The Tech Inc. Capillary Rheometer for Dope and Polymer Melts measures the shear viscosity of polymer melts and concentrated spinning dopes at the shear rates found in spinnerets and dies. A piston drives the sample through a heated capillary while pressure and speed are recorded.

Main components

Heated barrel with piston drive
Interchangeable capillary dies
Pressure transducer
Software for viscosity curves and corrections
Cleaning tools

Applications: Hollow-fibre and fibre spinning dopes, polymer melts, extrusion and moulding research.
