Product Description
VialMAX™ 15-425 Screw Cap for 4mL and 8mL vials with Pre-assembled Red PTFE/White Silicone Septa, Closed Top, case of 1,000
A loose or low-purity septum is how solvent evaporates out and air gets in, right when you need a clean, repeatable injection. VialMAX closed-top screw caps come with a high-purity red PTFE/white silicone septum preassembled, so you get a secure seal and reliable resealability through repeated injections.
And yes, we ship these to your door with NO hidden fees. No handling fees, no "why does this cost more than the website said" moments. Just the product, free ground shipping, and a clean invoice!
