Less than a full dose is okay. Add reactant at a ratio of 5%. I use disposable pipettes for that.
Recapped, the reactant is good for 30-45 days. If it starts to crystalize inside, it is bad.
As Z7098 gets older, you'll find the solids want to settle to the bottom. I like to give it a stir with a fresh tongue depressor to recombine it, or a shake.
