250ul Micro-Insert, 29x5.7 mm for 9mm Vials, Mandrel Interior & Polymer Feet, 100Pk - CV2042
Micro-volume autosampler vials from Tisch feature integrated conical inserts engineered for maximum sample recovery from limited-volume specimens. Conical insert geometry channels the sample toward the needle tip, maximizing recovery from volumes as low as 150µL without repositioning or specialized autosampler settings. Stringent manufacturing tolerances across vials, caps, and septa ensure that every component in the sample containment chain performs to the specifications modern analytical methods demand.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. Bonded insert construction gives you the consistent needle-to-sample positioning that loose inserts cannot guarantee, improving injection precision across your full sequence. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.

- Method Development - Reduced sample requirement per injection accelerates method optimization when reference standards are quantity-limited.
- Precious Sample Recovery - Integrated insert eliminates the dead-volume losses that compromise quantitation of irreplaceable research specimens.
- Stability Study Samples - Micro-volume design accommodates the small aliquots pulled from time-point stability testing protocols.
- Metabolite Identification - Low-volume capability supports injection of concentrated extracts without dilution-related sensitivity losses.
- Pediatric Bioanalysis - Reduced dead volume enables accurate injection from the sub-milliliter specimen volumes typical in pediatric studies.
- Trace-Level Quantitation - Conical micro-insert geometry channels limited sample volume to the needle tip for maximum analyte recovery.
