The base unit is the main part of the ProboStat system; all versions compatible with all accessories and methods (except kV version).

ProboStat Description - sample holder cell system

For electrical characterisation etc. at high temperatures and in controlled atmospheres.

  • RT-1600°C

  • Almost any atmosphere (single or dual)

  • Disk (10-24 mm) or bar samples

The cell consists of a base unit with 16 electrical feedthroughs, 4 gas feedthroughs, fixtures for sample support tube, outer tube, spring load, and cooling water.

Samples of various geometries rest on the support tube, is contacted via various electrode connects, and held in place with a ceramic spring load. Additional equipment usually comprise tube furnace with power supply and controller, electrical characterisation (impedance spectrometer, voltmeter, potentiostat, etc.) and atmosphere control unit (e.g. gas mixer).


Versitility

One cell; many accessories, methods, properties:

  • Electrical conductivity vs T, pO2, pH2O, etc.

  • DC, AC, impedance spectroscopy

  • Dielectric properties, loss, etc.

  • Disk, van der Pauw, and bar geometries

  • 2, 3, and 4 electrodes

  • Ionic transport numbers

  • Seebeck coefficient

  • I-V; Fuel cell components and single cells

  • Electrode kinetics

  • H/D isotope effects

  • Electrochemical pumping, gas permeation, etc.

  • Sensor testing

 

The ProboStat measurement cell works with all impedance spectrometers, potentiostats, and multimeters.  Our philosophy is to keep it versatile and with user-replaceable parts (that the user can also manufacture) for good lifetime and long-term economy.

Various standard packages or select a custom package of accessories. Ask us if in doubt or for a suggestion.

Samples

We can manufacture sintered samples of selected materials, with or without electrodes as well as PLD targets. We may also provide certain third-party samples (e.g. SOFC button cells) suitable for ProboStat dimensions.

 

 

 

Power-supply and temperature controller

We re-sell or recommend furnaces or heating mantles for ProboStat from third-party manufacturers.
