Pass boxes are used to transfer material for blending, granulation or sterilization in manufacturing area and sterilization and

incubation in microbiology laboratory.

In some cases equipment parts are also transferred through the pass boxed in sterile manufacturing areas.

Pass boxes help to prevent the air flow from one area to another while transferring the material.

One door of the pass box opens at time and both the doors cannot be opened simultaneously.

Dynamic pass box works like an air lock or laminar air flow unit. Clean air enters in the pass box and prevents the entrance of the contamination. Dynamic pass boxes may be

B. Static pass box

Static pass boxes are simple boxes mounted between two areas and also known as passive pass boxes.

Area having higher cleanliness level shall have higher pressure that helps to prevent the entrance of contamination in the sterile area.

Ultra-violet light is also installed in the pass boxes to remove the contamination that may enter during the transfer of material. It should be replaced after 1000 burning hours.

Pass boxes should be cleaned with disinfectants at regular intervals.


Efficiency of the pass boxes should be verified by validation. Validation may be done by exposing the known population of the bacterial culture.
