Malvern Instruments has introduced a new range of low-temperature control options for the Malvern Rosand range of capillary rheometers. High-pressure capillary rheometry is a well-established method for simulating the processing conditions of molten polymers at high temperatures. These two new low-temperature control options, designed for the RH7-D/RH10-D and RH2000 rheometers, enable capillary rheometry to be applied to an extended range of materials. They comprise cooling coils with a fluid circulator for measurements from 5 degrees C to 50 degrees C, and an option for cryogenic cooling using liquid nitrogen for measurements to minus 40 degrees C.
