This month will see the launch of the second generation of Esco's Airstream Class II (AC2) biosafety cabinet, used for potentially hazardous applications such as cell culture, virus propagation and animal tissue handling.
Like its predecessor, the new system makes use of ULPA rather than HEPA filters to provide what Esco claims is best in class performance. This results in a typical efficiency of 99.9998 per cent at 0.3 and 0.12 microns (compared with typical HEPA filters which are 99.99 per cent efficient at 0.3 microns), providing a higher level of operator, product and cross contamination protection.
The new version features many improvements such as an ergonomically-designed sloped front and a new work tray design that improves cleanability as well as airflow uniformity. Airstream® biosafety cabinets are now also available in two different versions: with transparent UV-resistant glass sides (E-series) or with full stainless steel interior (S-series).
A backward curve motorised impeller technology is used in the cabinet, replacing conventional blowers, and ensures better air uniformity and improved energy efficiency for lower operating costs, according to Singapore-based Esco .
A microprocessor control system (Sentinel) alerts the user of any unsafe operation conditions, and an integral raised armrest in the cabinet is comfortable for operators and has the added bonus of preventing accidental blocking of the front air grilles during operations.
Esco noted that the Airstream Class II (AC2) has been tested to conform to the 5726 (British), DIN 12950 (German), NF X44-201 (French) standards for microbiological EN12469 standards issued by the European Commission, which replaced the BS safety cabinets in 2001.
