Very simple. Cut open the top of the packet with scissors. Spread the top open, make a V-shaped bend in the side of the top of the packet, pour the reagent powder down the "V" into the glass vial.

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.
