Screw Top 9mm Plastic Clear 0.3mL HPLC Autosampler Vials w/ Micro-Insert, 100/Pk - CV1981
Integrated insert construction in Tisch CV1981 micro-volume vials ensures the needle reaches the sample cone reliably, minimizing analyte waste in limited-quantity workflows. Base-bonded insert construction prevents liner displacement during autosampler needle descent, maintaining consistent needle-to-sample distance across the full injection sequence. Reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
Matching the right vial, cap, and septum configuration to your instrument and application ensures that sample containment never becomes a source of analytical uncertainty. Bonded insert construction gives you the consistent needle-to-sample positioning that loose inserts cannot guarantee, improving injection precision across your full sequence. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.

- Stability Study Samples - Micro-volume design accommodates the small aliquots pulled from time-point stability testing protocols.
- Trace-Level Quantitation - Conical micro-insert geometry channels limited sample volume to the needle tip for maximum analyte recovery.
- Pediatric Bioanalysis - Reduced dead volume enables accurate injection from the sub-milliliter specimen volumes typical in pediatric studies.
- 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.
- Metabolite Identification - Low-volume capability supports injection of concentrated extracts without dilution-related sensitivity losses.
