      Pre-Slit Red PTFE/White Silicone 11x1mm Vial Septa, 100/Pk - CV1883

      Engineered with a chemically inert PTFE contact layer, Tisch CV1883 vial septa prevent sample interaction with the seal material during storage and injection. Dimensional precision ensures uniform compression within the cap shell, preventing the uneven seal gaps that cause sample evaporation or atmospheric oxygen ingress. Standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.

      When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. PTFE chemical inertness at the sample contact surface keeps your chromatographic baseline clean, while the flexible backing delivers reliable reseal performance through repeated injections. 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.
      • 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.
      • Temperature-Cycled Storage - Operating range of -60 to 200 degrees Celsius accommodates refrigerated storage through elevated-temperature methods.
      • 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.
