      White PTFE/Red Silicone 13x1.5mm Vial Septa, 100/Pk - CV1936

      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. Pre-slit variants reduce needle coring by providing a defined penetration path, extending the effective puncture life and reducing particulate generation in the sample. Reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.

      Whether running routine QC sequences or method development campaigns, your confidence in sample integrity begins with the vial system on the autosampler tray. PTFE chemical inertness at the sample contact surface keeps your chromatographic baseline clean, while the flexible backing delivers reliable reseal performance through repeated injections. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.

      • Multiple Injection Sequences - Reseal-engineered construction maintains gas-tight closure integrity through repeated autosampler needle punctures.
      • 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.
      • 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.
      • Temperature-Cycled Storage - Operating range of -60 to 200 degrees Celsius accommodates refrigerated storage through elevated-temperature methods.
