The Thermo Scientific Haake CaBER is the only commercially available
instrument for measuring the extensional rheology of fluids. CaBER
stands for Capillary Breakup Extensional Rheometer. This rheometer
is very easy to use for quality control and research of fluids.
Complex flows that contain strong extensional components occur in
many industrial processes and applications like extrusion flows,
coating flows, contraction flows and fiber spinning flows. Materials
that identically or similarly behave in a shearing flow can behave
completely different in an extensional flow. Therefore, the knowledge
of the elongational behavior of fluids is important. The thinning and
break-up of a fluid filament that is analyzed with the HAAKE CaBER
provides valuable information on a material's physical properties that
rotational rheometers simply cannot provide
Key Features:
The extensional rheological properties of fluids often dominate the
behavior of most fluids in applications like:
Food Products
Consumer Products
Industrial Resins
Coatings and Printing Inks

Industrial Resins
- Relaxation time spectrum
- Constitutive modelling
- Spinnability - Fiber formation
Coatings and Printing Inks
- stringiness / strand formation
- spraying - atomization
- coating - misting, orange peel, leveling
