The SF-13 swab consists of 100 PPI open-cell foam tightly sealed around the tip of a glass-filled PP handle.

• Polyurethane foam head provides good particle entrapment and removal
• Foam is secured to the handle without the use of adhesives or binders
• Very low in particles and fibers

The foam head conforms tightly to the pointed shape of the swab handle to provide a very fine tip that enables access to small areas and crevices. The absorbent foam enables solvents, such as isopropanol and ethanol, to be readily sorbed for applications involving solvent delivery or removal.

Though compatible with many common solvents, the SF-13 is not recommended for use with ketones such as acetone or MEK.
