Brand: Weston
SKU: 308293928

High-Density Foam Head for Effective Particle Removal
The Foam Cleanroom Swab uses high-density polyurethane foam that provides excellent wiping performance and effectively removes particles, residues, oils, and stubborn contaminants from sensitive surfaces.

Low Particle and Low Ionic Contamination
Manufactured with cleanroom-compatible materials, the swab features low particle generation, low non-volatile residue (NVR), and low ionic content, making it suitable for ISO Class 3 to ISO Class 8 cleanroom environments.

Superior Solvent Compatibility and Liquid Absorption
The foam head offers excellent absorbency and retention characteristics. The Foam Cleanroom Swab is compatible with IPA, ethanol, and other common cleaning solvents used in electronics and precision manufacturing industries.

Ultrasonically Bonded Construction for Enhanced Durability
The foam head and polypropylene handle are permanently bonded through an ultrasonic welding process, reducing the risk of head separation and ensuring reliable performance during critical cleaning operations.

Direct Manufacturing and Bulk Supply Capability
Weston manufactures Foam Cleanroom Swab products under strict quality control procedures with scalable production capacity, supporting OEM projects, customized specifications, and large-volume procurement requirements worldwide.
