Globex – 20ml Type-1 Head Space (HS) Clear Glass Vials with Flat Bottom Bevel Mouth (Pack of 100 Nos)

20 ml Type-1 Headspace clear glass vials with flat bottom and bevel mouth are manufactured from premium borosilicate glass (Hydrolytic Class-1) to provide excellent chemical resistance, low extractables, and high thermal stability required for headspace GC analysis. The flat bottom ensures stable positioning in autosampler trays, while the bevel crimp mouth design supports secure, uniform sealing with 20 mm aluminum headspace crimp caps and septa, ensuring hermetic closure during heating and sampling.

These vials are engineered for high-temperature and pressurized headspace applications where sealing integrity, sample containment, and reproducibility are critical. The clear glass construction allows easy visual inspection of sample volume and condition.
