Product Description

Product Description

One of the most functional units of the life science laboratory: the biosafety cabinet (BSC). Laboratory hoods, biosafety cabinets and enclosures may look similar, but they are all very different in function and are each engineered for specific applications.
Biosafety cabinet BSC are designed to handle hazardous pathogenic materials, among other biohazards, and are used regularly in various types of laboratories ranging from basic research to high containment. Sometimes biosafety cabinets are simply referred to as tissue culture hoods, laminar flow hoods, or chemo hoods in a pharmacy. Every BSC is categorized by a specific biosafety class: Class I, Class II or Class III. Different types of BSC operate and the recommended practices for each type based on current safety standards.
Biosafety Cabinet Classes
1. Biosafety Cabinet Class I
2. Biosafety Cabinet Class II a. Type A1 /A2 /B1 / B2 /C1
3. Biosafety Cabinet Class III
BSC is classified by how the cabinet protects the user and their samples, and defines the processes and applications each cabinet is designed to handle. In certain cases, some BSC classes have subtypes Such as Type A, Type B, and Type C.
2. Biosafety Cabinet Class II
BSC-Class II cabinets provide both kinds of protection (of the samples and the environment) since makeup air is also HEPA-filtered.
The principle of operation of Class II cabinets involves a fan mounted in the top of the cabinet that draws a curtain of sterile air over the workstation where the biological products are being handled.
The air then moves underneath the work station and back up to the top of the cabinet before passing through the HEPA filters.
The exhaust that moves out of the facility consists of air being drawn into the front of the cabinet underneath the work surface.
The air drawn in acts as a barrier against the potentially contaminated air coming back out to the operator.
Class II BSCs are further divided into five types depending on the exhaust system and the mechanism of work (recirculation of the exhaust air); Type A1, Type A2, Type B1, Type B2, and Type C1.
Type A1

a. Type A1
The type A1 cabinets have a minimum inflow velocity of 75ft/min where the contaminated divided just above the work station and mixes with the inflow air.
The mixed air is then drawn through a duct network so that it reaches the back of the cabinet.
After this, air might be either recirculated after passing through the HEPA filters or exhausted out of the cabinet, also through a HEPA filter.
This type of cabinet is not as widely used as it is not safe to work with hazardous chemical substances.

Type A2

b. Type A2
The type A2 cabinets have a minimum inflow velocity of 100 ft/min.In Class II, Type A2 BSC air enters the chamber through the front aperture, which provides operator protection.The inflow air mixes with the downflow air (from the top of the cabinet)and enters the front intake grille and then passes over the workstation where the air splits.
Approximately 60% to 70% of the contaminated air is recycled and pushed back into the workstation in the chamber through the downflow HEPA filter, while the remaining 30% to 40% is exhausted through the exhaust HEPA filter.
Because of the chances of the release of hazardous chemicals into the environment, A2 type cabinets are also not extensively used.
 

Type B1 B2

c. Type B1
Type B1 cabinets divide the airflow so that the contaminated air is directed towards the exhaust system while the air between the operator and the workstation mixes with the inflow and is recirculated.
The exhaust air dispersed out of the facility should be passed through the HEPA filters to provide protection to the environment.
These cabinets have a dedicated duct system which allows the release of the contaminated air out of the facility.
In the case of Type B1 cabinets, 40% of the air is recirculated, whereas the remaining 60% is exhausted out of the facility.
d. Type B2
For a Type B2 BSC, Air is also drawn in from an opening at the top of the cabinet that supplies the downflow of air in the cabinet.The air then passes through a HEPA filter, where 100% of the air is exhausted through a dedicated duct system with an exhaust fan motor. The air moving out of the facility is thus sterilized before its release into the atmosphere.The advantage of this system is the removal of toxic vapors that are generated in the cabinet with no recirculation within the BSC.All of the contaminated airflow (100%) in a Type B2 cabinet is externally exhausted which means the air drawn into the cabinet is 100% exhausted into the atmosphere.

Type C1

Type C1 cabinets are similar to Type B cabinets in their working mechanism, but these are designed to reduce operating costs add flexibility to the laboratories.
These cabinets work by using the single-pass airflow system where the cabinets move the air by mixing it with the downflow air separated into columns for recirculation.
The air above the workstation is drawn with a second fan which moves the contaminated air out through the exhaust system with a HEPA filter.
In this way, the cabinets provide protection to the environment, the operator, and the workstation or the biological material.
Type C cabinets are different from Type A cabinets as they use a single-pass airflow mechanism where the air is not circulated.
These differ from Type B cabinets in that they don't require a dedicated ducted exhaust system, can work for an extended duration to increase operator protection in the case of exhaust failure, and can even run without the exhaust at all.

3. Biosafety Cabinet Class III

Class III cabinets are leak-tight, totally enclosed but ventilated cabinets, where all air that either enters or leaves through the facility pass through a HEPA filter.
The cabinets are provided with rubber gloves that are attached to the system to be used during operations in the cabinet. This is why these cabinets are also termed 'glove boxes'.
The cabinet even has a transfer chamber that facilitates the sterilization of materials before they leave the glove box.
Even though the gloves restrict the hand movement of the operator inside the cabinet, it prevents direct contact between the operator and the samples.
The exhaust air is treated with double HEPA filters or HEPA filters in combination with incineration.
These cabinets can be used for all four Biosafety levels (1, 2, 3, and 4). But these are the most important for the manipulation of biological materials in the Biosafety level 4.
These cabinets are mostly custom-built for specific laboratories with lab equipment built inside the chamber.
All of these structural and design features provide maximum protection to the operator, the environment, and the sample against the high-risk group 4 pathogenic organisms.
