Fill the meters cap with the solution and place it in there. You always want to have the solution in the cap **Q: Do the bottles have a lot number and expiration date imprinted?** A: Yes, they have an expiration date printed- and amazon ask for them before they are allowed to be sent into the fba program. **Q: What ph does this solution keep a ph/ec/tds meter's electrodes? should one be able to use their meter, immediately from the storage solution?** A: The ph storage solution is right around a 4 ph. I always re-calibrate with 4.01 & 7.01 after removing from the storage solution. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The storage solution is the storage solution *by L***S on August 11, 2014* I've ordered this before for use on my pH meter - they're expensive and well worth taking care of - and I've reordered it at least once, since, and will again, I'm sure.
