The SP-1 is a sealed polyester swab consisting of 100% knitted polyester fabric thermally bonded to a polypropylene handle.

• Sealed polyester head provides the lowest contamination risk of any other type of swabs
• Polypropylene handle provides excellent resistance to most common solvents, acids, and bases

The SP-1 contains no adhesives or binders. The swab head is made from cleanroom laundered polyester fabric. These swabs are the best option to use with harsh solvents such as acetone, trichloroethane, and nitric and sulfuric acids. The SP-1 swabs are durable, absorbent, and extremely low in particulate and residue levels.
