I received a Milwaukee ph meter (MW102) for Christmas. I am ashamed to say I have not gotten to play with yet but hope to rectify that soon! My question is around the buffer solutions that came with the meter. They are in small foil bags, similar to a capri sun. They do not appear to be resealable. Does anyone have tips/tricks on how to manage the buffer solutions that come in this packaging? Should I buy some small plastic bottles and transfer the solution to them? Can I fold it over and use a clip or clothespin to seal it up? I'm hoping to hear they are not "one and done".
