SW-122C Double Head Dust-Free Foam Swab

Product Overview

The SW-122C is a double-head dust-free swab with flat polyester foam tips at both ends of a short polypropylene handle, designed for sequential precision cleaning tasks where a single-ended swab requires a replacement mid-workflow to avoid recontaminating a surface with residue absorbed on the first pass. The double-head configuration provides a clean tip on demand — the operator uses the first end for solvent application or initial residue uptake, then flips to the second end for the finishing wipe, maintaining a fresh contact surface for the final cleaning step without opening a second swab package.

Each foam head measures 13mm in length, 5mm in width, and 1mm in thickness. The 1mm thickness is the flattest head profile across this entire product line — thinner than any other swab in the sponge or polyester series — producing a near-planar contact surface that suits precision flat-surface cleaning tasks: wiping optical lens faces, cleaning display screen active areas, removing dust from flat sensor surfaces, and applying reagents uniformly across flat substrate zones. At 1mm, the head does not extend significantly beyond the handle edge, which is a functional advantage when cleaning in shallow recesses or between tightly-spaced component rows where a thicker foam head would contact adjacent structures.

Anti-Shedding Treatment & Dust Capture Performance

The polyester foam head material has undergone anti-shedding surface treatment that prevents fiber release during cleaning contact, eliminating the secondary contamination risk that untreated foam presents on high-value optical surfaces and electronic components. The dust-free construction gives the SW-122C its primary functional advantage over standard foam swabs in precision cleaning applications: the treated surface actively adsorbs and locks fine dust particles during the wiping pass, rather than merely displacing them across the substrate. This particle-capture behavior is particularly relevant for display screen maintenance, optical flat glass cleaning, and electronic component surface preparation where residual particles after cleaning cause rejection at downstream inspection stages.

The polypropylene handle measures 80.5mm in total length with 4mm width and thickness — a square-section handle profile that provides stable four-sided grip and prevents the swab from rotating in the operator's fingers during the controlled lateral strokes required for flat-surface cleaning. The double-head design makes it cost-efficient for two-stage cleaning workflows. Package contains 100 pieces.

Industry Applications & Use Scenarios

The SW-122C is used in electronic component cleaning, optical instrument maintenance, precision machinery servicing, display panel manufacturing, and laboratory instrument cleaning tasks where the flat foam geometry and dual-end configuration deliver cleaning performance that single-ended or thicker-head alternatives cannot replicate. Specific use scenarios include cleaning optical lens flat faces before coating or inspection, removing dust from LCD and OLED display surfaces, two-stage cleaning of electronic component contact pads (application pass followed by dry wipe), cleaning precision machinery bearing races and contact surfaces, and laboratory cleaning tasks requiring alternating wet-and-dry swabbing steps on the same component. The ultra-thin 1mm head is the key selection driver for tasks where spatial clearance between the cleaning target and adjacent structures is less than 2mm.
