The Cold Water Rheology Kit provides controlled sample cooling for a Model 35 Viscometer. The circulating chiller is capable of regulated sample cooling; from ambient temperature to -10°C. The amount of time required to cool a 200 Centipoise silicone calibration fluid from room temperature to -7°C in approximately 30 minutes (with sample stirred at 100 RPM). The Digital Controller allows temperature regulation of +/- 0.1°C. Sample temperature is indicated on the display screen of the circulator bath.
