Bio Safety Cabinet

Product Details:

WEIBER Biological Safety Cabinet are widely used for day to day clean room activities involving high risk pathogens, etiological agents, nonvolatile radio nuclides and limited degree of low toxic chemicals for various applications in research labs of all the branches of medical, agriculture, basic and applied science.

 

We specialize in both standard and customized models of Biosafety Cabinet specially designed to meet the challenging demands of various scientists for individual and specialized research applications. The equipment has microprocessor based controllers with digital display of all key parameters. The floor standing & portable cabinet provides access for passage of materials inside through a double door pass through box.

 

The Biosafety Cabinet Class I have an open front design and works on the principle of negative pressure generation. The exhausted air is filtered through high efficiency perfect air filter before disbursing in the environment. This Biological Safety Cabinet Class I is ideal to be used where user protection and environmental protection is key but does not provide product protection.

Product Details:

WEIBER Biological Safety Cabinet Class II is an open-front, ventilated cabinet. This cabinet provides a HEPA/ULPA-filtered, recirculated mass airflow within the work space. The exhaust air from the cabinet is also filtered by HEPA/ULPA filters. Thus, the Class II biosafety cabinet will provide personnel, environment and product protection. While HEPA/ULPA filters are effective for trapping particulates and infectious agents, these filters will not capture volatile chemicals or gases

 

The use of a Biological Safety Cabinet Class 2 in the microbiological laboratory offers the additional capability and advantage of protecting materials contained within it from extraneous airborne contaminants. This capability is provided by the HEPA-filtered, recirculated mass airflow within the workspace.

 

It is suitable for the containment of biohazardous materials and unlike the Class I biosafety cabinet, it is also suitable as a sterile environment for cell cultures.

 

Classifications:

It is classified in 4 categories:

Class II, type A1: this does not have to be vented, which makes it suitable for use in laboratory rooms which cannot be ducted. This cabinet is acceptable for use of low to moderate risk agents in the absence of volatile toxic chemicals and volatile radionuclides.

Type A, has a minimum inflow velocity of 75 ft/min. The filtered makeup air is divided equally over the work surface at about two to six inches above the work surface. Exhaust is drawn at the bottom of the cabinet where it rises to the top. At the top of the cabinet, 70% of the air recirculates through the supply HEPA filter, the other 30% of air exhausted through the exhaust HEPA/ULPA filter.

This type is not safe for work with hazardous chemicals except when ducted, usually with a "thimble" or canopy hood to avoid disturbing internal air flow.

Class II, type A2: this must be vented. 70% of the air is exhausted from the cabinet while 30% is recirculated. This cabinet may be used with etiologic agents treated with minute quantities of toxic chemicals and trace quantities of radionuclides that will not interfere with work if recirculated in the down flow air.

The Type A2 cabinet, has a minimum inflow velocity of 100 ft/min. A negative air pressure plenum surrounds all contaminated plenums that are under positive pressure. In other respects, the specifications are identical to those of a Type A1 cabinet.

Class II, type B1: this cabinet must be vented, with 30% of the air exhausted from the cabinet while 70% is recirculated back into the room. This cabinet may be used with etiologic agents treated with minute quantities of toxic chemicals and trace amounts of radionuclides required as an adjunct to microbiological studies if work is done in the directly exhausted portion of the cabinet, or if the chemicals or radionuclides will not interfere with the work when recirculated in the down flow air.

The Type B1 cabinets have a minimum inflow velocity of 100 ft/min

Class II, type B2: this cabinet must be totally exhausted, with100% of the air exhausted through a dedicated duct. This cabinet may be used with etiologic agents treated with toxic chemicals and radionuclides required as an adjunct to microbiological studies.
The Type B1 cabinets have a minimum inflow velocity of 100 ft/min.

Product Details:

WEIBER Biological Safety Cabinet Class III are among the most effective and most commonly used primary containment devices in laboratories working with infectious agents. They act as primary barriers to prevent the escape of biological aerosols into the laboratory environment. The Biological Safety Cabinet Class 3, generally only installed in maximum containment laboratories, is specifically designed for work with pathogenic agents, providing maximum protection. The enclosure is gas-tight Gloves attached to the front prevent direct contact with hazardous materials (Cabinet Class III are sometimes called glove box). These custom-built cabinets often attach into a line, and the lab equipment installed inside is usually custom-built as well.

The BioSafety Cabinet Class III is a totally enclosed ventilated cabinet of gas-tight construction. Operations within the Class III cabinet are conducted through attached rubber gloves. When in use, the Class III cabinet is maintained through negative air pressure of at least 0.5 inches water gauge. Supply air is drawn into the cabinet through HEPA filters. The cabinet exhaust air is filtered by two HEPA filters, installed in series, before discharge outside of the facility. The exhaust fan for the Class III cabinet is generally separate from the exhaust fans of the facility's ventilation system.
