Design
There are several different types of closure systems, including 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 can have other closure systems, such as flip-tops or snap caps. A vial can be tubular, or have a bottle-like shape with a neck. The volume defined by the neck is known as the headspace. The bottom of a vial is usually flat, unlike test tubes, which have usually a rounded bottom. The small bottle-shaped vials typically used in laboratories are also known as bijou or McCartney's bottles. The bijou bottle tends to be smaller, often with a volume of around 10 milliliters.
