Select Series NMR Sample Tubes For Ceramic Turbines

Ceramic spinner turbines, often relied upon for variable or high temperature applications, are manufactured to extremely precise dimensional specifications.

Unlike conventional room temperature turbines made from polymers such as POM (acetal, or polyoxymethylene) and Kel-F (PCTFE, or polychlorotrifluoroethylene) or even variable temperature turbines made from PEEK (polyetheretherketone) which can flex and accommodate larger diameter tubes to a certain degree, most ceramic turbines will not tolerate even a slightly larger diameter tube.

Ceramic turbines, composed of a very hard, rigid and brittle refractory substance, cannot flex in the slightest degree, and many of the ones currently available do not incorporate any design features permitting some degree of flexure.

To compensate for this inability, the inner diameter of ceramic turbines must be very precise and uniform from one to another, ensuring consistent performance across multiple turbines and tubes.

Accordingly, the NMR sample tubes used with ceramic turbines must meet stringent dimensional specifications as well.

When working under variable temperature conditions, the tube diameter specifications narrow and tighten even more to take account of any slight thermal expansions or contractions that can result.

To meet this stringent diameter requirement, Norell has developed a new line of NMR sample tubes, including both 5mm and 3mm O.D. sizes, that adhere to strict outside diameter specifications that are very tightly controlled.
