The dynamic pass through box is the auxiliary device to the clean room. It is used to transfer small objects between clean rooms and non-clean rooms, so as to reduce the frequency of opening the doors and the pollution of the clean room can be reduced to a minimum.
Cleanroom Dynamic Pass through Box for Microbiology Lab
Ultraviolet light is installed in the dynamic pass through box, and the articles are sterilized by ultraviolet light before entering the clean area for microbiology lab. On the one hand, it plays the role of an airlock to prevent the high pressure in the high-level clean room from being leaked, and on the other hand, it realizes the self-purification effect during the re-transmission process to ensure the self-cleanliness of the items entering the clean area and reduce the cross-contamination brought by the objects.
