Inner Joints, Ground Glass, Standard Taper, Medium Length, w/ Hooks

Item #: CG-107

Normal Availability: 1-3 business days

Product Description

Like most of the other glassware in our catalog, these parts are made from Schott Duran® glass or its equivalent. These inner ground glass joints have two glass hooks 180° apart just above the grind that can be used to connect the joint to other apparatus with CG-110 stainless steel springs (sold separately).

The matching outer joint is also available (item # CG-108) as are corresponding joints without hooks. For a discussion of standard taper joint sizing, see the Joints entry in the Glassware Gallery.

In the product selection menu, OD refers the outer diameter of the glass tube, and W refers to the thickness of the glass tube wall.

Note: The term "medium length" does not refer to the overall length of this component. It refers to the length of the ground glass portion only. For example, size 14 standard taper joints come in 10, 20, and 35 mm lengths, so a 14/20 joint is "medium" in this context.
