RPV-2 Pulp Rheotek Pulp Viscometer - Dilute Solution Viscosity of pulp & cellulose The RPV-2 is suitable for determining the intrinsic viscosity of pulps and purified celluloses, as well as electrical papers in dilute solution using glass capillary viscometers, in accordance with standard international methods of test. Typical applications include: •
Intrinsic Viscosity – Cellulose – ASTM D1795
Limiting Viscosity Number – pulp – ISO 5351
Average viscometric degree of polymerization – new and aged electrical papers - ASTM D4243, IEC 60450
Viscosity of Pulps – Cellulose solution – Tappi T230
