The SV-3 is a sealed polyester swab that has been specifically designed for validation of surface cleaning protocols. The head is constructed of a double-layer knitted polyester fabric that has been processed to minimize background TOC contribution. The polyester head is constructed without adhesives or binders, which makes the swab compatible with most common solvents, such as alcohols and ketones.

• Large paddle swab head provides broader surface coverage for sampling and contamination retrieval in critical applications

The head is thermally bonded to a notched polypropylene handle to minimize handling and improve sample insertion into vials. The swab can be sterilized by most common methods, and the small put-up ensures accurate testing with little waste.
