Texwipe STX761 Sterile Alpha® Polyester Knit Cleanroom Swab with Long Handle

Texwipe STX761 is a sterile, long-handle Alpha® polyester knit cleanroom swab engineered for precision cleaning and surface sampling in controlled environments where reach, repeatability, and a defensible contamination-control story matter. The cleanroom-laundered, knitted polyester head is thermally bonded (no adhesive at the head/shaft interface) to help minimize bond-line extractables variability during solvent use and to reduce fiber release pathways tied to exposed edges. STX761 is widely used for controlled cleaning and sampling of flat areas, grooves, tracks, slots, channels, tight corners, and other recessed features across industries like microelectronics, semiconductor, optics, medical devices, biologics, and pharmaceutical manufacturing. Low-linting performance is process-dependent (no swab is truly ‘lint-free’ under every surface condition and operator technique), but STX761 is built to support consistent, low-background workflows where the swab should not dominate residue, ions, endotoxin, or measurement results.

Sterile-program note: STX761 is individually sleeved with lot code and expiration dating to support audit readiness and sterile-area introductions. Sleeves are organized in sterile-friendly packaging (triple-bagged inner configuration) to reduce handling-driven variability at point of use and to help teams keep “last touch” controls consistent from operator to operator.

About the Manufacturer: 

Texwipe (an ITW company) approaches cleanroom swabs as engineered contamination-control tools—controlling head substrate selection, bonding method (thermal bonding to eliminate adhesive contamination pathways), cleaning/laundering, and packaging discipline to fit sterile and controlled-environment workflows. For sterile programs like STX761, Texwipe emphasizes point-of-use sterility protection, lot-level traceability, and packaging intended to reduce variability in how swabs are introduced into critical zones.

 

SOSCleanroom (SOS) supports that manufacturing discipline through a working relationship focused on continuity of supply, documentation handoff (lot traceability and sterile program controls), and practical application support—so teams can standardize sterile cleanroom swabs with predictable performance and procurement reliability.

STX761 Features:
  • Thermally bonded knitted Alpha® polyester head (eliminates adhesive contamination at the bond line)
  • Cleanroom-laundered knit head intended to deliver low-background performance for critical cleaning and sampling
  • Long, rigid polypropylene handle to extend reach and help keep gloves and sleeves out of the work zone
  • Individually packaged peel-apart sleeve for point-of-use sterility protection
  • Lot coded packaging and expiration date on each sleeve for inventory control and traceability
  • Packaging system supports sterile-area introductions (triple-bagged inner configuration; case-liner protection)
  • Gamma-irradiated and sterile validated according to AAMI guidelines
  • Tested for endotoxins, ions, and non-volatile residue (NVR) as part of sterile swab program controls
  • Trademarked light-green handle with “TEXWIPE” embossed on the handle (authenticity/traceability cue; verify with label + lot code)
STX761 Benefits:
  • Sterile, point-of-use control: Individually sleeved sterile swabs with expiration dating support controlled introductions and audit narratives.
  • Lower adhesive-risk profile: Thermal bonding removes a common variable in solvent-heavy work—adhesive softening, smearing, or extractables at the head/shaft interface.
  • Reach and geometry control: Long handle and flexible head paddle improve access to recessed features while maintaining controlled contact pressure.
  • Sensitive-surface friendly: Polyester knit is soft and nonabrasive for many optics, microelectronics, and precision hardware touchpoints (confirm suitability to your surface finish and SOP).
  • Cleaner background for sampling: Often selected for surface sampling and cleaning validation workflows where neutral background contribution matters.
Common Applications:
  • Precision cleaning of grooves, tracks, slots, rails, channels, and tight corners
  • Controlled solvent use (including IPA and other compatible cleanroom solvents/solutions) for maintenance, inspection, and corrective cleaning
  • Surface sampling and cleaning validation sampling where a sterile barrier is required at point of use
  • Environmental monitoring support workflows (as defined by your site program)
  • Picking up fine powders and particulate debris in small or recessed areas
  • Cleaning broad surfaces and flat areas where a long handle improves access and reduces incidental contact risk
Best-Practice Use:
  • Sterile-open discipline: Open the peel-apart sleeve only at point of use, and avoid contact between gloves and the knit head to preserve sterile integrity.
  • Use a controlled “damp” technique: Wet the knit head to your validated method (do not flood). Controlled wetness improves residue removal without driving streaking, pooling, or solvent migration into seams and joints.
  • Stroke strategy: Use straight-line passes and avoid aggressive circular scrubbing—surface burrs + high pressure are common drivers of fiber release in real workflows.
  • Rotate and retire: Rotate to a clean face/edge as you load soils; replace the swab when the head becomes visibly soiled, tacky, or starts to leave residue.
  • Standards awareness: Align your use/qualification to your site requirements and relevant guidance (ISO: https://www.iso.org/standard/53394.html; ASTM: https://www.astm.org; IEST: https://www.iest.org; FDA: https://www.fda.gov).
Selection Notes (STX761 vs. Other Options)
  • Sterile vs. non-sterile: Choose STX761 when your workflow requires point-of-use sterility, expiration dating, and sterile-program packaging controls; use a non-sterile long-handle Alpha polyester knit swab only when sterile requirements do not apply.
  • When “background” is the gate: If you are running a cleaning validation protocol or analytical method where swab contribution must be tightly controlled (TOC/HPLC/UV-Vis/IMS), confirm whether a low-TOC or method-specific swab variant is required by your laboratory method.
  • When ESD is the gate: If electrostatic discharge control is a selection requirement (electronics/display work), specify an ESD-safe swab family in addition to the required geometry and sterility needs.

