Adapter, 75° bent, 14/23 Joint, Compatible with 14/20

Adapter, 75° bent, 14/23 Joint, Compatible with 14/20

Borosilicate Glass. Both Joints are 14/23, Compatible with 14/20.

With an standard taper inner joint at each end. Both joints are the same size. Angle is 75°.

Standard Ground Joint or Conically Tapered Joints( for both European ISO and US standard)

The conically tapered ground glass joints typically have a 1:10 taper and are often labeled with a symbol consisting of a capital T overlaid on a capital S which stands for "Standard Taper". This symbol is followed by a number, a slash, and another number. The first number represents the outer diameter in millimeters (mm) at the base of an inner joint or the inner diameter in millimeters at the tip of an outer joint, in both cases where the applicable diameter is at a maximum in the joint. The second number represents the ground glass length of the joint in millimeters. The most commonly encountered joints are 14/20 and 24/40. These joint sizes apply only to glassware in the US. There are also European ISO standard joints with common joint sizes of 10/19, 14/23 and 29/42. The US and ISO joints differ only in the length not in the slope, and can be used in combination. The stopper joints of chemical bottles, volumetric flasks, and separatory funnels often do not use the precision standard taper ground glass joints. Stopper joints are designated (if at all) only by the maximum diameter number.
