Polymer Viscometer (PSL RHEOTEK)

The PSL-Rheotek RPV-3 Polymer Viscometer is suitable for measuring the dilute solution viscosity of a wide range of polymers. Applications include PA, PET, PVC, PLA, PBT, PC, PE, PP, Cellulose Acetate, Inks, Biopolymers, Pulp and cellulose.

More details

Polymer Viscometer

The PSL Rheotek RPV-3 polymer viscometer offers an all-inclusive package of technology for solution viscosity test work. Accurate control of the very low concentrations employed in iv test work ensure high quality of test results. Automating the viscosity measurement work provides timely information for product specification and process control. K-value, viscosity number, relative viscosity results also available as per relevant test method.

With automation of flow time determination, results calculation, sample removal, sample path cleaning and sample path drying, the RPV-3 will save a lot of time in the polymer plant laboratory.

Full Method Compliance

Software configurations for all the most common test methods of solution viscosity are available as shelf products. So far, the following methods are covered: ASTM D4603, ISO 1628, part 1-5, ASTM D2857, ASTM D789, ISO 307. New methods are added on a continuous basis. An RPV-2 coded with correct method parameters and equations for calculations of results is a guarantee of full method compliance in the day to day testing work. The capillary tubes installed in the unit are standard ASTM Ubbelohde.

Automated functions include:

  • Sample push up
  • Flow time determination
  • Results calculation
  • Self-check of results quality
  • Sample removal
  • Sample path cleaning
  • Sample path drying
