CONSTIX® SF-11 swabs consist of a foam head formed over the end of a 6" cotton-tipped applicator with wood handle. The foam head is an 100ppi sealed closed-cell polyurethane foam.

• Birch hardwood handle makes it stiff enough for vigorous swabbing

The soft, polyurethane foam head provides good particle entrapment and removal. The absorbent foam enables solvents, such as isopropanol and ethanol, to be readily absorbed for applications involving solvent delivery or removal. No adhesives are used, and the wood handle is solvent resistant. The swab is low in particles and fibers and is well suited to applying solutions and adhesives. Though compatible with many common solvents, the SF-11 is not recommended for use with ketones such as acetone or MEK.
