Abstract
Improved compound gripper device particularly useful with laboratory glassware and suitable for use with low or high gripping forces. When gripping forces are high, external gripper member is displaced into a resilient gripping pad which pad is of the type which provides the high-friction gripping force. On release of the gripping force, the external member is released and serves as a means to provide positive displacement of the object being held from the resilient, high-friction, gripping element.
