A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

The gasket produced by our company has the following characteristics: the gasket is non-toxic; it adopts a non-adhesive bonding process to bond the PTFE membrane and silicon rubber or silica gel together. Chemically inert, resistant to acid, alkali, temperature, and adhesion. At the same time, the elasticity of the silicone rubber or silica gel layer can be used to ensure the sealing performance.

20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption

The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle.
If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.
A PTFE/Silicone with a slitted septum allows for easier needle penetration as well as to release of the vacuum that forms when a large volume of sample is withdrawn from a vial.

Membrane filter is one of the commonly used consumables in laboratories. Common microporous membrane
filter include NY, PTFE, PVDF, MCE, CA and so on.
