Apex Calibration Fluid: Third party okay?

[>>klong<<]

Any reason not to use these calibration fluids to calibrate my Apex probe?

Atlas Scientific pH 7.00 & 10.00 Calibration Solution 125ml - 4oz (Pack of 2)

I use non-Neptune/Apex calibration solution... all fine here. I don't see any reason why calibrating between any two known pH soutions (with the appropriate pH levels like you show here, of course) would cause any issues.
