pH Electrode Storage Solution

[Cambrinus]

Hi all,

My pH meter came with 2 buffer fluids and a storage solution.
After use I would put a drop of the storage solution in the protective cap and put the pH meter away till next time.

Now I'm running low on this storage solution.
Anyone knows where I can get this? or do I need to use it in the 1st place? Can I use something else?

Cheers,

You can use the pH buffer solutions to do the same thing. I never used storage solution with mine only buffer solutions.

Interesting. That's good to know.

The important thing is to make sure the electrode never dries out. My probe has a bottle attatched to it. Probe goes though hole in bottle and is stored upright.

You can buy storage solution cheaply on the bay.

Do not store in pure water as you will ruin the cell.

We have the same set up as Will in the brewery

So is storage solution preferred over buffer fluid?

Is not that cheap I thought... £15  or am I looking at the wrong thing?

I have deionised water in the cap of my ph pen. Is this okay?

It all depends on the technology! If its a glass electrode then the answer is no!

A simple storage solution is 3M Potassium Chloride solution:

Disolve 22 grams of Potassium Chloride in 100 mL distilled(ro water) and use this.

I THINK? MAYBE? you could use 18 gms of table salt instead. (would give 3M NaCl)

But KCl is dead cheap and can be found as a major ingredient of "Lo-Salt"

[RichC]

Hi Will I need some of that stuff too. Should I just substitute Lo-salt for KCL or should I go into the pharmacy and buy some KCL-or would they look at me funny?

[Cathal O D]

Looking for some KCL here too. I tried "borrowing" some from the lab at work but its not as easy ad I thought.

€8 a kilo to Parcel motel BUT more like €18 a kilo delivered to dubland

So why not get a kilo for 8 + 3.50 and then spilt it up 10 ways 100 gms will last a looong time
