Texwipe TX759B Micro Absorbond Polyester Cleanroom Swab (Hydroentangled Nonwoven, Thermal Bond)

Texwipe TX759B is a micro-format, dry, low-linting polyester cleanroom swab engineered for precision cleaning and sampling inside tight geometries — grooves, tracks, slots, and other confined features — as well as sensitive surfaces such as optical assemblies. The swab head is made from 100% polyester (hydro-entangled) non-woven Absorbond material in a double-layer construction for enhanced absorbency and contaminant pickup, then thermally bonded (no adhesive) to a virgin polypropylene handle to help reduce residue risk in solvent-driven workflows. With a compact handle and flexible internal head paddle, TX759B is designed to improve operator control during micro-cleaning steps where geometry repeatability matters as much as chemistry.

Texwipe (an ITW company) is widely specified in contamination-control programs because it treats the swab as an engineered tool, not a commodity. For Absorbond® polyester nonwoven swabs like TX759B, that engineering focus shows up in hydroentangled head construction (soft contact on sensitive surfaces with a 3D fiber network for pickup), tight dimensional tolerances for repeatable access into small features, and thermal bonding that removes adhesive as a contamination variable.

Texwipe also emphasizes lot coding, cleanroom processing, and packaging controls (including silicone-free and amide-free bagging for this line) to reduce unknowns during troubleshooting and qualification. SOSCleanroom (SOS) supports that discipline with an established working relationship focused on continuity of supply, documentation handoff, and practical application support—so customers can standardize micro-cleaning and sampling steps with predictable performance and procurement reliability.

• 100% polyester (hydro-entangled) non-woven Absorbond head material
• Double-layer nonwoven polyester head for enhanced absorbency and pickup
• Thermal bond construction (no adhesive) to help reduce residue risk in solvent workflows
• Cleanroom processed to provide ultra-low levels of particles, NVRs (nonvolatile residues), and ions
• Excellent chemical resistance for compatibility with a variety of solutions (verify with your specific chemistry and SOP)
• 100% virgin polypropylene handle for controlled handling and chemical resistance
• Autoclave safe in dry heat and steam
• Lot coded for traceability and quality control
• Packaged in a silicone-free and amide-free bag
• Light-green handle color and “TEXWIPE” embossing are commonly used as practical, line-side identification cues alongside approved sourcing and lot controls

• Micro-access geometry: A 3.2 mm (0.126") wide head supports cleaning and sampling inside narrow slots, grooves, tracks, and recessed features where wipes cannot maintain contact.
• Sensitive-surface performance: Hydroentangled polyester is commonly selected for gentle, controlled contact on optics and other scratch-sensitive surfaces (technique and pressure still determine outcomes).
• Lower residue risk by design: Thermal bonding removes adhesive as a potential source of unknown extractables that can show up as streaks, haze, or analytical interference.
• Improved handling control: Compact 70.0 mm overall length and a flexible head paddle support better tactile feedback during precision work.
• Audit-friendly traceability: Lot coding and controlled packaging help support investigations, qualification, and change-control discipline.

• Precision cleaning of grooves, tracks, slots, rails, channels, and other small spaces
• Optical cleaning tasks on sensitive surfaces such as optical assemblies and precision components
• Solvent use (such as IPA) for controlled film lifting, residue removal, and spot cleaning
• Targeted cleaning inside cavities, interfaces, and tight mechanical joints where larger swabs cannot fit
• Sampling workflows where capture and release into a diluent are part of the method (define area, strokes, wetting method, and extraction protocol)

• Control wetness: For solvent work, aim for damp—not dripping—to prevent pooling and re-deposition inside features.
• Single-pass discipline: Use one-direction strokes; rotate the tip early and often. Micro tips have limited usable surface area before smearing risk increases.
• No re-dipping: Avoid re-dipping into solvent reservoirs (a common cross-contamination mechanism). Use single-use aliquots or controlled dispense.
• Pressure control: Use film-breaking pressure, not surface-loading pressure—especially on optics, coatings, and polished metals.
• Define the boundary: Work cleanest-to-dirtiest and avoid touching the “dirty wall” of a slot, then dragging contamination across adjacent critical areas.

• Micro access vs. reach (TX759B vs. TX762): Choose TX759B for compact, micro-feature access and maximum control; step up to a long-handle Absorbond swab like TX762 when you need reach into deeper channels while keeping gloves away from the work zone.
• Nonwoven micro tip vs. knit polyester paddle (TX759B vs. knit swabs): TX759B’s hydroentangled nonwoven micro head is optimized for tight features and sensitive-surface contact; a larger knit polyester paddle swab may be preferred when you want a broader, flatter contact patch for larger wipe points.
• Solvent reality check: Swab compatibility and performance are process-dependent. Always qualify dwell time, pressure, and stroke method with your exact solvent, surface finish, and acceptance criteria.
