RPV-1 Polymer Viscometer​

RPV-1 Two positions Polymer Viscometer PSL-Rheotek

RPV-1 Polymer Viscometer

The PSL Rheotek RPV-1  (2) Two position polymer viscometer system is suitable for measuring the dilute solution viscosity of a wide range of polymers dissolved in acids, organic solvents or water, including PA, PET, PVC, PLA, PBT, PC, PE, PP, Cellulose Acetate, Inks, bio-polymers and other.

• RPV-1 systems are designed to be integrated with the SP-1 Sample Preparation system for polymers.
• Other options include RPV275 Sample dissolution and RSS Rheotek Smart Sampler.
• The 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.

POLYAMIDE RV & VN

Polyamide is also known as nylon. Today this is used in airbags, automotive components and much more. Most people will be familiar with the product from consumer textiles. Depending on the grade of nylon, it may be dissolved in Formic Acid, M-Cresol or sulphuric acid.

PET Intrinsic Viscosity

PET a polymer, which is familiar to most of us. It is used world wide for drinks bottles. Under the name of polyester, it is also widely used in the textile industry. Most of the PET resin manufacturing plants in the world test the IV of their output product in compliance with ASTM D4603. The procedure of this test involves dissolving the polymer in highly hazardous chemicals. The automated viscometer from PSL Rheotek, the RPV-1, helps to minimise the operator exposure to the hazardous chemicals.

PVC K-Value

PVC is a strong, lightweight polymer commonly used in construction. Most of us will be familiar with it from PVC pipes used for domestic plumbing. In order to test the K-Value of the PVC, it is necessary to dissolve it first. ISO 1628 part 2 is the most common method. The PVC is dissolved in cyclohexanone prior to measurement.
