Description: 18mm screw headspace vials are suitable for headspace analysis of volatile solids and gases. Mainly used in gas chromatography analysis for headspace analysis. Store volatile samples to prevent sample evaporation.   Features:

1. Available in clear and amber USP1 borosilicate glass with screws and crimp top.
2. The round bottom bottle distributes the internal pressure generated under the high temperature of the glass surface, and it is easier to handle the vial being lifted from the tray by the robot arm.
3. The screw-head empty bottle has 18mm Magnetic cap, which is suitable for autosampler using magnetic transportation, while crimping the top bottle to be used with aluminum cap
