RPV-1 Two positions Polymer Viscometer
Inquire productThe PSL Rheotek RPV-1 (2) provides a reliable and precise system for measuring dilute solutions of polymers.
The RPV-1 automates the manual steps set out in standard methods, minimizing the variability of results.
Systems can be configured with 1 to 4 measuring positions. Other options include sample preparation,
sample dissolution and auto sampler.
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 software program records all measurement data as well as calculating a wide
range of results.
