The final frontier?

摘要

The weakest points of a cleanroom, where contamination is most likely to originate, are the points at which people and equipment enter and exit the controlled area. There are various technologies available to limit the potential risk, including airlocks, pass-throughs, autoclaves that operate through the wall and air pressure differentials. This is fine when the cleanroom is handling relatively small items that can be transferred in and out on trays, trolleys or pallets.
