YORCO Biological Safety Cabinets or Bio-Safety Cabinets (BSC) are of International Quality and are considered top-of-the-line by it’s very large number of regular users. YORCO Biological Safety Cabinets (BSC) offer a combination of cabinet design and filtration systems to protect Personnel, Work Area, Product and the Environment from biological particulates. The BSC is engineered for work with low, moderate and high risk organisms that pose a biohazard concern. Bio-Safety cabinet with a constant face velocity airflow creates a performance envelope within and throughout the work surface to minimize or eliminate contamination.
High Performance Airflow
The BSC cabinet design regulates air velocity through latest Minipleat HEPA Filters and apportions the down flow air across the work surface to create a containment zone. Negative pressure plenums and aerodynamically shaped cabinet surfaces capture airborne contaminants before they can enter the work area.
Ease of Use
An ergonomic 10o sloped front improves comfort. Uniform interior lighting and a glare resistant toughened glass front Sash optimizes human interface.
High Capacity Filtration
The front-access Supply & Exhaust Minipleat HEPA Filters in extruded anodized aluminum frame are designed to capture particulates with 99.97% efficiency for 0.3 microns. A closed cell peripheral gasket surrounds the filter housing to prevent particulate bypass and escape to the work area or laboratory.
Specialized airflow system disperses air evenly over the supply and exhaust HEPA filters, and eliminates potential leaks by surrounding the positive pressure chamber with negative pressure.
The Microprocessor Controller is available in ‘Ex’ Models only for continuous supervision of all cabinet functions, with universal icon touchpad buttons, simplified, one-handed access to On/Off and alarm monitoring system.
