manufacture septums in different sizes and colours.
Septums are rubber stoppers which seal flasks or bottles.
They give an air-tight seal, preventing the ingress
of the atmosphere, but are able to be pierced by sharp
needles. A rubber septum consists of a rubber disk
used to seal a vial or other device. A syringe needle
pierces the rubber septum for the purpose of injection
and, on withdrawal, the elasticity of the septum ensures
that the hole reseals. Septums are used when a substance
either needs to be injected into or pulled from a
vial then re-sealed.
