Brookfield Viscometers, Rheometers & Texture Analysis

Spiral Adapter
A Pump-type Sensor That Directly Measures Viscosity Of Pastes

Designed for measuring the viscosity of heavy paste-like materials and non-flowing products. Provides variable shear rates for detecting pseudo-plastic and thixotropic behaviour when used with standard Brookfield Viscometers and the DV-III Ultra Rheometer.

The Spiral Adapter has an inner, threaded spindle surrounded by a concentric outer cylinder. This combination causes the sample to be continually pumped up through the Spiral Adapter. The material reaches a steady state of flow during which viscosity is measured. The steady-state measurement is less sensitive to sample handling and minor material variations than other viscosity measuring methods.

At its various rotating speeds, the Brookfield Viscometer/Rheometer provides viscosity data at different shear rates. The resulting rheogram from an up/down speed ramp supplies important information on the psuedo-plastic and thixotropic behaviour of the test material.
