Ph meter storage solution recipe.
It is easy to create your own storage solution if you have the right stuff.
We recommend that you store your electrode in a solution of 4 m kcl.
2 while the probe is soaking prepare a batch of new storage solution.

10 grams of solid kcl dissolved in 100 ml of ph 4 buffer.
For long term health of your elctrode use ph storage solution.
Firstly you should make sure you always keep your ph electrode moist the best solution to submerge the probe for long and short term storage is 4m potassium chloride solution kcl.
If you don t have that an alternative would be to use distilled water as the starting point for your storage solution.
Expired solution is perfect.
The filling solution in refillable electrodes should be filled up to but not past the refill hole.

It is a mixture of potassium chloride postassium hydrogen phthalate silver nitrate and sodium hydroxide.
Any ph 4 buffer mixture works well but use only kcl for the salt other salts do not work.
When potassium chloride solution is not available revert to ph 4 or 7 buffer solution.
An ideal start to your storage solution is to start with a bottle of ph 4 0 calibration solution.

Ph probe storage solution recipe.
1 let the ph electrode soak for 4 8 hours in an hcl solution between 0 1 and 0 5 m.
2 while the probe is soaking prepare a batch of new storage solution.
Make sure the refill hole is left open when measuring to ensure that the fill solution flows properly through the reference junction.
