Polymers - ASTM D2857

The PSL Rheotek RPV-2 determins the dilute solution viscosity of polymers in accordance with the Standard Practice ASTM D2857. Two modes are available allowing the user to select the calculation of Relative Viscosity either from flow flow times measurements (i.e. in seconds) or calculated viscosities. The RPV-2 will automatically graph Reduced Viscosity and Inherent Viscosity from a range of concentrations generating the best fit lines to extrapolate Intrinsic Viscosity at the point of zero concentration. (Also refereed to as the Limiting Viscosity Number). 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). Typical applications include Polyamide, Polycarbonate, Poly (Methyl Methacrylate, Poly (Vinyl Chloride).
