0.6 M K2SO4 & 20 mM KCl
Usually, electrode filling solution is made in 250 mL batches.
Add deionized H2O to 26.141 grams of K2SO4 and 0.373 grams of KCl to obtain a final volume of 250 mL of solution.
Heat the solution on the mixer, giving it ample time to fully dissolve (~ 30 minutes).
Let the solution cool and filter it by drawing the solution into a large syringe, placing a luer-lock filter on the end of it, and pressing the solution out of the syringe through the filter and into a new container.
Repeat if necessary. Do NOT draw the unfiltered solution into the syringe with the filter already on it. The filtered particles will be on the wrong side of the filter and will re-enter the solution.
