Solvent and solution flow times are measured at 30 deg. C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements.

The method requires that three successive flow times are obtained within 0. The RPV-2 software automatically calculates the Intrinsic X4603 from each single determination using the Billmeyer equation. Dissolution is carried out using a reaction block with stirring and heating at deg. C with a programmable timer. Using these integrated options ensures full integrity of data from end to end in the measurement process.
