Vial
·independent & ad-free
Vial - The small glass bottle with a rubber stopper that the peptide powder ships in. You draw through the stopper without removing it.
Also called glass vialbottlevials
A vial is a small glass bottle with a rubber stopper secured tightly by an aluminium cap. Peptides usually ship as powder inside it.
Handling
Wipe the stopper with an alcohol swab before each draw; the needle pierces the rubber - the stopper stays on. This keeps the contents sterile and lets the vial be used multiple times.
Confusion with the ampoule
An ampoule is a sealed glass tube for a single draw (snapped open). A stoppered vial, by contrast, is made to be pierced repeatedly.
