Product information »Cleaning solution with thiourea - Diaphragm cleaner«

Over time, the display of pH and redox electrodes can be increasingly sluggish. In addition to the inevitable aging of the electrode itself, various deposits from the test sample, which affect diaphragm and glass electrodes, also contribute their part.

Due to the sulfides that are almost continually present in biological systems and the traces of silver chloride in the electrolytes, silver sulfides (blackening), which are almost insoluble, can form in the electrode's diaphragm. As a result, the charge exchange with the inner reference electrode becomes increasingly more difficult.

Thiourea forms exceptionally stable complexes with silver ions, so that even the silver sulfides, which are barely soluble, are dissolved after some time. First, place the electrode into the cleaning solution until the diaphragm is destained, then condition it for about 15 minutes in one of our potassium chloride solutions, finally re-calibrate it.
