WFS712 Foam Cleanroom Swabs

The WFS712 is a square-headed cotton swab measuring 124mm in total length, made from high-quality 100ppi polyurethane foam and a 100% PP handle through a hot pressing process, eliminating the risk of adhesive contamination and reducing the generation of extraneous pollutants. It has very low non-volatile residues (NVR) and ion content. The open-cell polyurethane foam enhances particle capture ability, while the sturdy handle provides support and the flexible head offers maneuverability. The square head is ideal for cleaning large areas or intersecting surfaces and seams. Packaged in silicone-free and amide-free bags.
