Two positions PP/PE viscometer with sampler
The PSL Rheotek RPV-1 (2) RSS HT – two position PP/PE viscometer with sampler is specially adapted for measuring low and medium density polyethylenes (PE) and polypropylenes (PP) at 135 °C.
The RPV-1 HT is designed to be integrated with the (hyperlink) SP-1 Sample Preparation system for polymers.
Other options include SD-1 Polymer reaction block.
Test Methods PP/PE:
ISO 1628 Part 3
The PSL Rheotek RPV-1 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.
High temperature Systems can be configured with 1 or 2 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.
