Capillary Breakup Extensional Rheometer (HAAKE CaBER 1)

The Capillary Breakup Extensional Rheometer (CaBER) is the only commercially available rheometer for measuring extensional properties.

The Thermo Scientific HAAKE CaBER 1 was designed by the Cambridge Polymer Group and is manufactured by Thermo Scientific.

Many different experimental techniques for measuring the elongational properties of non-Newtonian fluids have been developed over the last 30 years. All these techniques were difficult to operate, generated complex flows and therefore confusing results. As a consequence successful commercially available instruments did not exist – until the HAAKE CaBER 1.

Knowledge of the elongational behaviour of fluids is important for both industrial and basic research purposes. Complex flows that contain strong extensional components occur in many industrial processes and applications. Some examples are extrusion flows, coating flows, contraction flows and fibre spinning flows. Most materials exhibit very different responses in an extensional flow compared to a shearing flow. The thinning and breakup of a fluid filament that is analysed with the HAAKE CaBER instrument provides valuable information about the materials physical properties that rotational rheometers simply can not provide.

The HAAKE CaBER 1 is suitable for examining:

Adhesives – Measurement of tackiness – Solvent loss or gain
Associating polymers
Consumer goods – Filling of bottles – Time to breakup – Solvent loss – Processability
Food products – Stringiness/strand formation – Time to breakup – Relaxation of doughs – Elastic instabilities
Industrial resins – Relaxation time spectrum – Constitutive modelling – Spinnability
