Eutech EC-620-131 Glass Body, Polymer, Open Pore pH Electrode.

Electrode Construction of EC-620-131:

Open Pore Junction
About 200 times larger than ceramic junctions, ensures increased electrolyte flow for stable junction potential.

Double Junction
A double junction reference is constructed with an Ag/ AgCI inner chamber and a chemically compatible reference solution in the outer chamber. It is recommended for samples containing organic compounds, proteins, heavy metals; and other compounds that interact with silver, such as bromides, iodides, cyanides and sulfides.

  • Prevents interference between the inner fill solution and sample.
  • Electrolyte is free of Ag+ ions. Suitable for use with biological samples. Can be used in place of calomel reference electrodes.
Glass Body
  • Glass withstands high temperature of 100ºC or more.
  • Resistant to corrosive materials and solvents.
  • Brittle.
  • Ideal for laboratory use and is easy to clean.

Sealed Design
No refill hole. The reference electrolyte is usually gel.
Replacement of the electrode is necessary when it gets contaminated.
Virtually no maintenance is required.
