A Pass Box is a controlled transfer device used in pharmaceutical industries, cleanrooms, laboratories, and hospitals to move materials between two areas with different cleanliness levels while preventing contamination.
It acts as a barrier system that reduces human movement inside critical areas and helps maintain sterile and hygienic conditions as per GMP standards.
A pass box is typically made from stainless steel (SS 304/316) and is equipped with an electronic or mechanical interlocking system, ensuring that only one door opens at a time. This prevents direct airflow and contamination transfer between rooms.
