Red PTFE/White Silicone 11x1mm Vial Septa, 100/Pk - CV1917
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. By design, standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
Your chromatographic results depend on the integrity of every seal, every vial surface, and every needle penetration — precision that starts with the consumables you select. PTFE chemical inertness at the sample contact surface keeps your chromatographic baseline clean, while the flexible backing delivers reliable reseal performance through repeated injections. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.

- Light-Sensitive Samples - Pre-slit configurations reduce coring and particulate generation during needle penetration of amber vial closures.
- Low-Extractable Requirements - Inert PTFE contact surface minimizes septum-derived contaminant peaks that interfere with trace-level baselines.
- Volatile Compound Analysis - Leak-resistant seal prevents analyte evaporation losses during extended autosampler queue wait times before injection.
- HPLC Mobile Phase Contact - PTFE sample-contact layer provides chemical inertness across acidic, basic, and organic mobile phase conditions.
- 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.
