HI7072L is a 1M KNO3 electrode fill solution for use in double junction and ion selective electrodes. The electrolyte level in refillable electrodes should be checked before performing any measurements. If the level is low, refill with the proper electrolyte solution to ensure optimum performance. This simple maintenance helps guarantee adequate head pressure to promote the flow of reference electrolyte into the sample being measured.

  • Fill solution for double junction and ion selective electrodes
  • Air tight bottle with tamper-proof seal to ensure quality
  • Clearly marked bottle with expiration date and lot number

Details

The HI7072L 1M KNO3 (potassium nitrate) electrode fill solution is chloride free. It is mainly used as a reference fill solution for Bromide, Cadmium, Chloride, Cupric, Cyanide, Iodide, Lead/Sulfate, and Silver/Sulfide electrodes. It can also be used as an alternative to 3.5 M KCl (potassium chloride) fill solution used in double junction refillable electrodes when taking pH measurement of samples that have heavy metals such as silver, lead and mercury. These heavy metals can react with the 3.5M KCl solution to form insoluble chloride salts. Any precipitation in the the liquid junction will interfere with the reference potential resulting in erratic readings.

Hanna’s double junction system has two junctions, only one of which is in contact with the sample as shown in the figure below. The likelihood of clogging the outer junction is ordinarily reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free” to prevent precipitate from forming that will clog the junction. The HI7072L electrolyte solution is also “chloride-free” which minimizes precipitation from solutions containing heavy metals. The HI7072L ensures optimum measurement performance from your pH electrode.
