Snap Top Vials

Snap Top Autosampler Vials

Chrom Tech snap top autosampler vials are designed for laboratories that require speed, consistency, and convenience without compromising seal integrity. Available in both Snap Seal and Snap Ring designs, these vials provide a secure closure without the need for crimping tools—streamlining daily workflows in high-throughput HPLC and LC/MS environments.

Manufactured in the standard 11 mm snap top format, these vials feature a wide-mouth opening that simplifies manual and automated pipetting while providing a larger target area for autosampler needles. This design helps reduce mis-injections, improves needle alignment, and supports consistent sample access across runs.

Chrom Tech snap top vials are available in clear glass, amber glass, and polypropylene to support a broad range of analytical applications—from light-sensitive compounds to protein or LC/MS-sensitive samples. When paired with Chrom Tech snap caps, the system delivers a reliable, repeatable seal suitable for demanding chromatographic conditions.
