High-Quality 18mm 20ml Screw Headspace Vial Supplier
Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. 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 material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.

Feature
1. 20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption
2. The 20ml precision threaded headspace vial is used for the threaded vial (10ml+20ml) and magnetic screw cap of CTC and TriPlus autosampler.
3. It is convenient to use and does not require any additional tools such as a capper and disappear.
4. The magnetic screw cap can be widely used in various SPME and headspace analysis.
Matching cap and septa:
The 18mm septa uses only the highest quality materials to ensure proper function, and is especially suitable for gas chromatograph applications, ensuring that the septa will not fall into the sample vial during sample injection. The septa are made of PTFE/silicone fusion, are made of TFE/silicone fusion, and have excellent inertness and can be used for multiple injections. The thickness of the septum is 1.5mm.
The screw headspace vial caps combine innovation with time-saving convenience, precise manufacturing tolerances, and a controllable manufacturing environment. The bottle cap produced by this patented method truly combines the septum and the cap at the molecular level to avoid excessive evaporation and keep the sample bottle properly sealed.
