Vial
Encyclopedia
A vial is a relatively small glass
vessel or bottle
, especially used to store medication
as liquids, powders or in other forms like capsules. They can also be sample vessels; e.g., for use in autosampler devices in analytical chromatography
.
The glass can be colourless or coloured, clear or amber. There are different types of closure systems, i.e., screw vials (closed with screw cap or dropper/pipette
), lip vials (closed with cork or plastic stopper
), crimp vials (closed with a rubber stopper and a metal cap). A vial can have a tubular shape or a bottle-like shape with a neck. The volume defined by the neck is called the "headspace". The bottom is usually flat unlike test tube
s which have usually a rounded bottom. Modern vials can be made of plastic (e.g. polypropylene
). These can have other closure systems like a flip-top/snap cap.
The small bottle shaped vials used in laboratories are also called bijou or McCartney's bottles. The bijou bottle tends to be smaller; around 10ml.
