Overview
The SI1302 Microcathode Oxygen Electrode is used with all of our respirometry research products. It is a Clark-type polarographic electrode, with a 22 µm diameter platinum cathode and silver/silver chloride anode, connected by a buffered potassium chloride electrolyte solution.
Functionality
Oxygen permeates through the membrane of the electrode, which is either a polypropylene (PP) membrane or a fluorinated ethylene propylene (FEP) membrane. The oxygen is then reduced at the cathode, resulting in a concomitant increase in current.
This current is coverted through sophisticated software to calculate the concentration of dissolved oxygen within the sample and, where applicable, the rate of change of oxygen within the cell or chamber.
