Our pass-through box strictly follows the US Federal FS209E standard, ISO14644-1, and GMP/US FDA technical requirements.

Our pass box is mainly used in Bio-safety labs, Pharmaceutical factories, food processing, Microelectronics factory buildings, Solar cell factory buildings, Photoelectric engineering, Operating rooms, LCD factory buildings, and Scientific Research Institute State.

Static Pass Box

The cleanroom pass box is the most effective device to prevent contamination. It is characterized by a double-door interlock, which effectively reduces the number of staff members entering the purification room due to the transport of goods, and prevents external air pollution. The complete set of equipment is economical and is the best transfer device for the purification room. This equipment is widely used in microtechnology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCDs, electronics factories, and other places that need air purification.

Dynamic Pass Box

The dynamic pass-box is the auxiliary device to the clean room. It is used to transfer small objects between clean rooms and non-clean rooms, to reduce the frequency of opening the doors and the pollution of the clean room can be reduced to a minimum. Ultraviolet light is installed in the pass box, and the articles are sterilized by ultraviolet light before entering the clean area. 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.

VHP Pass Box

VHP pass box technology refers to the technology of vaporizing liquid hydrogen peroxide into hydrogen peroxide steam and using vaporized hydrogen peroxide to sterilize objects at low temperatures.

VHP has a broad spectrum of bactericidal properties and can effectively kill all types of microorganisms such as bacteria, fungi, molds, viruses, and bacterial spores. Currently, it is found that the most difficult microorganism VHP to kill is thermophilic fat spores, so the biological indicator used for VHP sterilization verification is thermophilic fat spores.

Biosafety Pass Box

Biosafety pass box airtight transfer Windows are mainly used in rooms with airtight requirements in high-level biosafety laboratories (BSL-3, BSL-4, ABSL-3, ABSL-4), which can solve the airtight problem of logistics channels. The double doors of the airtight transfer window adopt mechanical and inflatable double sealing methods to ensure the air tightness of the logistics channel, that is, the high elastic sealing ring and inflatable sealing ring are installed on the door panel of the transfer window, and a double sealing belt is formed between the door and the door frame through the pressing mechanism. As an item transfer equipment, the transfer window is mainly used for the transfer of small items between the low pollution probability area and the high pollution probability area. The double door adopts an interlock device to avoid direct communication between different areas; At the same time, the VHP disinfection interface is set up, which can be used to connect the VHP disinfection equipment to disinfect the items in the pass box, which can effectively reduce the contamination in the transfer process.
