A rigid body member is provided with one or more holes shaped to support a tube in an upright position, so that a person can manually grip and push a stopper downward over the tube, without the normal difficulty of having to grip both the tube and the stopper at the same time. In a preferred embodiment the body member is also provided with a base to support the body in a stable position on a work bench or the like, and is further provided with a rigid protrusion having a suitable diameter for use in removing the tube from the stopper.Other References
