213 Platinum electrode.
The 213 platinum electrode is an indicator electrode for measuring redox potential.
When matched with tungsten or mercury electrode, it
It can be used for redox potential titration.
Structure:
Type 213 platinum electrode is a bright platinum sheet fused in a glass tube with a lead terminal.
The exposed area of the platinum sheet is about 2×6 mm, and the total length of the electrode is 140 mm.
Use maintenance and precautions:
1.The platinum sheet of electrode must be cleaned in chromic acid solution before use, and then washed with distilled water.
2. If there is oil sticking on the surface of platinum sheet, it should be cleaned with acetone, then cleaned in chromic acid solution and cleaned with distilled water.
