pH Probe KCI Storage Solution

Letting pH probes dry out between uses is a sure-fire way to shorten the lifespan of your pH probes and pens. Prevent your probes from drying out by using this solution as directed:
For pH pen: Place 3-5 drops of solution into the round hole of the pH pen storage cap each week. Place storage cap onto pH pen.
For pH probes: Place enough solution into the probe storage cap to fully submerge the pH probe tip.

Hydrate pH pens and probes monthly by submerging the pH probe tip or pH probe pen in solution for 24 hours

Ingredients: Potassium chloride (KCI), water
