CANNON product

For Dilute Solution Viscosity of Polymers in Aggressive/Corrosive Solvents .ASTM D789, ASTM D1243, ASTM D1795, ASTM D2857, ASTM D3591, ASTM D4243, ASTM D4603. 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. 

Category: Tag:


The miniPV-HX from CANNON Instrument Company is an essential tool for the measurement of polymer solution viscosities. Its accuracy and convenience are based on the masterful design of temperature control, fluid handling, sensor technology, and automation.

Complete control of the instrument is provided through VISCPRO II software which also facilitates procedural tasks such as calibration, data entry, method specification, calculation selection, report formatting, and data exporting. The miniPV-HX occupies roughly the same footprint as an analytical balance, yet is able to provide a high level of automation which includes sample loading, temperature equilibration, flow time measurement, and cleaning of the entire system between measurements. And is Chemically Resistant to Solvent and Acid.