Texwipe STX761 Sterile Alpha® Polyester Knit Cleanroom Swab with Long Handle for Reach, Repeatability, and Controlled Solvent Technique

Texwipe STX761 is a sterile, long-handle Alpha® polyester knit cleanroom swab used for precision cleaning and SOP-defined surface sampling in controlled environments where reach and repeatable technique matter. The double-layer knitted polyester head is thermally bonded (no adhesive at the head/shaft interface), which can help reduce bond-line variability during solvent use in programs that monitor residues and carryover. The long handle and flexible head paddle support access to recessed or hard-to-reach features (grooves, tracks, slots, channels, tight corners) while keeping contact area small enough for controlled stroke discipline. For sterile workflows, operational control should include sterile barrier integrity checks, aseptic presentation, and defined change-out triggers at point-of-use. Because outcomes can drift when operators increase force at full reach, many programs standardize solvent type, wetness target (“damp film”), and stroke count per feature. If packaging integrity is questionable, or if the swab head contacts a non-sterile surface, discard per SOP to protect the sterile field and method consistency.

Operations takeaway: In cleanrooms, swabs are a precision tool. The outcome depends on head material, solvent loading, stroke discipline, and single-use/change-out rules.

ISO-first context: where swabs fit in cleanroom operations control

ISO 14644-5:2025 places cleaning and handling activities under a documented Operations Control Programme (OCP). Swabs belong in that system because they directly influence localized contamination (particles, fibers, residues, and solvent carryover). Where swabs are used for precision cleaning (e.g., corners, ports, fixtures) or verification-related activities, the method should be written, trained, and repeatable: approved solvent, defined wetness, defined motion (stroke count/direction), and defined change-out triggers. For sterile swab workflows, the OCP should also address sterile barrier integrity, aseptic presentation, and change-out discipline at point-of-use.

Control point: Sterile consumables reduce risk only if the sterile barrier is protected until use. If packaging integrity is questionable, discard per SOP.

What this swab is designed to do (typical use cases)
  • Precision cleaning in small areas: grooves, tracks, slots, channels, tight corners, ports, and recessed features where reach and controlled contact matter
  • Controlled solvent application/removal (IPA, WFI, validated disinfectant, engineered solvent per SOP) using defined wetness targets
  • Removing particulate or residue from tool interfaces, fixtures, and features where wiper contact is too broad
  • Cleaning on film- or finish-sensitive surfaces where “damp film” technique and short unidirectional strokes help reduce pooling and streaking
  • Sampling/verification workflows only if applicable and permitted by your SOP

Selection note: Match the swab head material to the task and chemistry, then validate to your surface and process. For sterile workflows, also standardize sterile presentation and change-out rules in the SOP.

Best-practice use (reduce residues, particles, and rework)
  1. Control introduction: bring swabs into the cleanroom per OCP rules (outer packaging removal, staging, storage).
  2. Verify sterile barrier: inspect sterile packaging integrity prior to entry and prior to use; discard per SOP if compromised.
  3. Aseptic presentation: open and present the swab per SOP to avoid contacting the head and to protect the sterile field.
  4. Control wetness: use a defined “damp” loading (not dripping). Excess liquid is a primary cause of residue streaking and pooling.
  5. Directional strokes: use short, controlled, unidirectional strokes. Avoid scrubbing that redistributes contamination.
  6. Rotate the head: present a clean face/edge as you move; do not keep wiping with a loaded surface.
  7. Change-out triggers: discard when the head loads, frays, sheds, is solvent-overloaded, or contacts a non-sterile surface.
  8. Waste discipline: discard immediately into the designated waste stream (do not stage used swabs on benches).

Method standardization tip: If outcomes vary, lock three variables: solvent used, wetness target, and stroke count per feature.

Misuse controls & when not to use
  • If sterility is required: do not substitute non-sterile swabs for sterile workflows.
  • If sterile barrier is compromised: discard; do not attempt to “wipe clean” and continue.
  • If you are sampling for validation: do not substitute cleaning swabs for protocol-defined sampling devices and methods.
  • If the chemistry is aggressive: verify compatibility of the knit head construction and handle material to the solvent and contact time; validate to your program.
  • If ESD is critical: use an ESD-safe swab/handle where required and validate resistance/grounding to your program.
Recommended glove pairing (cleanroom handling discipline)

Pair sterile precision swabbing with sterile gloves and sterile wipers that align to your room classification and aseptic handling SOPs. The selections below are common pairings for sterile workflows; final selection should be validated to your process, surfaces, and current manufacturer documentation.

Glove discipline: Change gloves when contaminated, torn, solvent-wet, after contacting non-controlled surfaces, or when required by aseptic change-out intervals in your SOP.
