This hexagonal head borosilicate hollow glass stopper has a 24/40 ground glass joint and is 2-1/2 inches in height.

The hexagonal shape of the head prevents it from rolling off the bench top. Its flat surface will also permit it to be inverted and placed on end, thereby preventing possible contamination of the ground glass surface.
