Red PTFE/White Silicone 8x2mm Vial Septa, 100/Pk - CV1841
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. With this in mind, 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. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
