Like most of the other glassware in our catalog, this part is made from Schott Duran® glass or its equivalent. This part is made with the same size tubing as the corresponding CG-100 inner joint. In the selection menu, OD refers to the outer diameter of the tubing and W to the wall thickness.
The matching inner joint is also available as are the corresponding joints in the more common medium length. For a discussion of standard taper joint sizing, see the Joints entry in the Glassware Gallery.
For plastic Keck™-style joint clips see item # 24000.
