ABSTRACT:
A clean room gripper having sliding jaws and including a pressurized piston cylinder and actuator section for moving the jaws towards and away from one another. The jaws are in the form of upper and lower finger sections, with the lower section being provided with a sliding seal located between it and a mating outer surface of an evacuated chamber, whereby no particles or dust created within the unit because of mechanical action will be allowed to escape from the gripper during operation to add to contamination of the environment in a clean room.
