The SW-822C is a pointed foam cleanroom swab with a closed-cell polyurethane foam head, built for precision cleaning tasks that require access to narrow cavities, recessed surfaces, and component internals where flat or rectangular swab heads cannot make effective contact. The closed-cell foam construction provides higher resistance to tearing and compression deformation compared to open-cell alternatives, which is relevant in applications involving repeated contact with hard substrate edges.
The swab head measures 11.5mm in length, 3.2mm in width, and 3.2mm in thickness, tapering to a pointed tip geometry that concentrates cleaning contact on small-area targets. This profile is suited for cleaning the interiors of connector housings, the tip areas of precision nozzles, pin gaps in electronic assemblies, and micro-channel cleaning in medical device components.
The foam material produces low particle generation during use and exhibits low NVR, which supports its application in ISO Class 4–7 cleanroom environments. Solvent compatibility includes IPA and other standard cleaning agents used in semiconductor assembly and optical manufacturing. The closed-cell structure limits over-absorption, providing more consistent liquid delivery than open-cell foam in application tasks.
The polypropylene handle is 73mm in total length with 2.6mm width and thickness, sized for single-finger operation in confined working spaces. The compact handle format is practical for inspection station workflows and rework operations in electronics manufacturing.
Application industries include semiconductor manufacturing, precision electronics assembly, pharmaceutical cleanroom operations, optical cleaning, and laboratory cleaning. Specific use scenarios include printer head cleaning, sensor tip cleaning, lens interior cleaning, and detailed maintenance of precision instruments. Packages are available in 100-piece small packs and 500-piece large packs.
