Thermo Scientific crimp top vials for HPLC and GC are available in 8mm, 11mm, or 13mm crimp border diameter in clear and amber glass and plastic. Microsampling options for small-sample-volume injections include one-piece microvials and standard inserts added to crimp top vials. Crimp vials are sealed with aluminum caps with septa using crimper and decrimper tools (manual or electronic). The vial selected depends on your sample size and instrument compatibility (see autosampler compatibility chart).
Snap vials sealed with snap caps are easy to apply and remove without the need for crimping or de-capping tools. These chemically inert polyethylene caps are an economical choice for most routine HPLC applications but have low sealing property. Snap caps have a large open area allowing easy needle penetration across the entire vial opening. Aluminum crimp caps can also be used to seal snap-it vials (using a crimper).

Consider Thermo Scientific 2 mL SureStop Screw Top Vials with AVCS Caps as a secure alternative to crimp top vials. These specially designed screw top vials create an optimal seal with performance data similar to traditional crimp vials. See this technical note for performance data. Screw top vials are convenient and eliminate the need for crimping and decrimping tools.
