Pre-Slit Blue PTFE/White Silicone 9x1mm Vial Septa, 100/Pk - CV1805
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. Altogether, consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. Precise dimensional cutting ensures uniform compression in the cap shell, giving you the consistent seal that prevents evaporation losses across extended autosampler queues. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.
