Using these integrated options ensures full integrity r4603 data from end to end in the measurement process.

Dissolution is carried out using a reaction block with stirring and heating at deg.

ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. The time for the solution to flow from the dd4603 to lower graduation marks is recorded. The solution and viscometer are placed in a constant asm water bath.
