What is a suitable disk sample size for use in the ProboStat cell?

Sample diameters that can be used in the ProboStat are normally between 10 and 24 mm. Standard sample diameter (and support tube diameter) is however 20 mm. Please note that for 4-point conductivity measurements on disk samples (van der Pauw method) the sample diameter needs to be 20-24 mm.

A new setup has been developed on customers request. It is specialized for measurements on disk samples with diameters 25 to 60 mm.
