Natural PTFE/Natural Silicone 22x1.5mm Vial Septa, 100/Pk - CV1984
Precision-cut to exact dimensional specifications, Tisch CV1984 septa deliver consistent compression and seal performance across crimp, snap, and screw-thread closure systems. Dimensional precision ensures uniform compression within the cap shell, preventing the uneven seal gaps that cause sample evaporation or atmospheric oxygen ingress. Stringent manufacturing tolerances across vials, caps, and septa ensure that every component in the sample containment chain performs to the specifications modern analytical methods demand.
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. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.

- 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.
- HPLC Mobile Phase Contact - PTFE sample-contact layer provides chemical inertness across acidic, basic, and organic mobile phase conditions.
- Temperature-Cycled Storage - Operating range of -60 to 200 degrees Celsius accommodates refrigerated storage through elevated-temperature methods.
- Light-Sensitive Samples - Pre-slit configurations reduce coring and particulate generation during needle penetration of amber vial closures.
