No. 583 Capilograph™ (Capillary Rheometer)

Description

The Capilograph measures melt viscosity of polymers by detecting the shear rate and shear stress of melt polymer when it flows out of the capillary die.

Die swell and melt strength can also be measured by equipping it with optional attachments.

The twin bore barrel model (F-2) allows easy Bagley & Weissenberg-Rabinowitsch correction (for determination of true viscosity) or elongational viscosity calculation.
