WFS742B Foam Cleanroom Swabs

The WFS742B is a cleanroom swab with a total length of 150mm and a cylindrical head, 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 features very low non-volatile residues (NVR) and ion content. The open-cell polyurethane foam enhances particle capture ability, while the small head is easy to use for cleaning narrow and tight spaces, and the long handle allows for cleaning hard-to-reach areas. It is packaged in silicone-free and amide-free bags.
