Clean Room Transfer Window Multiple Layers Pass Through Box for Lab

The pass box is an airflow isolation device in the clean room to ensure that cross-contamination is avoided when items are transferred. Its interlocking function ensures that once one of the doors is opened, the other is locked for protection, thereby avoiding the cross-contamination of air flow between two different levels of rooms. Its interior is equipped with ultraviolet germicidal lamps, which can effectively kill microorganisms or bacteria entering the inner chamber of the transfer window and maintain a clean environment for the inner chamber. It is widely used in hospitals, pharmaceutical factories, biological laboratories, cosmetic factories, electronics industry, food processing industry and other places.
