The SFW-1 is a foam swab consisting of a 100 pore-per-inch open cell foam tightly wrapped around the tip of a birchwood toothpick. The foam is secured to the handle without the use of adhesives or binders. The open-cell foam provides excellent particle entrapment and retention, while the tightly wrapped head is resistant to abrasion. The SFW-1 is sorbent to most common solvents, but is not recommended for use with ketones.
