      Pre-Slit White PTFE/Red Silicone 11x1mm Vial Septa, 100/Pk - CV1918

      Rated for a temperature range of -60°C to 200°C, Tisch PTFE/Silicone chromatography septa maintain seal integrity across ambient and elevated-temperature analytical methods. PTFE sample-contact surface eliminates extractable contamination from the seal, preserving chromatographic baseline integrity across extended autosampler queue sequences. Consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.

      When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. 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.

      • 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.
      • 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.
      • Volatile Compound Analysis - Leak-resistant seal prevents analyte evaporation losses during extended autosampler queue wait times before injection.
