Screw Top 8mm White Plastic Vial Cap w/ Red PTFE/White Silicone/Red PTFE Septa, 100/Pk - CV1858
Pre-assembled cap and septum combinations from Tisch streamline sample preparation by delivering a matched closure system ready for immediate use. Factory assembly under controlled conditions ensures each septum seats with uniform compression, delivering predictable reseal characteristics from the first through the final injection. On this basis, stringent manufacturing tolerances across vials, caps, and septa ensure that every component in the sample containment chain performs to the specifications modern analytical methods demand.
Reliable injection-to-injection reproducibility in your chromatographic workflow starts with consumables engineered to maintain dimensional and chemical consistency across every lot. Pre-assembled construction saves you the bench time of individual septum placement while delivering the lot-to-lot consistency your validated methods require. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
