Aijiren provides one of the widest selections of Caps, Closures, and Lids available. Select from a wide variety of metal and phenolic, and polypropylene plastic bottle caps, vial lids, and other closures with an array of lining systems to fit your application and container. We also feature dispensing caps, hole caps, septa, tube caps, and vial caps. PP cap is made in one molded piece of inert, chemically resistant polyethylene. The starburst slits allow for easy needle penetration. Developed for high-sensitivity applications, especially in the LCMS Market, the purity of this cap for extractables is well below the picogram range. This high-grade polyethylene does not have the contamination issues PTFE/Silicone septa show at low levels of detection, while also sealing exceptionally well. The PP cap will puncture with far less force than needed to puncture a PTFE/Silicone septa, thus minimizing instrument wear and tear as well as downtime. The septa are not resealable and are intended for single use.
