The Difference Between an Ultra-Clean Workbench and a Biological Safety Cabinet : Many people are confused about the difference between an ultra-clean workbench and a biological safety cabinet. Today, we’ll take a closer look at what sets them apart. An ultra-clean workbench (also known as a clean bench) is designed to protect the materials or samples being handled inside it. It uses HEPA filters to maintain a dust-free environment, but it does not provide any protection for the operator. In contrast, a biological safety cabinet (BSC) is a more advanced system that protects both the samples and the user. It creates a negative pressure environment that prevents harmful particles from escaping, making it ideal for handling infectious agents or hazardous substances.
