CONSTIX® SF-2 swabs consist of 100ppi sealed closed-cell foam head with a polypropylene handle. The swab head is thermally sealed and bonded to the handle without adhesives or binders.

• Large rectangular head ideal for swabbing larger areas and applying coatings

The polyurethane foam head provides good particle entrapment and removal. The large size of the foam head of the SF-2 swab provides better surface coverage for cleaning. The SF-2 swab is compatible with many solvents, such as isopropanol and ethanol, but is not recommended for use with ketones, such as acetone or MEK.
