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

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

These vials with flat bottom are designed for high-temperature headspace applications where sample integrity, pressure resistance, and reproducible sealing are critical. The clear glass allows visual inspection of sample condition and volume.
