Coaxial-Shear Cold Finger cCF6 - the 'Specialist' in the lab
Measure wax deposits under shear conditions
The laboratory device of the Coaxial-Shear Cold Finger cCF6 examines wax deposits and the effectiveness of wax and parrafin inhibitors. The 6 measuring stations in a water bath available for this purpose. All fingers can rotate to measure the wax deposition under shear conditions.
The pneumatic lift makes operation much easier. Lifting the head section and changing the sample or removing the measuring sleeve can be done safely in seconds.
The Coaxial Shear Cold Finger cCF6 is a compact, easy-to-use and safe measuring device. It achieves reproducible results by providing the same conditions for all 6 measuring stations for accurate analysis. The modular design and the expandable temperature and pressure ranges enable maximum flexibility.
All important features of cCF6
- Rotating fingers to measure wax deposits under shear conditions
- 6 measuring places for simultaneous tests
- Removable sleeves for easy weighing and cleaning
- Precise finger and bottle positioning for accurate results
- Lift system for easy use
- Almost closed water bath ensures low evaporation

Short story about Coaxial-Shear Cold Finger cCF6
With the Coaxial-Shear Cold Finger cCF6, the classic design of the Multi-Place Cold Finger CF6 with water bath is extended to include shearing. For users, this means greater convenience in handling and more accurate results.
Based on the proven PSL cold finger measuring technology and a new type of lift system, the 6 sample units are held separately from each other. This means that different chemicals or sample concentrations can be measured in parallel and the samples can also be individually pre-tempered. The cooling fingers can be positioned to match the size of the sample bottle in order to measure the temperature exactly where the wax deposits occur.
The CF6 has been designed to be easy to use and to need a small space in the laboratory.
The removable sleeves allow the measurement of wax deposits over time as well as easy weighing and cleaning.

Measurement Principle
A crude oil sample is stirred and kept above Wax Appearance Temperature (WAT). A cooled zylinder element – so called ‘cold finger’ – is immersed in the sample, providing a cold surface, where the waxes of the crude oil shall deposit.
An integrated magnetic stirrer is providing a gentle circulation to ensure that all of the sample gets in touch with the cold finger surface. The amount of wax that deposits at this surface at given temperature in ratio to the total amount of sample is an indication of potential amount of wax deposition as well as, related to a blank test, for the efficiency of a wax inhibitor (WI).
Different then with a ‘classical’ Cold Finger, a well-defined shear can be applied to the finger surface by rotation of the finger. By use of different rotation speeds the shear condition that applies during production on the pipeline wall can be simulated.
