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.
