Red PTFE/White Silicone 11x1mm Vial Septa, 100/Pk - CV1880
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. Pre-slit variants reduce needle coring by providing a defined penetration path, extending the effective puncture life and reducing particulate generation in the sample. Working in concert, 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. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
