The CF50 is a general-purpose cleaning swab designed for a variety of applications. It is constructed with a 6-1/8 inch wood handle and a unique foam-over-cotton head, which is thermally bonded without adhesives. This design leverages medical-grade foam with an open-cell structure for excellent particle entrapment and high solvent capacity, while its fiberless nature prevents particle generation during use. These swabs are ideal for tasks such as removing flux residue from PCBs, cleaning excess adhesives, micro-mechanical cleaning, and general maintenance of office equipment.
