Red PTFE/White Silicone 9x1mm Vial Septa, 100/Pk - CV1801
Engineered with a chemically inert PTFE contact layer, Tisch CV1801 vial septa prevent sample interaction with the seal material during storage and injection. Flexible backing layer provides the mechanical compliance needed for clean needle penetration and self-sealing recovery, maintaining a gas-tight closure through repeated punctures. As a result, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
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. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.

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