WFS758 Foam Cleanroom Swabs

The WFS758 is a 70mm long polyurethane foam swab with a small flat head (paddle head) that is flexible and bendable, making it ideal for cleaning narrow areas and small cracks. The head is made from high-quality 100ppi (100 pores per inch) polyurethane foam, bonded through hot pressing to avoid adhesive contamination. These swabs are produced in a cleanroom environment, featuring extremely low ion and non-volatile residues (NVR). The highly automated manufacturing process ensures strict and consistent tolerances, compatible with various solutions and disinfectants, and packaged in silicone-free and amide-free bags.
