Chemical-Resistant Tubing McMaster-Carr
WebMade of Polypropylene T504AQX screw cap incorporates a pierceable septum made of chemically resistant PTFE on the outside and silicone on the inside, both components being stable over a broad range of temperatures. The septum also acts as a silicone O-ring for better sample protection. It is…. Compare this item. WebChemical resistance PTFE PTFE is affected by some alkali metals (molten or in solution) and rare fluorinated compounds at high temperatures and/or pressures. Some organic and halogenated solvents are absorbed causing minor dimensional changes but these effects are physical and also reversible. morrocan theme backdrop
