250ul Micro-Insert, 29 x 5.7 mm for 9mm Vials, Mandrel Interior/Polymer Feet, 100Pk - CV2044
Combining a precision glass shell with a bonded micro-insert, Tisch CV2044 vials eliminate the alignment issues associated with loose insert configurations. Integrated design eliminates the air gaps and misalignment inherent in loose-insert configurations, reducing injection volume variability in quantitative trace-level methods. For this reason, 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. 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.
