STX708A Sterile CleanFoam® Circular-Head Cleanroom Swab (100 PPI Polyurethane Foam, Individually Wrapped, Gamma Irradiated SAL 10-6)

Texwipe STX708A is a sterile circular-head foam cleanroom swab designed for environmental monitoring, diagnostic sampling, and controlled cleaning on curved or irregular surfaces where a rectangular head can skip edges or miss contact on radii. The head is constructed from high-quality 100 PPI polyurethane CleanFoam® and joined to a long, easy-grip polypropylene handle using complete thermal bond construction to eliminate adhesive contamination at the bond line. Each swab is individually wrapped for point-of-use sterility and is gamma irradiated to a 10-6 Sterility Assurance Level (SAL) in accordance with ANSI/AAMI/ISO 11137. In practical cleanroom use, foam swabs are selected for low-linting performance (no swab is truly ‘lint-free’ in every process condition), solvent pickup/control, and consistent contact on complex geometries—while sterile packaging, lot traceability, and expiration dating help keep sampling workflows defensible and audit-ready.

Sterile-program note: STX708A is widely selected when teams need a sterile, ready-to-use circular foam swab with package-level lot coding and expiration dating for cleanroom sampling and controlled cleaning steps where chain-of-custody, repeatability, and seal-integrity checks matter at the point of use.

About the Manufacturer: 

Texwipe (an ITW company) engineers sterile swabs as controlled process tools: consistent foam pore structure (100 PPI), thermal-bond construction to remove adhesive contamination mechanisms, automated manufacturing for repeatable tolerances, and sterile packaging features designed to preserve point-of-use sterility while enabling practical seal-integrity checks. For sterile foam swab programs, documentation discipline (irradiation and compliance certificates) and package-level traceability support audit readiness in regulated and validation-sensitive environments.

 

SOSCleanroom (SOS) supports that manufacturing discipline with a close working relationship with Texwipe focused on continuity of supply, documentation-forward order handling (lot traceability support), and practical application guidance—so customers can standardize sterile sampling and cleaning steps without uncontrolled substitutions.

  • Individually wrapped, easy-open sterile sleeves support point-of-use sterility
  • Clear packaging supports visual confirmation of seal integrity before introduction into critical zones
  • Lot code and expiration date clearly marked on each package and included in barcode for inventory control
  • Certificates of Irradiation and Compliance attached to each case confirm irradiation dose met specifications
  • 100 PPI polyurethane CleanFoam® circular head supports controlled contact on curved/irregular surfaces
  • Complete thermal bond construction eliminates adhesive contamination at the head/handle interface
  • Made to exacting and consistent tolerances using high-precision automated processes
  • Packaging labeled for global use (useful for multi-site programs)
STX708A Benefits:
  • Sterile sampling you can defend: Individually wrapped sterile presentation with lot/expiration markings supports chain-of-custody and investigation readiness
  • Curved-surface coverage: Circular foam geometry improves contact on radii, joints, and intersecting features where flat faces can miss edges
  • Adhesive-free bond line: Thermal bonding reduces a common residue/extractables risk when solvents are used or when pressure is applied at corners
  • Controlled solvent handling: Foam readily absorbs compatible solutions and solvents for damp (controlled) wipe passes and localized cleanup
  • Reduced method variability: Consistent dimensions and packaging discipline help reduce operator-to-operator drift in sampling and cleaning steps
  • Qualification-friendly approach: Typical background contamination values (ions and NVR) are used in many programs as starting baselines for method development (confirm fit to your acceptance criteria)
Common Applications:
  • Environmental monitoring surface sampling
  • Diagnostic sampling and general collection workflows in controlled environments
  • Cleaning with compatible solutions and solvents (verify compatibility to your chemistry and SOP)
  • Picking up fine powders and localized particulate pickup
  • Curved, radiused, or irregular geometries where circular contact improves consistency
Best-Practice Use:
  • Define the intent (sampling vs. cleaning): Sampling priorities are consistent recovery and controlled contact area; cleaning priorities are controlled removal without redeposition. Align technique and wetting to the objective.
  • Open-and-use discipline: Open the sterile sleeve only when ready to sample/clean; avoid staging opened swabs to reduce handling-driven contamination.
  • Wetness control: In many precision cleaning steps, damp is the control point. Over-wetting can flood features, spread dissolved residues, and create dry-down marks.
  • Stroke discipline: Use one-direction strokes with overlapping passes; avoid circular scrubbing unless a written procedure requires it.
  • Face rotation and change-outs: Foam loads quickly. Rotate the head surface aggressively and replace early to prevent streaking or redeposit.
  • No shared-reservoir re-dip: Do not re-dip a used swab into a shared solvent reservoir; dispense fresh solution or use controlled single-use aliquots.
  • Standards awareness: Align cleanroom classification language and documentation to ISO cleanroom conventions when applicable (ISO: https://www.iso.org/standard/53394.html). For regulated programs, maintain appropriate documentation posture (FDA: https://www.fda.gov; ASTM: https://www.astm.org; IEST: https://www.iest.org).
Selection Notes (STX708A vs. Other Options)
  • Sterile vs. non-sterile (TX708A): Choose STX708A when sterile handling, sterile documentation, and package-level traceability are required; choose a non-sterile equivalent when sterility is not required by the workflow.
  • Circular vs. rectangular head: Choose the circular head when radii and curved surfaces drive contact quality; use a rectangular head when edge definition and flat-face coverage are the priority.
  • Foam vs. fibrous heads: Foam is commonly selected for low-linting cleaning and controlled solvent handling; fibrous heads can be preferred for certain recovery or abrasion behaviors. Match head material to your method sensitivity and acceptance criteria.
  • Thermal bond matters in solvent steps: If your process uses solvents and pressure in corners, adhesive-free thermal bonding reduces a common failure mode (bond-line residue or softening).

Texwipe STX708A Sterile CleanFoam® Swab with Circular Head for Controlled Point Cleaning in Aseptic Areas

The Texwipe STX708A Sterile CleanFoam® Swab is a sterile, cleanroom-positioned foam swab designed for controlled, single-use precision cleaning in aseptic and critical environments. Its circular foam head supports stable contact on localized wipe points and curved or rounded features where a defined, small contact face is beneficial for repeatable technique. The rigid handle helps maintain controlled pressure and reach when cleaning ports, tool interfaces, fixtures, small recesses, and other tight geometries where full-size wipers are too broad. In sterile workflows, performance is tied to disciplined sterile barrier handling and aseptic presentation at point-of-use, plus defined solvent selection and loading (target “damp,” not dripping). To reduce redeposition risk, programs typically specify unidirectional strokes, rotation to a clean face, and clear change-out triggers. If the sterile barrier is compromised, or if the head contacts a non-sterile surface, discard per SOP to protect the process and sterile field.

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.

Specifications (SKU controls for RFQs, SOPs, and receiving)

What this swab is designed to do (typical use cases)
  • Precision cleaning in small areas: ports, corners, recesses, fixtures, connectors, and rounded features where a circular contact face improves control
  • Controlled solvent application/removal (IPA, WFI, validated disinfectant, engineered solvent per SOP)
  • Removing particulate or residue from tool interfaces and fixtures where localized control reduces over-contact
  • Cleaning on sensitive surfaces where cloth/wiper contact is too broad and swab-level control supports repeatability
  • 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 head adhesive/bond and handle material to the solvent.
  • 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.
