Qorpak Natural Nylon/PE Modern Round, Green Thermoset F217 Teflon® Lined Cap
Natural Nylon/PE Modern Round, Green Thermoset F217 Teflon Lined Cap
The attached green thermoset (phenolic) caps are known for having the widest range of chemical compatibility and temperature tolerance for plastic closures. The PTFE liner system is identified by the green color. Foam backed PTFE liners resist attack from virtually all chemicals at room temperature and provides a tight seal with a low moisture transmission rate. F217 has a low density foam core between two solid layers of LDPE. Used to store strong acid solvents, analytical lab samples, environmental samples, pharmaceuticals, high purity samples, and diagnostic reagents.
