Screw Top 9mm Glass 0.3mL HPLC Autosampler Clear Vials w/ Integrated Micro-Insert, 100/Pk - CV1837
Combining a precision glass shell with a bonded micro-insert, Tisch CV1837 vials eliminate the alignment issues associated with loose insert configurations. Base-bonded insert construction prevents liner displacement during autosampler needle descent, maintaining consistent needle-to-sample distance across the full injection sequence. Standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
From tray loading through the final injection in an overnight sequence, your sample containment system should perform without introducing the variables your method is designed to control. Integrated micro-insert geometry lets you recover maximum analyte from minimum sample volume, eliminating the dead-volume losses that compromise trace-level quantitation. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.

- Trace-Level Quantitation - Conical micro-insert geometry channels limited sample volume to the needle tip for maximum analyte recovery.
- 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.
- Stability Study Samples - Micro-volume design accommodates the small aliquots pulled from time-point stability testing protocols.
- Pediatric Bioanalysis - Reduced dead volume enables accurate injection from the sub-milliliter specimen volumes typical in pediatric studies.
- Precious Sample Recovery - Integrated insert eliminates the dead-volume losses that compromise quantitation of irreplaceable research specimens.
