TX718 Alpha Polyester Knit Large Sampling Cleanroom Swab with Notched Break-Away Handle

Texwipe TX718 is a low-linting (no swab is truly ‘zero-lint’ in every process condition), solvent-compatible cleanroom sampling swab engineered for surface residue collection and cleaning validation workflows using HPLC/UV-Vis and other chromatography/separation techniques. It uses a 100% low titanium dioxide polyester knit swab head for controlled residue pickup and release during extraction, paired with a translucent 100% polypropylene handle (no colorants / no titanium dioxide) to help reduce analytical interferences. A complete thermal bond construction eliminates adhesive-related contamination pathways, and the notched break-away handle is designed so the swab head can be placed into a vial with minimal handling—a practical advantage when sampling has to survive an audit trail.

Cleaning-validation note: TX718 is typically selected when teams need a purpose-built sampling swab that supports repeatable recovery, controlled background contribution, and lot-coded traceability for regulated documentation and investigation readiness.

About the Manufacturer: 

Texwipe (an ITW company) differentiates itself in cleanroom sampling by treating the swab as an engineered, method-sensitive device—not a generic consumable. For cleaning validation and residue recovery, controlling background contribution (organics, ions, and non-volatile residue), bonding method (thermal vs. adhesive), and handle chemistry (solvent resistance and low-interference materials) can materially affect the quality of HPLC/UV-Vis data and the defensibility of a validation package.

 

TX718 is positioned for solvent-based surface sampling and cleaning validation use, with a low titanium dioxide polyester knit head and a translucent polypropylene handle designed to reduce potential interferences. SOSCleanroom (SOS) supports this validation-driven purchasing model with a close working relationship with Texwipe focused on continuity of supply, lot/documentation handoff, and practical application support—so customers can standardize sampling materials with predictable performance while maintaining procurement reliability and audit readiness.

TX718 Features:
  • Designed for surface sampling and cleaning validation workflows using HPLC/UV-Vis and other chromatography/separation techniques
  • 100% low titanium dioxide polyester knit swab head for controlled residue pickup and release during extraction
  • Complete thermal bond construction eliminates adhesive contamination pathways
  • Notched break-away handle helps place the head into a vial with minimal handling or contamination risk
  • Translucent 100% polypropylene handle with no colorants / no titanium dioxide for excellent chemical resistance and reduced potential interferences
  • Designed for organic solvent-based applications (may exhibit hydrophilic behavior with water)
  • Lot coded for traceability and quality control
  • Handle marking: embossed with “CleanTips® Sampling Swab” for identification and traceability
  • Included in Texwipe TX3360 cleaning validation kit (validation program alignment)
TX718 Benefits:
  • Cleaner analytical signal: Low titanium dioxide polyester knit construction is intended to help reduce background contribution that can limit sensitivity in UV-Vis and chromatography-based residue methods (process- and method-dependent)
  • Reduced handling risk: The notched break-away handle supports vial transfer with less touch time—supporting chain-of-custody discipline and minimizing incidental contamination
  • No-adhesive construction: Thermal bonding removes a common source of extractables associated with adhesives, improving confidence in blanks and routine trending
  • Solvent compatibility: Polypropylene handle + knit polyester head are designed for solvent-based sampling and extraction workflows (verify compatibility to your solvent system and SOP)
  • Audit-ready traceability: Lot coding supports investigations, change control, and documentation expectations in regulated cleaning validation programs
Common Applications:
  • Surface sampling as part of a cleaning validation protocol with solvent-based chemistries
  • Pharmaceutical manufacturing cleaning validation analysis with HPLC/UV-Vis detection systems
  • Residue collection from defined surface areas (equipment walls, corners, radii, seams, gaskets) for extraction and lab analysis
  • Surface cleaning as part of surface preparation prior to sampling or inspection
  • Controlled swabbing in biotech, pharma, and analytical lab workflows where background contribution and repeatability matter
Best-Practice Use:
  • Control the method variables: Standardize the sampled area, stroke count, pressure discipline, and wipe path (straight-line passes with overlap are easier to reproduce than circular scrubbing).
  • Wetness discipline: Use a defined pre-wet step with validated solvent volume and contact time; damp lifts/captures while over-wet can spread residue outside the sampled area.
  • Rotate faces, avoid re-deposit: Rotate the head as it loads; do not keep swabbing with a saturated face that can re-deposit contamination.
  • Vial transfer with minimal handling: Use the notched break-away feature to place the head into the vial with reduced touch time; avoid contact with vial rims and non-sampled surfaces.
  • Run blanks and trend: Include a swab blank per lot (extracted swab that never touched the surface) to quantify background and support investigations if peaks drift.
Selection Notes (TX718 vs. Other Options)
  • Cleaning validation vs. general-purpose swabbing: Choose TX718 when your swab is part of an analytical method (HPLC/UV-Vis / chromatography) and swab background and repeatability can limit defensible results; use general-purpose cleanroom swabs when you are not extracting/quantifying residues.
  • Solvent-based workflows: TX718 is designed for organic solvent-based sampling/extraction. Confirm compatibility to your solvent system, residue chemistry, and hold-time requirements.
  • Handle length and paddle geometry: The large flat paddle head and long handle are suited for defined area sampling on equipment surfaces and access into seams/corners while maintaining operator control.

