The 20mm 20ml Crimp Top Headspace vial has a 20mm outer diameter, which is the standard size for crimp-style headspace vials. The 20ml capacity refers to the volume of the vial, meaning it can hold up to 20 milliliters of liquid or gas sample. These vials are typically made from high-quality borosilicate glass. Borosilicate glass is chosen because it is resistant to chemical reactions and can withstand high temperatures, making it ideal for containing volatile samples without contamination. 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.
