Two positions AutoPVC polymer system PSL-Rheotek

RPV-1 (2) AutoPVC


RPV-1 (2) AutoPVC Request Quotation


The PSL Rheotek RPV-1 (2) AutoPVC two position AutoPVC viscometer system is configured specifically for fully automating the Inherent Viscosity or K-value of polyvinyl chloride (PVC) in accordance with ASTM D1243 and/or ISO 1628 Part 2.


Auto systems fully integrate sample preparation, sample dissolution & sample loading, as well as flow time measurement, cleaning and reporting of results. One or two heating and stirring zones can be configured to control the dissolution of batches of samples. Both heating temperatures and stirring times are computer controlled and samples are cooled prior to being automatically loaded into the viscometer. Typical sample throughput is 6 to 8 samples per hour with two measuring positions.

Product Description

Details

The PSL Rheotek RPV-1 (2) AutoPVC 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 PVC, 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.
