U.K.-based Malvern Instruments Ltd. has introduced a range of low-temperature control options for the Malvern Rosand brand of capillary rheometers.
High-pressure capillary rheo-metry is a well-known method for simulating the processing conditions of molten polymers at high temperatures. Malvern's new low-temperature control options enable rheometry to be applied to a larger range of materials.
The options use cooling coils with a fluids circulator for measurements from 11°-122°F. An option for cryogenic cooling uses liquid nitrogen for even lower temperatures.
The options are compatible with the full range of capillary dies for Malvern Rosand rheometers RH7-DRH10-D and RH2000.
The company is based in Malvern, England. The U.S. unit, Malvern Instruments Inc., is in Southborough, Mass.
