Screw Cap Open Top GC 18mm Headspace Vial, Round Bottom, 10mL 20ml

Headspace vials are made of Aijiren’s borosilicate glass. You can choose from clear or amber colors. Screw-threaded headspace bottles have an average wall thickness of 1.25 millimeters, providing greater reliability as internal pressure increases. The screw headspace vials with 18 mm magnetic caps are suitable for autosamplers that use magnetic transport, while the crimp headspace vials can be used with aluminum caps.

Headspace vials are made of Aijiren's borosilicate glass. You can choose from clear or amber colors. Screw-threaded headspace bottles have an average wall thickness of 1.25 millimeters, providing greater reliability as internal pressure increases. Our headspace bottles meet or exceed OEM standards. The screw headspace vials with 18 mm magnetic caps are suitable for autosamplers that use magnetic transport, while the crimp headspace vials can be used with aluminum caps. The 18 mm screw-neck headspace vials with magnetic screw seals for CTC are new in the headspace market where crimped necks dominate. However, especially for magnetic caps that are difficult to crimp, screw caps are a convenient alternative.

18mm Screw Headspace Vial Advantages:

Mainly used for GC headspace analysis, suitable for headspace analysis of volatile solids and gases. Stores volatile samples and prevents evaporation. They are resistant to high temperatures and corrosion. No risk of incorrect sealing of crimped vials. Easier to close and open, especially since the magnetic cap is difficult to press. Special pre-cut septa (silicone layer is slitted but PTFE remains intact) for safe penetration of the sensitive SPME phase with hardly any coring. Tested and approved by CTC for Combi PAL (Gerstel, Atas, Aijiren), also recommended by Aijiren for the G1888A sampler, by Shimadzu for the AOC5000, and by PerkinElmer for the TurboMatrix autosampler.
