STX714A Sterile Alpha® Large Polyester Knit Cleanroom Swab (Rectangular Head)

STX714A Sterile Alpha® is a low-linting (no swab is truly ‘lint-free’ in every process condition), high-absorbency polyester knit cleanroom swab engineered for precision cleaning of broad, flat surfaces and controlled surface sampling in critical environments. The rectangular, double-layer 100% polyester knit head is thermally bonded to a clean, 100% virgin polypropylene handle—eliminating adhesive contamination and sealing exposed edges for cleaner, more repeatable swabbing. Each swab is gamma irradiated to a 10^-6 Sterility Assurance Level (SAL) and supplied in an individually packaged peel-apart sleeve with lot coding and expiration dating to support sterile workflows, documentation discipline, and audit-ready traceability.

Texwipe (an ITW company) differentiates itself in cleanroom swabbing by treating the swab as a controlled, engineered tool—not a commodity accessory. For sterile Alpha® polyester knit swabs like STX714A, that engineering focus centers on fabric selection and controlled laundering, thermal-bond head attachment (to avoid adhesive-driven residue risk), dimensional repeatability, and packaging designed to protect sterility at point of use while supporting documentation-driven workflows.

Sterile programs also live or die on traceability. STX714A is built around lot-coded, expiration-dated sleeves and multi-layer bagging that helps teams introduce swabs into sterile areas with less handling variability. SOSCleanroom (SOS) supports that discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs and lot traceability), and practical application guidance—so customers can standardize sterile swabs with predictable performance and procurement reliability.

• Gamma irradiated to 10^-6 Sterility Assurance Level (SAL); sterile validated according to AAMI guidelines
• 100% polyester knit head with double-layer construction for enhanced absorbency
• Thermal bond construction eliminates adhesive contamination pathways
• Cleanroom manufactured to support low levels of ions and NVR (process-relevant cleanliness control)
• Each swab individually packaged in a peel-apart sleeve for sterile point-of-use handling
• Each sleeve lot coded and marked with an expiration date for inventory control and traceability
• Fifty sleeves triple-bagged; triple-bagged inner packs shipped in a case liner (fourth layer protection)
• Tested for endotoxins, ions, and NVR for sterile-program qualification support
• 100% virgin polypropylene handle for strong chemical resistance and reduced risk of adding contaminants
• Trademarked light-green handle with “TEXWIPE” embossed on the handle as an authenticity/traceability identifier

• Cleaner swabbing baseline for critical work: Polyester knit construction and controlled processing help minimize background contribution (process-dependent), supporting sensitive sampling and cleaning validation workflows.
• Sterility assurance + documentation: Individually sleeved, lot-coded, expiration-dated packaging supports sterile introductions and audit-ready traceability.
• Broad-surface control: Large rectangular head improves coverage on flats, plates, tool faces, and smooth equipment surfaces where consistent wipe geometry matters.
• Reduced snag/abrasion risk: Knit structure is engineered to resist snagging and abrading on typical cleanroom surfaces (surface-dependent), helping reduce particle release risk.
• Chemistry versatility: Excellent chemical compatibility for common cleanroom solvents/solutions (including IPA) when verified against your process chemistry and materials-of-construction.

• Precision cleaning of broad surfaces and flat areas in ISO-class cleanrooms
• Surface sampling for cleaning validation and residue investigation workflows
• Cleaning of fixtures, plates, tooling faces, and smooth equipment exteriors
• Controlled solvent application and removal (e.g., IPA) where wipe geometry and repeatability matter
• Microelectronics, semiconductor, optics, medical device, biologics, and pharmaceutical controlled-environment cleaning steps (process-specific)
• Spot cleaning of grooves, tracks, and slots when a larger knit head improves contact area and controlled pickup

• Sleeve discipline: Open the peel-apart sleeve only when ready to use; avoid staging opened sleeves to reduce handling-driven contamination risk.
• Technique control: Use straight-line strokes and consistent pressure; avoid scrubbing motions that can re-deposit contamination.
• Swab-face management: Use the broad knit face intentionally—do not re-wipe with a loaded head. Replace the swab when pickup saturates or residues smear.
• Wet vs. controlled: If using solvent, target a controlled, repeatable wetness level; avoid over-wetting seams, joints, labels, or electrical interfaces.
• Compatibility check: Confirm solvent compatibility with the surface and swab materials; validate against your SOP and qualification method.

• Sterile vs. non-sterile (TX714A): Choose STX714A when sterile introduction, sterile validation language, and packaging-level traceability are required; choose TX714A when sterility is not required by the workflow.
• Large rectangular head advantage: Use STX714A when broad contact area improves repeatability on flat wipe points (plates, tooling faces, smooth fixtures) and when sampling coverage per swab matters.
• Head material vs. foam: Polyester knit is commonly preferred for sampling/validation neutrality and broad-surface wiping; choose sterile foam swabs when pore structure and solvent delivery characteristics better match the soil type and surface geometry.
