Sealed knitted polyester swabs for surface cleaning validation.

• Heads are constructed of a double-layer knitted polyester fabric that has been processed to minimise background TOC contribution
• Heads are thermally bonded to a notched PP handle to minimise handling and improve sample insertion into vials
• Polyester heads are constructed without adhesives or binders
• Compatible with most common solvents, such as alcohols and ketones
• Swabs can be sterilised by most common methods
• Small put-up ensures accurate testing with little waste

SV-2: The round head and flexible handle of SV-2 allows access to recessed surfaces for easier contamination retrieval or sampling.
