Pharmaceutical Glass Vial Knowledges
- Jul 23, 2017 -

Pharmaceutical glass vial (also known as a phial or flacon) is a small glass vessel or bottle, often used to store medication as liquids, powders or capsules. They can also be used as scientific sample vessels.

Modern vials are often made out of plastic or sometimes glass. There are often used as storage for small quantities of liquid used in medical or molecular biology applications. There are several different types of commonly used closure systems. For glass vials, options include screw vials (closed with a screw cap or dropper/pipette), lip vials (closed with a cork or plastic stopper) and crimp vials (closed with a rubber stopper and a metal cap). Plastic vials, which can be moulded in plastic, can have other closure systems, such as 'hinge caps' which snap shut when pressed. These are sometimes called flip-tops or snap caps.

The bottom of a vial is often flat, unlike test tubes, which have usually a rounded bottom, but this is often not the case for small hinge-cap or snap-top vials.
