Select from our portfolio of high-quality glass 8mm crimp/snap top vials that are ideal low-volume sample vials for 6mm, 7mm and 8mm autosampler trays. Choose from flat or conical base to maximize recovery needed for small-sample injections. Re-usable sleeves support the crimped, sealed vials in the correct position in autosampler carousels or in racks and allow movement of the vials as a unit to injection positions in both GC and HPLC autosamplers.
