miniPV Single-Bath Dilute Solution Polymer Viscometer

CANNON product

For Dilute Solution Viscosity of Polymers in Organic Solvents and Aqueous Solutions. ASTM D 446 and ISO 3105. miniPV® is a fully-automated, single sample, benchtop viscometer for testing dilute solution viscosity of polymers in organic solvents and aqueous solutions. The Ubbelohde-style tube covers a 100-fold viscosity range between 0.3 cSt and 5,000 cSt from 20 °C to 100 °C.

The miniPV 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 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.

Support for a sequence of samples is available with the optional autosampler. VISCPRO II is unique in its ability to perform the Huggins-Kraemer determination of intrinsic viscosity in addition to single-point methods based on Billmeyer and on Solomon Ciuta. Multiple viscosity calculations are also available, leading to relative, inherent, and reduced viscosity determinations. In addition, the software provides flexible and sophisticated control of data export options and database management.

The MiniPV is a fully automated, laboratory bench-top unit, ideal for testing polymer solutions dissolved in mild organic solvents and aqueous solutions from 15°C to 100°C, for single sample viscosity testing.
