250 ul Micro-Insert, 31x5mm for 8-425 Vials, Flat Bottom, 100/Pk - CV2049
Integrated insert construction in Tisch CV2049 micro-volume vials ensures the needle reaches the sample cone reliably, minimizing analyte waste in limited-quantity workflows. Integrated design eliminates the air gaps and misalignment inherent in loose-insert configurations, reducing injection volume variability in quantitative trace-level methods. Together, reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
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. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.

- Stability Study Samples - Micro-volume design accommodates the small aliquots pulled from time-point stability testing protocols.
- Method Development - Reduced sample requirement per injection accelerates method optimization when reference standards are quantity-limited.
- 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.
- Precious Sample Recovery - Integrated insert eliminates the dead-volume losses that compromise quantitation of irreplaceable research specimens.
