Bacteriostatic water, lyophilised vs reconstituted storage, and research supplies.
Amber vials and "keep away from light" are everywhere but the specifics never are. What I understand: photodegradation is driven mainly by certain residues (tryptophan, tyrosine, …
not the exciting part of this hobby but the part that decides whether anything else works. stuff that comes up repeatedly: alcohol swabs, the right syringes, a sharps container, s…
Small distinction that causes real confusion. Expiry date: set by the manufacturer for the unopened product stored as directed, backed by stability testing on that product in that…

Short version of something that keeps getting mixed up. Storage advice for the powder does not transfer to the solution and vice versa. Different physical states, different failur…
There are really two storage questions and mixing them up is where most of the confusion comes from. Powder (lyophilized, not mixed yet): freeze drying removed the water that hydr…
Comes up constantly and the answers are usually half right, so here's the full version. Bacteriostatic water is sterile water with about 0.9% benzyl alcohol as a preservative. Ben…
