Screw top vial and cap kits are pre‑matched autosampler vial and screw cap combinations designed to support reliable sealing, ease of use, and reproducible performance in chromatography workflows. These kits are widely used in HPLC, LC‑MS, GC, and CE applications, where consistent cap‑to‑vial compatibility is essential.
The vials included in this category are manufactured from glass or plastic materials and are available in a range of shapes, volumes, and surface treatments to meet diverse laboratory requirements. Screw top vials are among the most commonly used autosampler vials due to their flexibility, repeatability, and compatibility with a broad range of analytical instrumentation.
Each kit pairs compatible screw caps with vials, offering multiple septum types and cap color options to support different injection styles, analytical sensitivities, and instrument requirements. Proper matching of vial thread design and pitch with the appropriate screw cap helps minimize leaks, evaporation, and misalignment during sample injection.
Screw top vial and cap kits are supplied in protective clamshell containers, supporting organized storage and clean handling on the laboratory bench. These kits simplify ordering, inventory management, and distribution while maintaining consistent performance across routine and advanced chromatography workflows.
This subcategory includes screw top vial and cap kits offered across multiple performance tiers, including standard configurations, center‑draining designs, limited‑volume vials, and surface‑treated options for sensitive analytes. Selection of the appropriate kit depends on sample volume, analytical method, and instrumentation requirements.
