what belongs on a research supplies list, boring edition
not the exciting part of this hobby but the part that determines whether anything else works. things that come up repeatedly in what ive read: alcohol swabs, appropriate syringes,…
Storage, Reconstitution & Supplies
Bacteriostatic water, lyophilised vs reconstituted storage, and research supplies.
Expiry date vs beyond-use date — not the same thing
Small distinction that causes real confusion. Expiry date is set by the manufacturer for the unopened product stored as directed. It's backed by stability testing on that product …
how do people handle temperature when travelling
the storage threads all assume a fridge you control. what do people do when that isnt available for a few days
Is reconstitution solution the same as bacteriostatic water?
Short answer: sometimes, and you can't tell from the name. "Reconstitution solution" describes a purpose, not a composition. Products sold under that description vary — some are b…
Does bacteriostatic water itself need refrigerating?
Separating two questions that get merged. The bacteriostatic water on its own: generally stored at controlled room temperature. It doesn't require refrigeration. Manufacturer labe…
How reconstitution actually works, step by step, and the two places people go wrong
The mechanics, described rather than prescribed. The process as generally described in the literature: 1. Let a cold vial come to room temperature first. Adding liquid to cold pow…
Bacteriostatic water vs sterile water — when does the difference actually matter?
Both are sterile at the point of opening. The difference is what happens afterwards. Sterile water has no preservative. Once opened it has no ongoing protection. Bacteriostatic wa…
Lyophilised vs reconstituted storage — two completely different problems
Short version of something that keeps getting mixed up. Storage advice for the powder does not transfer to the solution, and vice versa. They're different physical states with dif…
Peptide storage — fridge, freezer, or neither, and why the answer changes after reconstitution
There are really two storage questions and conflating them is where most of the confusion comes from. Lyophilised (powder, unreconstituted). Freeze-drying removes the water that h…
Bacteriostatic water — what it actually is, and why it isn't the same as sterile water
Comes up constantly and the answers are usually half right, so here's the full version. Bacteriostatic water is sterile water containing about 0.9% benzyl alcohol as a preservativ…
