pH solution

[teesherv]

I have envelopes of dried chemicals for pH calibration (nine of each pH4 and pH7) and 8oz (minus a couple of mL) of storage solution. Just bought last month but not gonna use them.
Free to whoever wants to pick up. Located in Elk Grove, CA.

Willing to ship the packets? Don’t need the wet solution.

Edit: sorry, disregard that. Clicked the pic and noticed it’s not 7.0 solution
