Omnitek U-Visc Automatic Viscometry System

Descriptions

The Omnitek U-Visc is the next generation of completely automatic viscometry systems. The system combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis. While offering full compliance with ASTM D445/D446, the specially designed viscometer tubes cover a 100-fold range, e.g. from 1 to 100 mm2/s. The tubes are based on the well-known and proven Ubbelohde design, but only require 8-16 mL of sample and approx. 12-15 mL of solvent for cleaning.
