Esco's Labculture® Class II Type A2 Biosafety cabinet (LA2-4A2 model) has been certified as fully compliant to the requirements of the US Standard NSF49 for Class II (laminar flow) biosafety cabinetry. 22 types of stringent performance tests were conducted by NSF International in the USA, which included a full set of microbiological performance tests with bacterial spore samples, airflow tests, rigorous construction and design evaluation tests and others described in NSF/ANSI 49-2004 standard.

In addition, the LA2 models have also been certified to the UL 61010A-1 (Underwriters Laboratories, Inc) safety requirements for "Electrical Equipment for Laboratory Use", for USA (UL) and for Canada (UL-C). UL certification is a pre-requisite for NSF49 certification.

Launched in January 2004, Esco's Labculture® biosafety cabinet features many unique, state-of-the-art developments which include superior ULPA filters with 99.999% efficiency, a microprocessor-based control system, BioCote® anti-microbial powder-coated body and laminated shatter-proof safety glass.

Esco Labculture® Class II Type A2 Biosafety cabinet series have also been certified to the European standard for microbiological safety cabinets, EN12469:2000 in 2004.

Esco is now 1 of 11 biosafety cabinet manufacturers in the world to be certified to the stringent NSF49 standard, and one of few to have products certified to both NSF49 and EN12469 standards.
