Foam Swab AV037
The SPI Big Mitts™ feature a large foam head thermally bonded to 5" (127 mm) polypropylene handles. Both the foam head and the handles are solvent resistant to most common laboratory solvents and are ideal for use with liquids of high solvency that tend to dissolve other plastic materials.
Obviously, neither the hear or the handles are PTFE, and there are of course, many organic liquids that will dissolve both polymers but for the most part, this combination of polyurethane and polypropylene has shown to be a highly reliable combination, over the long term.
