Pass Boxes: Ultraviolet-Bathed Portals used for passing potentially contaminated items out of the laboratory.
Pass box is a kind of laboratory equipment which is used for transferring the materials from and into the Clean Room or the uncontrolled environment to the controlled environment. Controlling the ingress of particulate contamination into Clean Rooms and other controlled environments is paramount in order to maintain the integrity of products and processes.
Personnel traffic is the most important factor which should be controlled. Pass Box allows materials to be transferred into the controlled environment without actual personnel movement. Pass Box may also be used to protect the external environment from egress (the act of coming and going our) of contamination, for example, in biological safety laboratory applications.
Pass Box is equipped with the UV lamp which is used for sterilization/bacteria control. Pass box is provided with two interlocked doors, when one door is open the other door cannot be open, in this way it prevents the direct contact between the connected areas. A Reliable Interlock System prevents the two opposite doors of the Pass Box from being opened at the same time, to maintain thestability of the Clean Room atmosphere.
Salient Features of Pass Box

- Corrosion resistance
- Good quality raw material
Major application areas
- Factories
- Laboratories
- Drug & Pharma industries
- Research and development laboratory
Pass Box allows laboratory personnel to stay within the Clean Room instead of moving to different parts of the lab to fetch tools or materials, therefore eliminating a potential cause of contamination. When a door of a Pass Box is opened, a Laminar Air Flow begins inside to safeguard the cleanliness of the materials and of the Pass Box interior. Some types of Pass Box include built-in high velocity showers of HEPA-filtered air that spray materials entering or exiting the Clean Room. Optional Pass Box fixtures include Fluorescent Light Tubes.
