Our glassblowers work to the highest standards of their craft. Every day, low thermal expansion borosilicate glass tubing is turned into PSL Rheotek glass capillary viscometers. All viscometers are calibrated in our UKAS accredited laboratory. Calibration is performed one step away from the Master Viscometer Scale giving you the highest level of traceability available.
Master Viscometers are much longer than normal viscometers and require extra care and a patient mindset to calibrate them. Laboratory Technician from our calibration laboratory can testify to that.
