The tensiometer K100SF is equipped with a highly accurate force measurement system. This enables the extremely small wetting forces of a liquid on a single synthetic or natural fibre to be measured and the contact angle calculated from them.
The LabDesk tensiometer software ensures a completely computercontrolled measuring procedure. As a result of the cooperation the samples no longer require to be changed manually.
The up to 50 samples are first placed in the storage cassette. The series measurement is planned in the LabDesk tensiometer software - thanks to the software module for batch contact angles a matter of seconds.
The sample loader removes the samples in succession and places them in the sample receiver of the Tensiometer K100SF, which then takes over and determines the contact angle fibre for fibre.
The wetted length of each fibre can also be determined automatically.
This requires an additional laser-scan micrometer, which measures the diameters of all the fibres in the storage cassette – with an accuracy ≤1 µm.
The results are transferred to LabDesk and used for the subsequent contact angle measurement series.
