Two positions Auto PET polymer system PSL-Rheotek

RPV-1 (2) AutoPET with heating/stirring in Auto Sampler

RPV-1 (2) AutoPET Request Quotation

For minimal operator contact with solvents, the PSL Rheotek RPV-1 (2) AutoPET two position AutoPET is your first choice. The viscometer system is configured specifically for fully automating the Intrinsic Viscosity of polyethylene terephtalate (PET) in accordance with ASTM D4603 and/or ISO 1628 Part 5. The AutoPet is the most advanced fully automated viscometer available for polyester.

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

Product Description

Details

The PSL Rheotek RPV-1 (2) AutoPET 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.
