RPV-1 Systems

The PSL Rheotek RPV-1 provides a reliable and precise system for measuring dilute solutions of polymers, pulp & cellulose.

The RPV-1 automates the manual steps set out in standard methods, minimizing the variability of results.

Standard RPV-1 systems include:

● RPV-1 Polymer ● RPV-1 Pulp ● RPV-1 PP & PE (two positions)

Systems can be configured with 1 to 4 measuring positions.

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.
