RPV-1 (2) RSS Request Quotation

The PSL Rheotek RPV-1  (2) RSS Two position polymer viscometer system with smart sampler is 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 RPV-1 is designed to be integrated with the SP-1 Sample Preparation system for polymers.

Part No. RPV-1 (2) RSS

Product Description


The PSL Rheotek RPV-1 RSS provides a reliable and precise system for measuring dilute solutions of polymers.
The RPV-1 RSS automates the manual steps set out in standard methods, minimizing the variability of results.
Systems can be configured with 1 or 2 measuring positions with the Smart Sampler. Other options include sample
preparation and sample dissolution.
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 RSS software program records all measurement data as well as calculating a wide range of results.
