Some time back someone wrote in about using packets of calibration fluid and how it might take several packets to get the fluid level high enough in a small container so that the reading could be taken.

I've found a way to do this conveniently with one packet for each pH value used - just cut off the top of the packet and carefully scrunch in down in a small juice glass - one glass for each of the two packets (I'm using pHs of 7.0 and 10.0). Also have a glass of distilled water for dipping the probe in and cleaning it before transferring to the other packet. Convenient,works very well.
