Instron SR20 Capillary Rheometer

Capillary Rheometer (Instron SR20).

The following specifications and included options are:

• Piston-die type in accordance with ISO 11443 and ASTM D3835 with a twin/dual bore configuration

• Pressure transducer capable of reading up to 200 MPa

• Temperature ranage of operation: room temperature to 450 °C with a resolution of 0.1 °C and accuracy and

stability of 0.2 °C

• Interchangeable die set of sizes of 5 mm (Length to diameter ratio (L/D) ratio 5), 20 mm (L/D ratio: 20), 30 mm

(L/D ratio: 30)

• Screw speed up to 1200 mm/min

• A PVT system to obtain pressure-volume-temperature analysis of polymers tested that can manage multiple steps

of pressure and temperature.

• Supplied software with the instrument allowing for conducting experiments and tests such as flow curves, constant

piston speed and shear rates, Bagley corrections, Non-Newtonian Index calculations, power law and cross equation

fitting, elongation viscosity estimations, viscosity dependence on temperature analysis, and stress relaxation mode.

• Installation and in-person training are required in the purchase.
