A vial is a small glass or plastic tube which is used to store medicines like capsules, liquids, and powder. The word Vial was derived from the Greek word ‘Phial’ which means a broad flat container.Vials are also known as phial or flacon. These have a tubular or bottle-like shape with a neck. The volume of liquid by the neck is known as headspace. Vials are generally used in labs for chromatography which is a technique for separation of a compound mixture.
Screw Cap Vials are universal. A mechanical force is applied to them that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.
