Product Description
STX705W Sterile Cotton Swab is a sterile, individually wrapped, USP-grade spun cotton cleanroom swab designed for controlled-environment sampling and solvent-assisted cleaning where reach, absorbency, and point-of-use sterility matter. The cotton head is securely bonded to a long wood handle using an aqueous (water-based) adhesive, and the swab is gamma irradiated to 10-6 Sterility Assurance Level (SAL) to support aseptic workflows and documentation-heavy programs. Cotton is inherently fibrous (no swab is truly ‘lint-free’ in every process condition), so STX705W is typically selected when pickup/retention and compliant sampling workflows are the priority, with technique used to control low-linting outcomes.
