Learning Nuances of Biosafety Cabinets for Multiple Uses

In laboratories and specific educational setups, dealing with hazardous microorganism and pathogens becomes necessary. So, adopting safety measures and devices to contain contamination becomesmandatory. This is where Biosafety Cabinets come into the picture. The units are used extensively in such setups to minimize risk of infection. They are available in various types nowadays.

In several clinical and educational setups, students, professors and scientists need to deal with potentially hazardous microorganisms. These include various types of bacteria, viruses and pathogens. It becomes necessary to deal with these hazards for teaching, demonstration, scientific research etc. To ensure the microorganisms do not get spread though air or other means, specific devices have to be used. That is why doctors, researchers and staffs in similar setups make use of Biosafety Cabinets. They came into vogue in the 1950s.

The ideal way to keep bio hazards contained
Biohazards need to be contained properly, whether it is in laboratory of a college or a clinical research institute. The usage of Biosafety Cabinets has become popular in these setups over the years. When apt precautions are taken and safety measures are adopted, these cabinets play a pivotal role in keeping biohazard contained. Generally, these cabinets are equipped with HEPA filters which are also fitted in Fume hoods. These cabinets are also used to keep contents sterilized.

The available options
There are broadly 3 kinds of Biosafety Cabinets and each offers a specific level of protection against biological hazards. The main purpose of using these units is safeguarding laboratory workers as well as the environment from hazardous biological organisms. The air within these cabinets is made to go through a HEPA filter when exiting and thus microorganisms are removed. However, these devices are not the same as laminar flow clean benches. Fume hoods cannot offer the environmental protection offered by a top notch cabinet.
The CDC has segregated these cabinets into 3 main types.
Class I cabinets give environmental and personnel protection but they should not be used for product protection. These devices are mostly linked to the building’s exhaust system.
In Class II cabinets, both the environment and contents can be safeguarded against pathogens. There are 4 sub segments- A1, B1, A2 and B2. Each type is made to comply with NSF global standards. In these cabinets, a top mounted fan draws sterile air atop the products. The air is then made to pass through the work surface. Then it passes through top mounted HEPA filters.
Class III cabinets are used largely in laboratories dealing with highly contagious bio hazards. The enclosure is mostly gas-tight and materials are entered by a double-door autoclave or dunk tank.
Buying the right device
Buying the right type of Fume hoods and cabinets to contain microorganism may not be an easy task. You have to think of aspects like work needs, ergonomics and available space at your setup. Modern cabinets also have noise reduction mechanisms deployed.

There are quite a few companies that manufacture such products and sell them online. If you want a reliable solution, try the products from MoonMed see website at: www.moonmed.com.
