Sample Cells Overview

The sample cells used in our dielectric, conductivity and impedance spectrometers are shown below. For details, click on the cell headers.

sandwich

In all cells, the sample material is prepared between additional external parallel plate electrodes BDS 1301 or BDS 210X in order to form a sandwich capacitor as shown below. For the measurements, the sandwich capacitor is mounted between the cell electrodes.

For solid samples, the electrode spacing is adjusted by the sample thickness, for liquids or powders, additional spacers or the liquid cell BDS 1308 may be used.

All cells except the high temperature cell are compatible with all temperature control systems
