GROUND GLASS JOINT TOOLS

Ground glass joint holders, also known as GonG holders, are used to hold or form the ground glass joints.

The male holders hold the female glass joints, and the female holders hold the male glass joints.

All of our holders are made from high grade, fine grain moulding graphite, and machined on CNC machines for accuracy.

Ground glass joint formers can also be found here.

The handles are custom turned metal and covered by our patented heat, chemical and flame resistant covers.
