Septa. A wide range of serrated and non-serrated septa, and sleeve stoppers are available for use as temporary closures for glassware joints, tubes, bottles, NMR tubes, ampules, and cannulation techniques in air-sensitive chemistry. To protect your valuable contents in the vessels or containers from the atmosphere, our range of septa provide
Rubber septa. Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis. PTFE is protective layer that once broken exposes rubber to chemical attack.
