Notes for the bench.
Educational primers on purity, handling, and the compounds we list. These notes are not protocols for human use.

Reconstituting a lyophilised vial
Solvent choice, wall-wetting, and why you swirl rather than shake: a laboratory handling note, not a dosing guide.

Storage, temperature and shelf life
Lyophilised material prefers the freezer and the dark. Reconstituted solutions are a different, shorter problem.
