Jeff: I suspect that Kenco has you storing pH electrodes in buffer 4. I
probably should have mentioned that above. First choice, storage solution.
Second choice, buffer 7 or buffer 4. It depends upon which reference you
read. The Fisher Scientific FAQ on pH electrodes says in one place to use
buffer 4 for long term storage, in another place it says use buffer 7. I
think it matters little as long as you don't use straight water.
Personally, I use buffer 7 because I have a big bottle of that and a small
bottle of buffer 4.................Interesting rationale we humans use
Below is the link to their FAQ for those interested. If you want to know
anything about pH probes, this is probably the definitive place. I don't
personally know what type of probe the kenco uses, but I betcha that it's
covered in this:
