A pass box (also called a pass-through box or transfer hatch) is a compact, airtight chamber built into the wall between two controlled environments to allow safe transfer of materials without exposing the receiving area to contaminants. Pass boxes form a physical barrier that limits particle and microbial ingress during transfers and are widely used where clean-room integrity is critical. Their core functions are to provide contamination-controlled material transfer, reduce personnel movement between zones, and enable decontamination or sterilisation cycles (UV, VHP, HEPA airflow) within a confined space before entry into the clean zone.
