White PTFE/Red Silicone 11x1mm Vial Septa, 100/Pk - CV1915
PTFE-lined chromatography septa from Tisch provide the chemical inertness and reseal integrity required for reliable autosampler injection across multiple needle punctures. 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.
Matching the right vial, cap, and septum configuration to your instrument and application ensures that sample containment never becomes a source of analytical uncertainty. PTFE chemical inertness at the sample contact surface keeps your chromatographic baseline clean, while the flexible backing delivers reliable reseal performance through repeated injections. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
