Biosafety cabinets made by the best biological safety cabinet manufacturers are a ventilated and enclosed workspace that can handle all the potential and dangerous biological materials. The biological safety cabinets with the Air washer system offer protection for the environment, the user and the product by filtering and controlling the contaminants and airflow.
There are research tools, safety features and lighting along with these cabinets to provide a safe and sterile working space to the users. With time, technology is evolving, and so are the designs of the biosafety cabinets with improved efficiency and safety.
What are the Different types of cabinets by the biological safety cabinet manufacturers?
There are primarily three varieties of biological safety cabinets available in the niche market.
- Class I
This type of safety cabinet has a fundamental and simple design. It offers protection to the working surroundings and the operation manager by trapping the airflow inward along with aerosols produced during the microbiological experiments. The trapped air then moves through the filtration system containing the HEPA and pre-filter. These filters eliminate all the contaminants and airborne particles before going out of the system.
- Class II
Class II cabinets with an Air washer system are capable of handling different pathological applications or samples that need a complete sterile environment. The inflow air trapping feature prevents any exposure to harmful materials. HEPA or ULPA filter pressurizes the air downflow to stop any cross-contamination, maintaining an ISO class 3 standard clean working spaces and making sure to control the sample integrity.
The exhaust protects the atmosphere by filtering the air that will be released outside. Biological safety cabinet manufacturers produce three types of Class II cabinets, as below.
- Type A
It recirculates 70% of the air and exhausts 30%. It is accurate for the users who need containment of BSL-1, 2, or 3 types.
- Type B1
The common plenums present in Class II type B1 cabinets can exhaust 70% of the air and recirculate 30% of it. It is ideal for users who have to handle volatile, dangerous chemicals in small quantities.
- Type B2
The biological safety cabinet manufacturers call this type of cabinet the total exhaust, as 100% of the air gets recirculated.
- Class III
This type of cabinet with an Air washer system offers the highest containment level, which is impossible with class I and II ones. However, they are the most expensive ones, offering complete protection to the sample and user. These cabinets are gas-tight and are composed of welded metal with glove ports to handle all the materials. HEPA filters exhaust the air and help to maintain negative pressure for additional containment safety.
There is a pass-through unit for safer material transfer. The biological safety cabinet manufacturers have designed Class III cabinets in such a way that the exhausted air goes out to the outside surrounding through a committed duct system, making it perfect for any microbiological work.
Advantages of Using Improved Biosafety Cabinets with Modern Technologies
Biological safety cabinets offer complete protection to the laboratory users through improved protection against chemical and biological hazards. It offers increased cost savings and energy efficiency through decreased maintenance and power consumption charges.
It has a lower environmental impact through efficient filtration systems and air flow. Bilogical safety cabinets offer enhanced productivity and laboratory efficiency through automatic sash positioning and user-friendly controls.
FAQ
What are the restrictions in the conventional cabinets?
Traditional biosafety cabinets by the top biological safety cabinet manufacturers offer restricted protection against potential chemical hazards. They have a high noise level and power consumption. The cabinets also have decreased air circulation and deliver contaminated recirculation of the air. The users face immense difficulty in the decontamination and cleaning of the cabinets. The filter replacement and manual sash positioning procedure is quite complex, resulting in an increased threat of direct exposure.
Conclusion
Biosafety cabinets with an Air washer system have already improved their efficiency and laboratory safety with various innovative technologies. By considering the difficulties and advantages of conventional cabinets by the renowned biological safety cabinet manufacturers, users can select only the best technologies according to their work and laboratory. There is a bright and shining future for the biological safety cabinets with the promise of providing more secure and efficient working spaces.
