Potassium Nitrate Solution, 10%, Reagecon™

Use in the outer chamber of double junction pH electrodes when using media that contains copper, lead, silver or mercury ions. Potassium Nitrate Solution, 10%, Reagecon™ is a standard solution of KNO₃. It is also used as a standard in the testing of dairy products.

Brand:  Reagecon EFSKNO

Product Code. 11758455

Description

The glass layer and reference junctions of pH electrodes need to be kept moist when not in use to remain operable and functioning at optimal levels. Potassium Chloride cannot be used with media that contains Hg⁺⁺, Cu⁺⁺, Ag⁺ or Pb⁺⁺ ions, as they form insoluble precipitates with Cl^– that will block the diaphragm. Potassium nitrate is a double junction bridge solution that can be used in this case.
