Biosafety Cabinet is an enclosed and ventilated laboratory for safely working with materials contaminated with pathogens requiring a defined biosafety levels. They are used by various scientific and non-scientific organizations like pharmaceutical, medical, clinical research, defense and general healthcare. The biosafety cabinet guard users, materials and the environment from aerosol hazards and other kinds of environmental contamination.
Biosafety cabinets provide:
- separating tools for biomedical study
- security devices for biological risk prevention
- Laboratory tools work testing
- work-related hygiene and security
- Ecological hygiene
- Disease cleansing and avoidance
They are generally used in biotechnology, pharmaceutical and clinical laboratory processes.
Choosing a Biosafety Cabinet
There are a number of biosafety cabinet manufacturers, which provides you the equipments for specific lab processes and conditions. The market is filled with different kinds of Biosafety Cabinets that has been categorized into classes – I, II, III. All safety cabinets are provided with the exact requirements of the laboratory. This is recommended for the best practice.
In this case, seek advice of experience people who have knowledge regarding this cabinet or who are engage in the production of biosafety cabinets, bio-technology and clean air products.
Biosafety Cabinet Classes
There are 3 kinds of biological cabinets such as – Class 1, Class 2 and Class 3. These cabinets are divided by purposes and structure.
Class 1 Biosafety Cabinet
A biosafety cabinet with a working front opening through which a user can perform work inside the cabinet, offers operator protection through inward airflow allowing the runaway of airborne elements produced within the cabinet with the support of HEPA filtration of the tire out air. This kind of cabinet is perfect for all kinds of biological works. Class 1 Biosafety cabinet designed to provide protection to the user.
Class 2 Biosafety Cabinet
A class 2 Biosafety cabinet provides protection for both worker and materials from the dangerous micro-biological agents. It is designed to balance airborne contamination of the work and decrease risks of exposure of the operator to any airborne particles dispersed within the cabinet from the work process. The process is balanced by re-circulating filer air over the work area mixed with inflow air passed through the working aperture. The runaway of airborne particles produced within the cabinet is balanced by inner airflow, which is clean prior to flow within it, well the down flow clean air over the working surface to create a safe work environment.
Class 3 Biosafety Cabinet
A class biosafety cabinet provides complete safety for the operator and is perfect for bio-work. Inflow air is filtered prior to deliver the cabinet through a side fixed inlet filter chamber. Exhaust air is filtered prior to delivering the safety cabinet through an individual filter layer, depends on the customer’s specific requirements. Here are some included features to make you understand easily –
- Complete enclosure of the work place
- User divided from the work by a barrier
- Clean air constantly supplied to the cabinet
- Exhaust air treated to stop infectivity
- Gives complete safety for user and materials
Work in the class 3 biosafety cabinet are performed through the gloves mechanically fixed to the cabinet offering a complete seal against any specific contamination released within the main working place. Only class 3 cabinets are completely enclosed parts, which are suitable for work.
These biosafety cabinets work very efficiently and can perform tasks under high-pressure. The cabinets are available in the market at very reasonable rates, analyze your requirements first and get it.
