Can you re-use the calibration fluid that comes with your ph probe? Or are they use once and throw away?
Thanks

If you want to have acurat results: Use always new test fluid and also flush in between with destilated water.
I use a small test tube (not far bigger than the probe) and need only 1-2ccm of test fluid, so the test fluid bottle is good for years
So, it is ok once opened and exposed to air? Thanks.
You don't have to use a new bottle of fluid each time you calibrate. The best is to fill a little fluid into another flask for each calibration to avoid
that you have to put the probes into the original bottle. This way, the fluid will last for a longer time.
