Contec CONSTIX Oval Sealed Foam Swab 6"
The Contec CONSTIX Oval Sealed Foam Swab (SF-3) consists of a 100 pore-per-inch sealed open-cell foam head. This head thermally seals and bonds to a polypropylene handle, without using adhesives or binders. The polyurethane foam head provides good particle entrapment and removal. The SF-3 swab is compatible with many solvents, such as isopropanol and ethanol, but we do not recommend using it with ketones, such as acetone or MEK.
