Two positions Auto polymer system PSL-Rheotek
Integrated glass capillary viscometer system suitable for measuring the dilute solution viscosity of a wide range of polymers dissolved in acids, organic solvents or water, including PA, PET, PVC, PLA, PBT, PC, PE, PP, Cellulose Acetate, Inks, bio-polymers and other.
The PSL Rheotek RPV-1 Auto provides a reliable and precise system for measuring dilute solutions of polymers.
Auto systems not only combine the control of the sample preparation process but also the sample dissolution.
The RPV Auto system controls the heating and stirring times of polymer solutions, as well as cooling prior to
measurement.
Sample dissolution control is critical in order to ensure that polymer solutions, such as PET, do not degrade prior
to measuring their intrinsic viscosity.
The RPV-1 Auto automates the manual steps set out in standard methods, minimizing the variability of results.
Flow times are measured automatically using ASTM Ubbelohde viscometer tubes supplied with ISO 17025
certificates of calibration.
Cleaning is carried out in-situ utilizing solvents and a safe vacuum system.
The comprehensive RPV-1 Auto software program records all measurement data as well as calculating a wide
range of results.
