At a glance (what makes TX759B different)
- Micro head geometry: 3.2 mm head width supports narrow features and controlled contact.
- Hydroentangled polyester nonwoven (double layer): soft on sensitive surfaces, strong pickup in a 3D fiber network.
- Thermal bond (no adhesive): reduces a common residue variable at the head/handle interface in solvent-wet work.
Practical solutions in a critical environment
Micro-cleaning failures rarely announce themselves as “hard-to-reach.” They show up as a faint film line at the end of a slot, a haze on a small optical land, or an intermittent residue signature that only appears after solvent evaporates. In that moment, the swab becomes either a controlled tool or a variable: twist, over-wet, rework a pass, and the process drifts into redeposition and streaking.
TX759B is designed to keep micro work repeatable. It uses a compact, micro-format Absorbond® head made from 100% polyester hydroentangled nonwoven material in a double-layer construction for absorbency and contaminant capture. The head is thermally bonded to a virgin polypropylene handle (no adhesive), helping reduce a hidden contamination and residue contributor in solvent-driven workflows.
Low-linting outcomes depend on technique and surface condition. No swab is truly lint-free; edge sharpness, surface roughness, solvent load, contact pressure, and stroke discipline govern what you see on the part.
What is this swab used for
Texwipe TX759B is used for precision cleaning and controlled solvent application/removal in grooves, tracks, slots, and other small spaces where a broader swab face can flood a feature or leave a drying ring. It is also used on sensitive surfaces (including optics, glass, and mirrored surfaces) when the goal is gentle contact plus controlled pickup.
Common solvent use includes IPA (validate compatibility with your surface, coating, inks, and assembly materials). The manufacturer also positions Absorbond® nonwoven polyester as broadly chemically resistant for compatibility with a variety of solutions, but the correct chemistry is always process-specific: match solvent to the residue mechanism instead of increasing pressure or stroke count.
Why should customers consider this swab
- Micro head geometry (3.2 mm width) supports controlled access and reduces flooding risk in narrow features.
- Hydroentangled polyester nonwoven, double-layer head improves absorbency and contaminant capture while remaining soft on sensitive surfaces.
- Thermal bond construction eliminates adhesive at the bond line, reducing a residue variable in solvent-wet work.
- Published ion extractables and NVR data help establish realistic background expectations for residue-sensitive cleaning and investigations.
- Silicone-free and amide-free bag packaging supports processes sensitive to silicone transfer and slip-additive artifacts.
- Lot-coded packaging supports investigations; light-green handle and “TEXWIPE” embossing are practical line-level identification cues.
- High-count packaging (500/bag with inner packs) supports point-of-use control without repeatedly opening the full outer bag.
Materials and construction
Head: 100% polyester hydroentangled nonwoven (Absorbond®), double layer
Head bond: thermal bond (no adhesive at the bond)
Handle: 100% virgin polypropylene; compact handle; handle color: light green
Practical implication: micro swabbing is easy to “over-control.” Avoid twisting in the feature. Keep the head square to the geometry, use single-direction passes, and treat burrs and sharp edges as a process risk. If the part has edge burrs, reduce pressure near the exit and do not drag the head across sharp corners.
Specifications in context
TX759B is a 2.756-inch overall swab with a 10.0 mm head length and a 1.5 mm head thickness. Use the micro head width to standardize “feature coverage” (stroke count and overlap) so the process does not drift into scrubbing. Head thickness and length help manage solvent load: thicker heads can hold more solvent, which increases the importance of “damp” technique to prevent pooling and drying rings at the end of a slot or track. Handle dimensions matter because micro work is wrist-driven; if the handle is too small for the glove and grip style, the operator will compensate with twist and pressure—exactly what causes redeposition lines.

Cleanliness metrics
The values below represent published typical analyses and are not per-unit specifications. Use them for risk assessment, method development, and troubleshooting. If you run film-sensitive work (optics, polished metals, coated parts) or validate cleaning (TOC, HPLC/UV-Vis, ion chromatography), qualify the swab with your solvent, your surfaces, your stroke count, and your inspection method so the swab does not become the dominant background signal.

Operator takeaway: micro heads flood quickly. Keep the head damp, rotate faces early, and stop when drag increases. If you see a drying ring at the edge of a slot, reduce solvent load and shorten the finish stroke so the end-of-stroke does not pool.
