Conical Top Foam Cleanroom Swabs are constructed from compressed, 100 ppi (Z) open-cell polyurethane foam that is free from organic contaminants such as silicone, amides or phthalate esters. The foam is thermally bonded to the handle, thus, eliminating the use of contaminating adhesive or coatings. Laundered and packed under an ISO Class 5 Cleanroom, the foam exhibits low particulate and ionic content. It has excellent compatibility with most common solvents including acetone as well as excellent absorbency and solvent-holding capacity.
The foam head is compressed and possesses good firmness. The pointed, non-abrasive foam head is designed for cleaning small, slotted areas. The swab handle is made from polypropylene. The handle is compact and will not contribute to particulate or organic contamination. Designed for open-cell clean foam general purpose cleaning. Conical top foam cleanroom swabs are the ideal swabs to use in the cleanroom.
