Biological Safety Cabinet
The primary purpose of a biosafety cabinet (BSC or Biological Safety Cabinet or Microbiological Safety Cabinet) is to protect the laboratory users and the environment from pathogens. BSC provides for an enclosed and ventilated workspace. The enclosed space enhances safety when working with materials contaminated (or potentially contaminated) with pathogens. Biosafety cabinets find use where a defined biosafety level is required.
Kewaunee’s Class II biosafety cabinets provide protection of the samples and of the environment, since makeup air is also HEPA-filtered. Class II biosafety cabinets are characterized by a limited fixed inward airflow access opening providing personnel protection, a vertical downward HEPA filtered work zone offering product protection and HEPA filtered exhaust providing environmental protection.
How does a Biosafety Cabinet Class 2 work?
A biological safety cabinet Class 2 is specifically designed to safeguard laboratory personnel, the environment, and the products from hazardous biological materials. It operates on the principle of inward airflow combined with HEPA filtration to create a safe working environment. When in use, air enters through a fixed opening at the front of the unit, trapping contaminants inside the cabinet. This air is then passed through a HEPA filter, which effectively removes 99.97% of particles, including pathogens.
In a biosafety cabinet class 2, the same air is drawn downwards into the work zone, providing a protective barrier that safeguards samples from contamination. Additionally, the exhaust air is HEPA-filtered before being released into the atmosphere, ensuring environmental safety. This design makes the biosafety cabinet class 2 essential for applications such as microbiology and clinical research.
7 Essential Features of Biological Safety Cabinet Class 2
- HEPA Filtration: Filters air to capture 99.97% of airborne particles, including pathogens, ensuring a clean environment.
- Downward Airflow: Draws air in from the front and flows it downward, creating a barrier that protects samples and personnel.
- Exhaust Filtration: Filters exhaust air through HEPA before it’s released, keeping the surrounding area safe.
- User-Friendly Controls: Easy-to-use touch-screen control panels, allowing for quick adjustments and monitoring.
- Ergonomic Design: Designed for comfort with features like armrests and ample workspace, making it easy to work for long periods.
- Integrated Lighting: Built-in LED lights provide clear visibility, helping users see their work without extra lighting.
- Durable Construction: Made from high-quality, easy-to-clean materials, ensuring long-lasting use in labs.
These essential features make the biological safety cabinet Class 2 a crucial tool for any laboratory handling biological materials, ensuring safety and performance.