Packaging, sterility and traceability
- Packaging (TX759B): 500 swabs/bag (5 inner bags of 100 swabs); 5 bags/case; 2,500 swabs/case
- Bag packaging controls: silicone-free and amide-free bag packaging
- Sterility: non-sterile (do not attempt to “make a non-sterile swab sterile” at the bench; if sterility is required, select a sterile swab supplied in sterile packaging with defined expiration controls)
- Shelf life (series statement): 5 years from date of manufacture
- Traceability cues: lot-coded packaging supports investigations; light-green handle and “TEXWIPE” embossing support practical line segregation
- Country of origin (manufacturer statement): Made in The Philippines
Best-practice use
Treat TX759B as a micro tool, not a miniature wipe. The goal is controlled contact and controlled solvent delivery—not scrubbing. Define stroke count, overlap, and discard triggers so operators do not “chase” a film line by reworking it with a loaded face.
Operator-level swabbing technique module
- “Damp” solvent technique: Wet the head, then reduce to damp (not dripping). A practical check is one controlled touch to a cleanroom wipe to remove excess. You want a light, even wet track, not a bead. Over-wetting increases pooling and tide marks.
- Stroke-count logic for slots/tracks: Use single-direction strokes with overlap. Make 1–3 passes per face, then rotate to a clean face. Discard when drag increases, the face shows visible loading, or the work starts to streak.
- Geometry control: Keep the head square to the feature. Avoid twisting at the wrist, which pushes dissolved residue into a line at the end of the stroke. Control the exit angle so you do not wipe a dissolved line onto an adjoining “clean” surface.
- Pressure guidance: Use only enough pressure to maintain contact. Excess pressure can squeegee mobilized residue into a line, abrade soft coatings, and accelerate fiber/particle release when a burr is present.
- Solvent compatibility framing: IPA is common. Validate compatibility with the surface, coating, ink, and adhesive systems. If residue does not dissolve, change chemistry or dwell strategy rather than increasing pressure or stroke count.
- Handling discipline: Stage only what you need. Use inner bags (100-count) as point-of-use packs to reduce repeated full-bag openings. Do not re-dip a used swab into a shared solvent reservoir; decant to a small working vessel and replace it frequently.
Qualification checklist (fast, practical, audit-friendly)
- Document solvent grade, decant method, and wetness control check.
- Define stroke count per feature and define discard triggers (drag, visible loading, streaking).
- Capture lot code, inner-bag ID, and inspection results (visual and/or analytical).
- If validating cleaning (TOC/HPLC/IC), match extraction solvent to your real process—not a “convenient” proxy.
Common failure modes
- Over-wetting the head and flooding a slot or seam, leading to pooling and visible drying rings.
- Reworking the same area with a loaded face, causing streaks and redeposition.
- Twisting at the wrist in a track/slot, pushing dissolved residue into a line at the end-of-stroke.
- Using excessive pressure on a burr or sharp edge, causing snagging and localized release.
- Cross-contaminating solvent by re-dipping or using a shared reservoir without decant-and-refresh discipline.
Closest competitors
The closest alternatives are micro-format polyester swabs intended for sensitive surfaces and tight features, where selection hinges on head construction, bond method, published cleanliness data, and packaging/traceability controls. Compare wetting behavior (flooding risk), snag resistance near edges, and whether the supplier provides extractables/NVR data and lot coding that supports investigations.
- Contec micro polyester swab classes: Often positioned for controlled surface contact. Compare construction method, durability under solvent-wet passes, and documentation depth for ions/NVR and lot traceability.
- Berkshire micro polyester swab classes: Similar intent for sensitive surfaces. Evaluate how the head behaves under your solvent and inspection method and whether published cleanliness support is sufficient for your program.
- Puritan micro polyester swab formats: Comparable form factors may be available. Confirm thermal-bond versus adhesive interfaces, published cleanliness information, and lot coding that supports repeatable qualification.
Critical environment fit for this swab
TX759B fits work where tight features and sensitive surfaces intersect: microelectronics, optics, semiconductor tool cleaning, device assembly, and laboratory operations where controlled solvent delivery and consistent geometry matter. It is a strong choice when you want a defined micro contact patch to support consistent, auditable technique rather than operator-dependent scrubbing.
SOSCleanroom’s relationship with ITW Texwipe supports continuity of supply and documentation discipline, which reduces the risk of unplanned substitutions that change wetting behavior and background extractables. That matters in ISO-aligned cleanroom programs (ISO 14644-1) and in regulated environments where documentation expectations often track FDA quality systems and standards-driven methods associated with ASTM and IEST.
Operational support matters, too. Fast shipping and responsive customer service help keep validated work instructions intact by preventing “make-do” material swaps when production schedules tighten.
