HI7075 Electrolyte Solution 1.7M KNO₃, 0.7M KCl (30 mL x 4)


In stock

HI7075 is a fill solution that contains 1.7M potassium nitrate (KNO3), 0.7M potassium chloride (KCl) for use in fluoride ion selective electrodes. The electrolyte level in refillable electrodes should be topped off 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 fluoride ISE
  • Convenient 30 mL bottles
  • Expiration date and lot number clearly marked on the bottle


The HI7075 1.7M KNO3, 0.7M KCl fill solution is manufactured specifically for the HI4110 double junction solid state fluoride ISE and for the HI5315 double junction reference when used with the HI4010 solid state half cell. This solution is made with reagent grade chemicals, deionized water, certified weight-checked balances, and Class A glassware.
