Features & Benefits

miniPV®-HX is a fully automated, single-bath, benchtop viscometer with a 10-position sample handler for unattended processing and testing of dilute solution viscosity of polymers in aggressive solvents and corrosive acids. The Ubbelohde-style tube covers a dilute solution polymer viscosity range between 0.02 mm²/s (cSt) and 700 mm²/s (cSt) from 15 °C to 100 °C. Available tubes cover a kinematic viscosity range of 0.3 mm²/s (cSt) to 1200 mm²/s (cSt) with extended KV range tubes available upon request. For methods ASTM D789, ASTM D1243, ASTM D1795, ASTM D2857, ASTM D3591, ASTM D4243, ASTM D4603, ASTM D5336, ISO 307, ISO 1628-1, ISO 1628-5 and ISO 5351.
