Thumbnail Filmstrip of Screw Top 9mm Glass .3mL HPLC Autosampler Clear Vials w/ Micro-Insert /Patch, 100/pk Images
Screw Top 9mm Glass .3mL HPLC Autosampler Clear Vials w/ Micro-Insert /Patch, 100/pk - CV1838
Micro-volume autosampler vials from Tisch feature integrated conical inserts engineered for maximum sample recovery from limited-volume specimens. Reduced internal volume concentrates the sample at the vial bottom, enabling reliable autosampler aspiration from specimens where analyte quantity limits total available volume. Consequently, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. 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.

- 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.
- 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.
- Precious Sample Recovery - Integrated insert eliminates the dead-volume losses that compromise quantitation of irreplaceable research specimens.
- Trace-Level Quantitation - Conical micro-insert geometry channels limited sample volume to the needle tip for maximum analyte recovery.
