Vial
Also known as: glass vial · stoppered vial
The small sealed glass container, capped with a rubber stopper, that peptides are supplied and reconstituted in.
A vial is the small glass container in which a lyophilised peptide is supplied. It is sealed with a rubber stopper and an aluminium crimp cap, allowing a needle to enter without exposing the contents to air.
Solvent is injected through the stopper to reconstitute the powder, and the finished solution is drawn back out the same way. The stopper is wiped with alcohol before each entry as part of sterile technique.
