WFS742A Foam Cleanroom Swabs

The WFS742A is a foam swab with a total length of 69mm 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 short handle allows for better maneuverability. It is packaged in silicone-free and amide-free bags.
