Screw Thread Vials
Screw Thread Autosampler Vials
Chrom Tech’s 9 mm wide-mouth screw thread vials are our recommended format for most HPLC and LC/MS workflows. With a 40% larger opening than 8-425 vials, they simplify pipetting and routine handling while retaining broad autosampler compatibility. Options include clear and amber Type I borosilicate glass, polymeric formats, and mass-spec–certified glass. Pair with preassembled screw caps for reliable, leak-free sealing.
