against harmful particles or fumes. It provides no sterility to the workspace itself. They ensure that no harmful particle finds its way into the lab by pulling air from a front opening. They make sure that the dangerous material is removed from it using filters before releasing into the atmosphere. Class I cabinets are used for low-risk chemicals, dust, or simple laboratory work with non-hazardous or low-risk germs. They are effective and simple in ensuring basic safety in lab environments.

2. Class II Biosafety Cabinets

Class II biosafety cabinets are the most commonly used cabinets in laboratories. They offer protection to the user, the workspace, and the environment. Such cabinets are particularly important for tasks that must be performed in sterile conditions, like experiments with germs or pharmaceutical manufacturing. These cabinets have high-efficiency filters that clean the air both entering and exiting the workspace, thus preventing harmful particles from contaminating the lab or the materials that are being handled. Air flow is carefully controlled so that cross-contamination does not occur, and the front opening can be used for work without exposure to harmful substances. Class II cabinets exist in subcategories A1, A2, B1, and B2, which are determined by the airflow patterns and methods of filtration, thus versatile in most applications of laboratories.

3. Class III Biosafety Cabinets

Class III biosafety cabinets are the safest available, for use with the most virulent germs or dangerous chemicals. All such cabinets are totally enclosed and sealed, so access to the workspace is open; instead, air passes through double filtration systems, eliminating all risk of harmful substance exposure. Users interact with the materials in the cabinet by wearing gloves attached to the structure and thus not having direct contact. Class III cabinets are used where there is an extreme infectious agent, like in biowarfare studies or experiments of high danger, to provide maximum protection for both the user and the environment.


How to Choose the Appropriate Biosafety Cabinet for You?

Depending upon the kind of job you are doing, decide which is suitable for you.

  • • General Experiments: For nonpathogenic germs or dust, a Class I cabinet is enough.
  • • Advanced Research: For sterile environments or work with dangerous germs, go for Class II.
  • • Very High-Risk Work: For deadly germs and chemicals, you need the top-level protection of Class III.

 

Consider your needs then talk to a trusted Biosafety Cabinet Manufacturers in order to make an appropriate choice.
