Tight geometry is where “good intentions” create contamination. A short swab forces awkward wrist angles, unstable contact, and glove proximity that turns the operator into the closest shedding surface. Then the chemistry gets blamed: too much solvent floods a track and leaves a drying ring, too little solvent drags and smears, and a reused swab face redeposits a residue line that only shows up under inspection lighting.

TX761 is designed for that operator reality. The long handle helps keep gloves and sleeves out of the work zone while maintaining stable tip control in recessed features. The Alpha® double-layer polyester knit head provides predictable sorbency for “damp” solvent technique (commonly IPA, but validate compatibility with your materials), and the head is thermally bonded to the handle to eliminate adhesive at the head/handle interface.

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.

Texwipe TX761 is a non-sterile Alpha® series cleanroom swab used for precision spot cleaning and controlled application or removal of fluids in recessed or hard-to-access features. It is commonly selected for grooves, tracks, slots, channels, and tight corners where a shorter swab encourages poor angles and incidental-contact contamination.

Practical use includes controlled solvent application/removal (to avoid flooding and film/tide marks), lifting localized residue lines before they migrate, and applying/removing lubricants, adhesives, and process solutions where background control and traceability matter.

• Long handle improves reach and stability in recessed geometry while keeping gloves and sleeves away from the surface.
• Alpha® double-layer polyester knit supports predictable pickup/release for “damp” technique rather than flooding.
• Thermal bond construction eliminates adhesive at the bond line, reducing a common residue variable in solvent-wet work.
• Published typical ion extractables and NVR data support method development, baseline setting, and troubleshooting.
• Silicone-free and amide-free bag packaging reduces packaging-related unknowns in residue-sensitive workflows.
• Trademarked light-green handle with “TEXWIPE” embossed on the handle is a practical line-level segregation and traceability cue (a process identifier, not a legal claim).

Head: knitted Alpha® polyester (double layer)

Head bond: thermal bond (no adhesive at the bond)

Handle: 100% virgin polypropylene; long handle; handle color: light green

Practical implication: use the knit head like a controlled, flat contact face. Avoid dragging across burrs or sharp edges inside grooves and slots; reduce pressure near edges, keep the swab aligned to the feature, and do not “power through” snag points that can create localized fiber or particle release.

TX761’s geometry is engineered around access and control, not broad coverage. The 6.39-inch overall length and 5.728-inch handle length are the “process feature” here: they help maintain a stable approach angle in deep or recessed features and keep glove proximity from becoming the dominant contamination source. The 0.268-inch head width and 0.661-inch head length support repeatable stroke count and overlap inside tracks and channels, while the knit thickness helps hold enough solvent to stay damp without turning the feature into a reservoir.

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

Operator takeaway: the long handle makes it easy to “lever” the swab and overload pressure at the tip. Use just enough pressure to maintain contact, keep the head damp, rotate faces early, and stop when drag increases. If a groove shows a drying ring, reduce solvent load and shorten the finish stroke so the end-of-stroke does not pool.

• Packaging (TX761): 100 swabs/bag (inner bag: 100 swabs); 10 bags/case; 1,000 swabs/case
• Bag packaging controls: silicone-free and amide-free bag packaging
• Sterility: non-sterile (if sterility is required, select STX761 and confirm method impact; do not assume a direct one-for-one substitute without qualification)
• Autoclave note (process-specific): the Alpha® series is described as autoclave safe in dry heat and steam; validate how autoclaving impacts your cleanliness baseline and handling discipline
• Shelf life (series statement): non-sterile 5 years from date of manufacture; sterile 3 years from date of manufacture
• Traceability cues: lot coded packaging; trademarked light-green handle color with “TEXWIPE” embossed on the handle supports practical line segregation and investigation traceability
• Country-of-origin (manufacturer statement): Non-sterile – Made in The Philippines; Sterile – Made in The Philippines, irradiated in the U.S.

Treat TX761 like a precision tool, not a “reach stick.” The goal is controlled contact and controlled solvent delivery inside the feature. Define stroke direction, stroke count, overlap, and discard triggers so operators do not drift into scrubbing or reworking a residue line with a loaded face.

• “Damp” solvent technique: Apply solvent to the head, then reduce to damp, not dripping. A practical check is one controlled touch to a blot surface to remove excess. You want a light, even wet track, not a bead. Over-wetting floods channels and creates tide marks as solvent evaporates.
• Track/groove stroke control: Use single-direction strokes aligned to the feature. Avoid sawing motions. For rails and grooves, use 2–4 defined passes, then stop and inspect. Rotate to a fresh face early; do not “chase” a line with a loaded tip.
• Angle discipline: Keep the head square to the contact surface. The long handle can tempt wrist twist; twist increases edge digging and leaves a pressure line at the end of the stroke.
• Pressure guidance: Use only enough pressure to maintain contact. Excess pressure can squeegee dissolved residue into a line or abrade softer surfaces inside the feature.
• No re-dip rule: Do not re-dip a used swab into a shared solvent reservoir. Decant to a small working vessel and refresh it frequently to prevent cross-contamination.
• Documentation cues for investigations: Capture lot code, solvent grade, wetness-control method, stroke count, extraction timing (if sampling), and inspection outcome. That data is what separates a real drift event from technique variation.

• Over-wetting a groove or channel, leading to pooling, drying rings, and solvent-driven residue redistribution.
• Reworking the same feature with a loaded face, causing redeposition and streaks.
• Wrist twist that turns a flat contact into edge digging, creating a pressure line and uneven cleaning.
• Snagging on burrs or sharp edges and pulling fibers/particles into the feature.
• Cross-contaminating solvent through re-dipping or shared reservoirs without decant-and-refresh discipline.

Comparable alternatives are long-handle polyester swabs designed for tight-geometry access. Selection typically hinges on knit behavior under your solvent, bond method (thermal vs. adhesive), published contamination data, and packaging and traceability controls that support investigations.

• Contec CONSTIX® sealed polyester swab class (SP series): Often positioned for controlled surface contact with sealed construction approaches. Compare durability in grooves, bond mechanism, and documentation depth (typical extractables data, lot traceability, packaging discipline).
• Berkshire Lab-Tips® polyester knit swab class: Knit-based options often evaluated for critical cleaning and residue-sensitive workflows. Qualify wetting behavior and baseline background in your method.
• Puritan long-handle polyester swab formats: Comparable access geometries may be available. Confirm bond method, packaging controls, and availability of extractables information required by your program.

TX761 is a strong fit for ISO-aligned cleanroom programs where tight-geometry cleaning needs to be repeatable and auditable: process tools, fixtures, assemblies, and optics-adjacent hardware with grooves, tracks, channels, and recesses that punish sloppy angles and uncontrolled wetness. It is especially useful when the contamination risk is glove proximity and solvent flooding rather than lack of reach alone.

SOSCleanroom’s relationship with ITW Texwipe supports continuity of supply and documentation discipline, reducing the risk of unplanned substitutions that change wetting behavior, extractables background, or packaging controls. That matters in regulated and standards-driven environments where documentation expectations often track FDA quality systems and methods associated with ASTM and IEST, alongside ISO cleanroom classification practices.

Operational support matters, too. Fast shipping and responsive customer service help keep validated work instructions intact by preventing “make-do” material swaps when schedules tighten.
