Care and Use of Stopcocks with PTFE Plugs Kimble® PTFE stopcock plugs are made of the most chemically inert material in laboratory use today. Only a few chemicals have any effect on PTFE and these only at elevated temperatures and pressures. The material is extremely tough, durable and heat resistant, with practically zero moisture-absorption. It remains non-brittle even at sub-zero temperatures. • To clean new plugs, carefully disassemble, lift the plug free of the glass barrel, and rinse all parts of the plug and barrel in acetone. • After drying, reassemble and the stopcock is ready for use. (Do not use abrasive materials to clean either plug or barrel at any time.) • The PTFE washer must always be placed adjacent to the end of the glass barrel, to ensure minimal friction when turning. When properly tightened, the plug will be slightly more resistant to turning than a lubricated glass plug. • When not in use, store in a dust-free area with the plug loosened within the glass barrel. Although tough and unbreakable, PTFE is softer than glass and has a tendency to conform to the glass surface, including eventual expansion into the hollow parts of the barrel.
