Laboratory Biosafety Cabinet

Years of understanding of this domain, has helped us in presenting the finest quality of Laboratory Biosafety Cabinet. For the purpose of protection from harmful agents inside the cabinet the laboratory biosafety cabinet is used. Known for its easy installation, compact design and enhanced functional life, the laboratory biosafety cabinets are fabricated by using modern machinery.

Features :

• Avoid contamination of the work and experiment
• Environmental protection from contaminants contained within the cabinet
• Easy installation

How Biological Safety Cabinets Are Classified?

Classification is an important consideration in the selection of any biological safety cabinet

Over the years, the scientific community has adopted commonly accepted classification criteria to differentiate containment capabilities and performance attributes

Biological safety cabinets are divided into three classifications

Class I - Personnel and Environmental Protection Only:

The Class I biological safety cabinet is designed to provide personnel and environmental protection only

A Class I cabinet does not protect the product from contamination because dirty room air constantly enters the cabinet front to flow across the work surface

As a partial containment unit, the Class I cabinet is suitable for work involving low to moderate risk agents (bio safety levels 1, 2 and 3) where there is a need for containment, but not for product protection

Unlike conventional fume hoods, the HEPA filter in the Class I cabinet protects the environment by filtering air before it is exhausted

Personnel protection is made possible by constant movement of air into the cabinet and away from the user

Class II - Product, Personnel and Environmental Protection:

A Class II cabinet must meet requirements for the protection of product, personnel and the environment

This type of cabinet is widely used in clinical, hospital, life science, research and pharmaceutical laboratories

In general, cabinets are classified according to the method by which air volumes are recirculated or exhausted

The Class II biological safety cabinet has three key features

A front access opening with carefully maintained inward airflow

HEPA-filtered, vertical, unidirectional airflow within the work area

HEPA-filtered exhaust air to the room or exhaust to a facility exhaust system

Vertical, unidirectional airflow and a front access opening are common to most Class II cabinets

But, because Class II designs permit different airflow patterns, velocities, HEPA air filter position, ventilation rates and exhaust methods

Classification :

Cabinets previously classified as Class II, Type A/B3 are now classified as Class II, Type A2

These bio safety cabinets may be exhausted to the room, or connected to a facility exhaust system via a "canopy" connection (NSF recommends a canopy connection for cabinets exhausted to the outdoors)

The Class II, Type B3 classification no longer exists for new units

It is important to understand differences in cabinet Type in order to select the proper cabinet for your application

Note: All Madhav biological safety cabinets provide containment and protection from airborne particulates for personnel, the work area, and the environment
