BluelabCalibration Solution pH 4.0, 7.0 and 2.77 EC Conductivity Solution, 500 ml Each

Q: What is the difference between kcl storage solution and 2.77 ec conductivity standard solution?? both of them contain kcl and water..

It is actually 27.7 the description is a typo. Bluelab Calibration Solution pH 4.0, 7.0 and 2.77 EC Conductivity Solution, 500 ml Each. Look at the label on the bottle.

Q: How long does the 7.0 and 4.0 solutions last once opened? I assume you pour out a little each time you calibrate. Is 70 F a good temp to store it?

I have had mine since February and I keep it under the sink in about70°. It seems to be just fine I also reuse my calibration solution as I am careful not to contaminate it
