NIKHTISH Bio- Safety cabinet
The term biological safety cabinet is used to describe a variety of containment devices equipped with HEPA filters, which are designed to provide personnel protection or both personnel and product protection from the hazards of handling infectious materials. The cabinets are defined by class and again by type based on their construction, airflow velocities and patterns, and their exhaust system.
The biological safety cabinet class I provides personnel and environmental protection, but no product protection. It has a limited fixed work access opening and the exhaust air is HEPA filtered, to protect the environment. The biosafety cabinet class I is designed for general microbial research with low-and moderate-risk agents.
Class IIA Biohazard Safety Cabinets provide personnel, product, and environment protection. Class II Cabinets differ in the proportion as 70% air is re-circulated within the cabinet through high efficiency particulate air (HEPA) filtration.
The biological safety cabinet class III is designed for work with bio safety level 4 microbiological agents, and provides maximum protection to the environment and the worker. It is a gas-tight enclosure with a non-opening, completely sealed, viewing window. Access to the interior of the cabinet is through a double-door pass-through interchange box that can be decontaminated between uses.
Nowhere is comfort and safety more essential than when working with hazardous materials in a biological safety cabinet. Operating in cramped conditions can make even the simplest procedure not just difficult and time-consuming â€“ but often hazardous. Ergonomically advanced design and sophisticated controls provided in NIKHTISH bio safety cabinets give maximum operator comfort and safety.
