Product Description
Restore a reliable, pierceable seal on threaded vials, flasks and caps with replacement PTFE/silicone septa. The PTFE face keeps the sample in contact with an inert surface, while the silicone backing reseals after needle punctures, so reagents can be added or withdrawn by syringe without exposing contents to air.
This listing is for Kimble catalog number 774161-0924: PTFE/Silicone Septum, Size 24, Case of 24. Septa are offered in sizes 8, 13, 15, 18, 20 and 24 to match common thread finishes and caps. Smaller sizes are packed 48 per case and larger sizes 24 per case. The size 20 septum is the matching replacement for several threaded microscale flasks and caps. Choose the size that corresponds to your cap or connector. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
