Esco announces the publication of a series of white papers focused on the microbiological testing of biological safety cabinets.
Microbiological testing is carried out to validate the cabinet's ability to provide personnel, product and cross-contamination protection, and is specified in the NSF49 and EN12469 standards.
The white papers document the outcome of Esco's research into the following topics: personnel protection tests on biosafety cabinets with widths less than 0.9m (3ft); and nebulizer placement for cross-contamination tests.
In the first study, alternative distances of slit air samplers from the cabinet interior side walls were evaluated on cabinets with widths less than 0.9m (3ft) and a 1.2m (4ft) typical width model.
In the second study, differing nebulizer placements as specified in the NSF49 and EN12469 standards were compared on a single cabinet.
