Low profile for greater stability, wide mouth for ease of sampling, these Clear Compound Vials are excellent for small quantities of compounds. The Lab-Pak carton includes a shrink wrapped tray of 144 Vials and a bag of 144 Green Thermoset F217 PTFE lined caps (not assembled).
Green thermoset (phenolic) are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. The color green easily identifies the PTFE liner system. Foam backed PTFE liners resist attack from virtually all chemicals at room temperature and provides resilience for a tight seal with a low moisture transmission rate. F217 has a low density foam core between two solid layers of LDPE. Uses include analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents.
