The 44070 is a conical sealed foam swab designed for precision cleaning. It is constructed from reticulated 100 pores per inch medical-grade polyurethane foam, which provides excellent particle entrapment. The conical head is thermally bonded to a 3.2-inch polypropylene handle without using adhesives, tapering to a fine point for detailed work. Common applications include removing contamination from disk drives, micro-mechanical cleaning, and removing flux residue from printed circuit boards.
