STX758B Sterile Micro Alpha® Polyester Knit Cleanroom Swab (Light-Green Handle)

Texwipe STX758B is a sterile, micro-size Alpha® polyester knit cleanroom swab engineered for precision spot cleaning and controlled swabbing in tight geometries—grooves, tracks, slots, ports, ferrules, recesses, and other small features where wipes cannot maintain contact or consistent stroke discipline. The swab head is cleanroom laundered 100% polyester knit and thermally bonded to a virgin polypropylene handle to seal exposed edges and eliminate adhesive contamination. Performance intent is low-linting behavior (no swab is truly ‘zero-lint’ in every process condition), ultra-low residue contribution (low NVR) and low ionic background for critical cleaning, surface sampling, and cleaning-validation workflows that depend on repeatability and defensible documentation.

Sterile-program note: STX758B is individually sleeved with lot coding and package-level expiration dating, then triple-bagged in 50-sleeve inner bags to support staged sterile introduction. Teams often standardize STX758B when micro-access cleaning must remain sterile and audit-ready (controlled transfer, lot traceability, expiration control, and consistent swab geometry).

About the Manufacturer: 

Texwipe (an ITW company) treats the cleanroom swab as a controlled, engineered tool—not a commodity. For Alpha® polyester knit swabs like STX758B, that shows up in the knit substrate selection, precision geometry, cleanroom processing/laundering, and complete thermal bond construction designed to remove one of the most common contamination variables: adhesive chemistry at the head-to-handle interface.

 

For sterile programs, Texwipe pairs that construction discipline with packaging and documentation controls (individual sleeves, lot coding, expiration dating, and multi-layer bagging) intended to support staged transfer into sterile or higher-control zones. SOSCleanroom (SOS) supports that discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (lot traceability), and practical application support—so customers can standardize sterile micro-swabbing with predictable performance, reliable replenishment, and audit readiness.

STX758B Features:
  • Micro-size Alpha® polyester knit head for precision access in tight geometries
  • Complete thermal bond construction eliminates adhesive contamination and helps seal exposed edges
  • Cleanroom processed/laundered head engineered for low background contribution (low NVR / low ions—typical values are used for baseline qualification)
  • 100% virgin polypropylene handle for broad chemical resistance and reduced risk of handle-sourced contaminants
  • Trademarked light-green handle color convention with “TEXWIPE” embossed on the handle for traceability cues
  • Each swab individually packaged in a peel-apart sleeve
  • Each sleeve lot coded and marked with an expiration date for inventory control
  • Fifty (50) sleeves triple-bagged for staged sterile introduction; triple-bagged bags packed in a case liner as an additional protective layer
  • Gamma irradiated to 10-6 SAL and sterile validated according to AAMI guidelines
  • Tested for endotoxins, ions, and Non-Volatile Residue (NVR)
STX758B Benefits:
  • Micro-access control: The ~3.2 mm head width and compact overall length help maintain contact and single-direction stroke control inside narrow channels, connector shells, ferrules, and recessed features
  • Sterile introduction + documentation: Individual sleeves, lot coding, expiration dating, and multi-layer bagging support controlled transfer, traceability, and investigation readiness
  • Reduced chemistry variables: Thermal bonding eliminates adhesive contamination pathways that can show up as streaks, residue, or analytical noise
  • Low-linting performance: Knit polyester is selected for controlled shedding behavior (process-dependent) and resistance to snagging/abrading
  • Low residue risk: Low NVR positioning helps reduce film/haze risk when using volatile solvents (verify against your method when validation-sensitive)
  • Broad solvent compatibility: Polyester knit head + polypropylene handle are commonly used with IPA and many cleanroom-compatible solvents/solutions (confirm compatibility to your chemistry and SOP)
Common Applications:
  • Precision spot cleaning of grooves, tracks, slots, ports, and other small spaces
  • Cleaning of connector shells, ferrules, optic mounts, sensor pockets, and tight mechanical interfaces
  • Applying and removing lubricants, adhesives, and process solutions in a critical clean environment
  • Solvent use (such as IPA) for controlled application/removal and residue-sensitive wipe points
  • Surface sampling and cleaning validation work where neutral background contribution matters
  • Environmental monitoring and controlled swabbing steps that require sterile packaging discipline
Best-Practice Use:
  • Open-and-use discipline: Open the peel-apart sleeve only when ready to swab; minimize open exposure time in the hood/clean zone.
  • Staged sterile transfer: Use the multi-layer bagging as intended (de-bag outer layers outside the critical zone; introduce inner layers per your gowning/transfer SOP).
  • Control wetness: For solvent swabbing, dampen the head and remove excess. Over-wetting turns a micro swab into a solvent delivery tool that can drive residues into corners.
  • Single-pass technique: Use straight-line strokes with parallel overlap. Rotate the swab head/faces instead of re-wiping with a loaded surface.
  • Low-pressure contact: Use the lowest pressure that maintains full head contact—especially on coated optics, polished metals, and soft polymers.
  • Aliquot discipline: Avoid re-dipping into a shared solvent reservoir. Use single-use aliquots or controlled dispense to reduce cross-contamination.
  • Change-out triggers: Replace the swab when the head shows visible soil loading, tackiness, streaking, or loss of contact control.
Selection Notes (STX758B vs. Other Options)
  • Sterile vs. non-sterile (TX758B): Choose STX758B when sterile introduction, lot traceability, and expiration control are required by the workflow; choose TX758B when sterile processing is not required.
  • Micro head vs. larger heads: Use STX758B for the smallest wipe points (tight channels, ports, ferrules, fine recesses). Step up to larger Alpha® or CleanFoam® heads when coverage per swab matters more than micro access.
  • Thermal bond preference: When residue risk and analytical sensitivity are high, thermal bonding reduces an entire class of “unknown variables” associated with adhesives.
  • Documentation expectations: If your program is audit-facing (sterile compounding, aseptic processing, medical device, biologics), sleeve-level lot and expiration marking simplifies investigation and inventory controls.

Texwipe STX758B Sterile Micro Alpha® Polyester Knit Cleanroom Swab for Tight-Geometry Spot Cleaning and Sterile, Lot-Controlled Swabbing

Texwipe STX758B is a sterile, micro-size Alpha® polyester knit cleanroom swab used for controlled swabbing where access geometry is small and method repeatability matters (grooves, tracks, slots, ports, ferrules, recesses, and similar features). The knit polyester head is cleanroom laundered and thermally bonded to a virgin polypropylene handle, a construction approach commonly selected to reduce variables associated with adhesive bond lines in residue-sensitive programs. In practice, this SKU is often positioned for precision cleaning, SOP-defined surface sampling, and cleaning-validation related workflows where the swab’s background contribution (particles/residues/ions) and consistent geometry are part of the qualification rationale. For sterile use, operational control depends on sterile barrier integrity, aseptic presentation at point-of-use, and disciplined change-out triggers when the head loads, is over-wet, or contacts non-controlled surfaces. Because “low-lint” performance is surface- and technique-dependent, programs typically standardize solvent loading, stroke count, and head rotation/face-change practices to reduce variability and rework.

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, ports, ferrules, recesses, and other tight geometries where wipers cannot maintain controlled contact
  • Controlled solvent application/removal (IPA, WFI, validated disinfectant, engineered solvent per SOP) using defined “damp” loading and face rotation
  • Removing particulate or residue from tool interfaces, fixtures, connector shells, and small mechanical interfaces where micro-contact control reduces rework risk
  • Cleaning on sensitive surfaces where broad cloth/wiper contact is too aggressive or too difficult to control
  • 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 polypropylene handle to the solvent and contact time.
  • 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.
