What is static pass box?

A static pass box is a sealed enclosure used in controlled environments, such as laboratories or cleanrooms, to transfer materials between areas with different cleanliness or contamination levels without direct human contact. It typically features doors on both sides that can only be opened one at a time to maintain sterility. Static pass boxes are equipped with HEPA filters to minimize airborne contaminants and are often used for transferring sensitive items like pharmaceuticals, electronics, and biological samples.
