**Autosampler Vials & Low‑Volume Inserts **

Autosampler vials and low‑volume inserts are essential components for accurate sample containment, injection, and reproducibility in chromatography workflows. This category includes crimp‑top, screw‑top, snap‑top, push‑top, headspace, specialty, and plastic vials, as well as low‑volume inserts and vial‑insert management systems used in HPLC, LC‑MS, GC, CE, and headspace analysis.

Vials are available in a wide range of formats, materials, surface treatments, and volumes to accommodate different analytical requirements, instrument configurations, and sensitivity levels. Proper vial selection helps minimize sample loss, reduce adsorption and evaporation, and support consistent autosampler performance across routine and advanced methods.

This category includes vials and inserts from multiple performance tiers, allowing laboratories to select solutions that match their analytical demands:

• Crimp‑top vials with serum finishes designed for secure sealing with aluminum crimp caps

• Screw‑top vials available in multiple thread sizes and surface finishes for flexible, repeatable sealing

• Snap‑top vials designed for rapid sample preparation where volatility is low

• Headspace vials engineered for pressure‑ and temperature‑resistant sealing in headspace GC workflows

• Low‑volume inserts and vials used to improve recovery and injection accuracy when sample volume is limited

• Plastic vials formulated for PFAS analysis and bio‑compatible applications

• Specialty and push‑top vials designed for non‑standard configurations and legacy autosampler systems

Autosampler vials and inserts are offered across performance tiers, differentiated by glass composition, surface chemistry, and cleanliness:

• RSA‑Pro X™ surface‑treated vials and inserts with hydrophobic, adsorption‑resistant surfaces

• RSA™ reduced‑surface‑activity glass with silanol‑free, slightly hydrophilic characteristics for highly reliable performance

• AQ™ vials manufactured from certified Type 33 borosilicate glass for low extractables and analytical consistency

• MICROSOLV™ brand pharmaceutical‑grade vials produced from N51A borosilicate glass

• BASIK™ economical vials designed for general laboratory use

Low‑volume inserts, vial kits, and management systems such as U‑2D™ micro‑sampling formats are also included, supporting trace analysis, limited sample availability, and high‑throughput workflows.
