Abstract

The invention is directed to a lock system for permitting objects to be ped from a contaminated chamber into a container which is disposed in a contamination-free chamber and docked to the lock system. The lock system of the invention includes a displaceable insert mounted on a partition wall separating the chambers. The insert is in the form of a round disc rotatable about its center point. The disc includes lock openings having different cross sections which are arranged on a circle concentric to the center of the disc. The lock system of the invention permits objects of different shape and size to be passed through the lock along only one removal path.
