Red PTFE/White Silicone 11x1mm Vial Septa, 100/Pk - CV1916
Dual-layer construction in Tisch chromatography septa combines PTFE chemical resistance on the sample-contact side with flexible backing for reliable needle penetration and resealing. PTFE sample-contact surface eliminates extractable contamination from the seal, preserving chromatographic baseline integrity across extended autosampler queue sequences. Standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. Precise dimensional cutting ensures uniform compression in the cap shell, giving you the consistent seal that prevents evaporation losses across extended autosampler queues. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.

- Light-Sensitive Samples - Pre-slit configurations reduce coring and particulate generation during needle penetration of amber vial closures.
- HPLC Mobile Phase Contact - PTFE sample-contact layer provides chemical inertness across acidic, basic, and organic mobile phase conditions.
- Volatile Compound Analysis - Leak-resistant seal prevents analyte evaporation losses during extended autosampler queue wait times before injection.
- Low-Extractable Requirements - Inert PTFE contact surface minimizes septum-derived contaminant peaks that interfere with trace-level baselines.
- Multiple Injection Sequences - Reseal-engineered construction maintains gas-tight closure integrity through repeated autosampler needle punctures.
- Temperature-Cycled Storage - Operating range of -60 to 200 degrees Celsius accommodates refrigerated storage through elevated-temperature methods.
