The YSI Zobell Solution is a reference solution that is used to characterize redox potential cells. This product is packaged in dry form and must be reconstituted before use. Each amber bottle contains 75% Potassium Chloride, 14% Potassium Ferrocyanide Trihydrate, and 11% Potassium Ferricyanide by weight.

  • A convenient temperature chart with corresponding ORP values is on the side of the container for simple calibration value inputs
  • Concentrated power makes 250mL of the calibration standard
  • Plastic bottle (250mL)

To reconstitute the solution, add deionized or distilled water. The volume of water required depends on the part number purchased. Add 250 mL,  +/- 5 mL, which typically reaches just below the bottom of the bottle’s neck. The label should be marked to indicate the correct expiration date.

The reconstituted solution has a maximum shelf life of 6 months. The shelf life of an unopened bottle is 5 years; it should be stored below 40°C.
