Standard Taper Ground Joints
Replacement Parts
The Standard Taper designation for a joint indicates that it complies with the requirements of ASTM E675 for stopcocks, stoppers, and reagent bottle necks and E676 for interchangeable joints. All mating parts are finished to a 1:10 taper. For volumetric and Erlenmeyer flasks, graduated cylinders, etc., a single number indicates the size of a joint at the top of the neck; however, there are differences in dimensions between the bottle and flask stoppers (see the groundware technical section in this catalog).
