ABSTRACT:
Non contaminating stopper remover means for removing test tube stoppers of the type having a center portion extending into the test tube and an upper portion having a continuous edge over the edge of the test tube stopper remover. A hollow cylindrical member has an open end adapted to fit over the stopper inserted in the test tube. The stopper remover may have an inwardly extending rim or binding surface adapted to fit the extending upper portion of the stopper so that the stopper may be removed by slipping the stopper remover over the stopper and squeezing, pulling or bending to one side of the test tube. The stopper remover is longer than the stopper so that when the stopper is removed any contamination by the stopper is prevented.
