RPV-2 RSS Polymer Viscometer The RPV-2 RSS is suitable for determining the viscosity of polymers in dilute solution using capillary viscometers, in accordance with standard international methods of test. Typical applications include:
K-value, Reduced Viscosity - Poly (vinyl chloride) resins – ISO 1628 Part 2, ASTM1243 Inherent Viscosity, Intrinsic Viscosity - Polyester (PET) – ISO 1628 Part 5, ASTM D4603 Viscosity Number - Polyamides – ISO 307 Limiting Viscosity Number - Cellulose, aged electrical papers and cellulose – ISO 5351, ASTM D1795 Polymers and bio-polymers dissolved in acids, organic solvents and water – ISO 1628 Part 1, ASTM D2857
Polymer Concentrations are precisely prepared using the integrated sample preparation module, iSP-1. Solvent and solution flow times are measured precisely in calibrated glass capillary viscometers at a closely controlled temperature. Final results are calculated from the relative viscosity and the known concentration. The RPV-2 RSS Analyzer is configured with a Smart Sampler together with the optional integrated sample preparation module as well as a sample dissolution system, such as a shaker or magnetic stirring heating and cooling block.
The RPV-2 RSS is a self-contained Automated Polymer Analyzer. Features include: - XYZ sampler with in-line filters - Temperature controlled bath – with heating, stirring and cooling - One or two measuring positions - On-board control system, including power supply and PC - In-situ “safe-vac” cleaning and drying system - External parts include: PC monitor, keyboard, mouse, solvent and waste bottles.
The iSP-1 is a fully integrated sample preparation system. Samples are prepared on a weight to weight basis, designed to eliminate errors arising from volume and temperature. - Precision balance with drip tray - Precision syringe pump (or multiple pumps) - Comprehensive software - Multiple preparation methods © Poulten Selfe & Lee Limited 2017 PSL Terms and Conditions Apply Subject to technical change
