Eutech EC-620-096 MicroProbe Teflon shaft material combination, MicroTip, 38.1mm stem length, Ag/AgCI reference. Eutech combination electrodes offer the convenience of having the reference and measuring electrodes combined in a single housing. They are offered in a variety of configurations to suit most laboratory and field application needs.

Effective for specific applications the Micro-stem electrode fits into thin stem NMR tubes or small vessels. For harsh use, a durable tough bulb electrode this is resistant to breakage is recommended.

Electrode Construction of EC-620-096:

Calomel Reference (Hg/ Hg2CI2)
Calomel Reference electrodes can give potentials accurate to within 0.01 millivolt. The repeatability and potential stability of such electrodes are superior to those of the Ag/AgCI electrode, although only at a constant and relatively low temperature fluctuation with a temperature limitation of 80ºC. Calomel is recommended for clinical measurement; for samples containing protein, tris buffers; and for high purity water applications.

Single Junction

  • Ideal for general purpose applications.
  • Ag+ ions are in contact with junction and this can cause chemical interaction with sulphur. Not suitable for biological samples or tris buffers.
