Microvials

Microvials are small-volume chromatography vials designed for samples where only a limited amount is available or where maximum recovery is important. They help concentrate the sample at the base of the vial so the autosampler needle can access more of the available liquid, reducing residual volume and helping to minimise sample waste. Crawford Scientific offers microvials for HPLC, GC and related analytical workflows, including microsampling, trace analysis, low-volume methods and sample-limited applications.

Different microvial formats are available to suit a range of recovery needs. High recovery vials feature a shaped internal base to improve access to small sample volumes, while total recovery vials are designed to reduce residual volume as much as possible. Micro-V vials use a narrow, V-shaped profile to guide the sample to a single point for efficient extraction, and fixed-insert vials include a fused insert within the vial body, removing the need to assemble separate inserts. These options provide flexible solutions for small-volume chromatography applications where reliable sample recovery is essential.
