The primary purpose of a MSC (Microbiological Safety Cabinet) or BSC (Biological Safety Cabinet) is to serve as a means to protect the laboratory worker and the surrounding environment from pathogens. All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful microorganisms.
MSC:s are used on a daily basis for hours. Besides protection of user and sample material, the human design factors (ergonomics) of the work become more and more important. This includes reduction of the noise level (for a more convenient working atmosphere), a height adjustable stand or stool (for optimized sitting position), panorama side windows (more light within cabinet), angled front sash (enables better sitting position) as well as strong light sources (better view within cabinet) to improve the working conditions.
