In headspace gas chromatography analysis, headspace GC vial play an important role. The quality of headspace vial is related to the success or failure of the experimental results. Aijiren headspace vial are made of borosilicate glass, with safe and stable characteristics.

Screw glass vial refers to a type of container made of glass that has a screw-on cap or closure mechanism. These vials are commonly used for storing and transporting various substances, such as liquids, powders, or small solid samples, in scientific, pharmaceutical, and industrial applications.
The screw-on cap ensures a secure and airtight seal, preventing the contents of the vial from leaking or being contaminated. This feature is particularly important when storing sensitive or valuable substances that require protection from moisture, air, or other external factors.

The 10ml precision threaded headspace vial is used for the screw-top vial and magnetic screw cap of the CTC and TriPlus autosampler. It is convenient to use and does not require any additional tools such as cappers and decappers.

10ml Top empty bottles have a round bottom or a flat bottom.
Both types are suitable for injection but round-bottomed bottles tend to be stronger in storing samples. Therefore, the more reliable work should be the automatic sampler of the round bottom bottle. Round-bottomed bottles also tend to withstand higher pressures and are more suitable for temperature increases and are compatible with applications such as derivatization.The round bottom sample bottle is compatible with most automatic samplers, and the sample arm is convenient for carrying the sample bottle from the tray
The flat-bottled sample bottle can achieve a high level of heating efficiency during manual head space injection and is suitable for certain types of instruments

More convenient, consistent, and safer sealing process compared to crimping (better reproducibility). No risk of inaccurate or inconsistent crimping results. Due to thinner septa suitable for SPME as well as for Headspace. Often used on CTC Combi PAL and identically constructed autosamplers as well as on Perkin Elmer instruments.
