Borosilicate Tubing and Rod: Sizes and Tolerances
|
These are the nominal sizes and tolerances for American-made tubing and rod, both Pyrex 7740 and Kimble KG-33, and European-made Schott Duran. They are functionally equivalent for our purposes. They are "33-expansion" glasses. You will note that American standard and special wall tubing is all referenced in metric sizes, and medium and heavy wall is referenced in English measure, for some obscure historical reason. In this listing we have left off the fractional English equivalents for reasons of space. If the OD is listed as a non-integral metric measure, it is generally a fraction in inches; 15.9 mm is 5/8", 63.5 mm is 2-1/2", etc. After many years of working glass and dealing with customers who like a variety of measuring systems, we have become pretty much ambimetric. We do use some Schott Duran tubing made in Germany, which is all metric; the sizes and tolerances are shown here. |
 |
A word about tolerances: Corning and Kimble specify the diameters of their tubing as being in tolerance at each end of a four foot length of tubing; what might happen in between is irrelevant to them. Generally it's a pretty good bet that it's all in spec. Usually tubing is reasonably, but not perfectly round. If you need perfection, precision bore tubing is available, but at relatively high expense.
See our page for the standard sizes of Schott tubing.
The tubing designations are:
- Standard wall - SW
- Medium wall - MW
- Heavy wall - HW
- Special wall - SpW
- Capillary - Cap
