The PSL Rheotek RPV-2 determines the viscosity of polymers in dilute solution using glass capillary viscometers in accordance with ISO 1628 Part 1. Two modes are available allowing the user to select the calculation of Relative Viscosity either from flow times measurements (i.e. in seconds) or calculated viscosities. The RPV-2 will automatically determine Relative Viscosity, Reduced Viscosity, Inherent Viscosity, Intrinsic Viscosity and K-Value. The RPV-2 accommodates Ubbelohde/Suspended-Level type viscometers as specified in ISO 3105. The RPV-2 is compatible with a wide range of diluting acids and solvents. The iSP-1 Sample Preparation system can be used in conjunction with the RPV-2 to prepare samples on a precise weight to weight basis. Dissolution is carried out either using a wrist action shaker (WAS) or reaction block with programmable stirring and heating temperatures (SD-BM)
