ABSTRACT:
A device for removing a cap from a test tube under sanitary conditions has an enclosure receiving at least part of the test tube and cap and isolating them from the atmosphere. A plunger reciprocable in a cylinder sealed to the enclosure can be hand operated to close normally spread gripper members against the cap flange and to pull the so-gripped cap from the tube. Any discharge from the just-opened tube is confined within the enclosure. The uncapped tube can be removed from the enclosure, and the cap also can be removed for reuse.
