Sounds the same then, although hopefully the vial is different with this one. With the one I had the opening was very small and it was tough to get all the powder into the vial without spilling at least some.

I want to do this but I am swamped with work, travel etc. It is on my list of things to do. I'd also like to make a known standard from potassium phosphate and RO water to test the meter against.

That would be very interesting. If you do get around to it I would like to see the results.