Texwipe TX718 Alpha® Polyester Knit Large Swab with Notched Handle (Non-Sterile) — Large Knit Contact for Broad Features with Improved Grip Control to Support Repeatable, Unidirectional Wiping

Texwipe’s TX718 Alpha® Polyester Knit Large Swab with Notched Handle is a cleanroom-processed, non-sterile swab selected when a larger knit head provides efficient coverage while maintaining localized control versus a full wiper. Polyester knit heads are commonly used in controlled environments for durability and consistent wiping behavior on tool faces, housings, rails, and other broader features where smaller swabs require excessive passes. The notched handle can support repeatable grip orientation, which helps maintain a consistent approach angle and pressure during unidirectional strokes. In many operations, this type of swab is used for cleaning larger interfaces, removing localized films, and controlling solvent application/removal where the method requires a defined contact path. As head surface area increases, loading can occur quickly; SOPs often define strokes-per-face and discard cadence to reduce re-deposition and variability. For controlled or validated programs, confirm dimensions, construction, residue positioning (NVR/ions/extractables), and packaging configuration using current manufacturer documentation and lot records.

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 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.

Control point: Larger knit heads can improve efficiency but increase the chance of unintended contact. Define the wiping lane (contact path), grip orientation, and face-change cadence in the SOP.

What this swab is designed to do (typical use cases)
  • Precision cleaning on broader features: tooling faces, housings, rails, seal lands, and component edges
  • Controlled solvent application/removal (IPA, acetone, engineered solvent per SOP) with defined wetness targets and unidirectional wiping lanes
  • Removing localized films or particulate where small swabs require excessive passes and increase variability risk
  • Detail cleaning where cloth/wiper contact is too broad but larger swab coverage improves efficiency
  • Sampling/verification workflows only if applicable and permitted by your SOP

Selection note: Large knit swabs are commonly chosen when coverage and durability matter. Validate against your surface finish and cleaning chemistry, then standardize grip orientation, stroke limits, and discard cadence.

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. Control wetness: use a defined “damp” loading (not dripping). Excess solvent can widen the wiping lane and increase residue streaking.
  3. Directional strokes: use controlled, unidirectional passes with even pressure. Avoid scrubbing that redistributes contamination.
  4. Use the notch for repeatability: maintain consistent grip orientation and keep the same face in contact until you intentionally rotate/advance.
  5. Change-out triggers: discard when the head loads, frays, sheds, or residue transfer is observed.
  6. Waste discipline: discard immediately into the designated waste stream (do not stage used swabs on benches).

Method standardization tip: Define a wiping lane and a “strokes-per-face” rule; rotate the head on a schedule rather than by feel.

Misuse controls & when not to use
  • If sterility is required: do not substitute non-sterile swabs for sterile workflows.
  • 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 construction/head 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.
