Red thermoset plastic caps with PTFE Liners are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. PTFE liners resist attack from virtually all chemicals at room temperature and provides odor and impact resilience for a tight seal with a low moisture transmission rate. Some uses for these PTFE lined caps include analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents.

Application:

Amber vials fitted with PTFE-lined screw caps may be used to store soil sample extracts at -20 °C under nitrogen, in an experimental study demonstrating usage of lignin-degrading fungi for bioaugmentation, as a viable solid-phase treatment option, for the remediation of pentachlorophenol (PCP) contaminated-soils.
