How to store probes?

[almost]

I change my set up and now my second aquarium become a refugium in the display tank.

So, I have some probes (salinity, reedox, conductivity) that I am not using any more.

How can I store them so I will have them as backup?

Any special fluid?

Salinity and conductivity probes are the same or similar and can be stored dry
(Platinum or Graphite electrodes to measure resistance; no filling)
ph and Redox should be stored in 1-molar KCL solution
(it´s always a good idea to store the cap of probes; glass probes, filled with KCL)

Thnaks Wirus!

Will clean my Salinity & conductivity and store them away.

What is 1-molar KCL solution?
Should I go to a drug store to make one for me?

What is 1-molar KCL solution?
Sorry, description was not really correct, chemical formula is KCl, better known as potassium chloride (http://en.wikipedia.org/wiki/Potassium_chloride)

Translation from german Wikipedia (english article don´t have that note):


Elektrolyte- und store solution for ph- and redox probes (nearly saturated solution with 3 mol/l KCl solution). Due the identical ionic mobility of potassium- and cloride ions this solution has no electric (chemical; galvanic) potential.

Your dealer of probes also should have that solution.

Additional hint: They also should have a Pepsin solution for cleaning the probes.

Many Thanks Wirus!
