PSL Rheotek offers a comprehensive range of precision calibrated glass capillary viscometers. Viscometers are made by our experienced glass blowers from high grade borosilicate glass tubing. PSL Rheotek viscometers are used by refinery, testing and research laboratories throughout the world and enjoy a high reputation for quality workmanship and accuracy of calibration.

Viscometer calibration is performed on-site by our UKAS accredited ISO 17025 calibration laboratory. The PSL Calibration Laboratory maintains a master viscometer scale in accordance with ASTM D2162. All calibration data us directly traceable to international standards.

PSL Rheotek bitumen viscometers are suitable for measuring a wide range of liquid asphalts, bituminous binders and asphalt cements. For vacuum capillary viscometers, a bitumen vacuum system is available. Other accessories include viscometer bath, silicone bath oil and viscosity oil standards.

PSL Rheotek glass capillary viscometers are suitable for a wide range of applications. Applicable petroleum testing methods include ASTM D445, D446, D2162, D2170, D2171, ISO 3104 & ISO3105. Other applications include polymers, cellulose, blood and plasma.
