WFS707 Foam Cleanroom Swabs

The WFS707 is a square-headed swab with a total length of 129mm, made from high-quality 100ppi polyurethane foam and a 100% PP handle using a heat-sealed process. There is no risk of adhesive contamination, minimizing the generation of unwanted contaminants. The non-volatile residue (NVR) and ionic content are extremely low. The open-cell polyurethane foam offers superior particle capture capability, while the sturdy handle provides support and the flexible paddle head ensures flexibility. The square head is ideal for cleaning large surfaces or intersecting areas and seams. It is packaged in silicone-free and amide-free bags.
