Texwipe STX763 Sterile Gamma Irradiated Polyester Swab (Individually Wrapped, Lot/Expiration Marked)

Texwipe STX763 is a sterile, gamma irradiated spun polyester swab designed for diagnostic sampling, environmental monitoring, and controlled solvent-assisted swabbing in regulated and contamination-sensitive workflows. Each swab uses a 100% medical-grade spun polyester head securely bonded to a long polystyrene shaft with an aqueous (water-based) adhesive to deliver consistent geometry and repeatable sampling contact on seams, ports, touchpoints, recessed features, and irregular surfaces. STX763 is supplied individually wrapped in easy-open, clear packaging that supports point-of-use sterile presentation while providing visibility of seal integrity. Low-linting performance is process-dependent (no swab is truly ‘lint-free’ under every surface condition and operator technique), but STX763 is engineered to support clean, defensible swabbing where traceability and sterility controls are part of the method—not an afterthought.

Texwipe (an ITW company) is a global leader in contamination-control consumables, including sterile swabs engineered around repeatable geometry, controlled packaging, and documentation discipline. In sterile spun-swab programs like STX763, Texwipe emphasizes point-of-use sterile presentation (individually wrapped units), lot/expiration marking for traceability, and case-level certificates that support regulated workflows and inspection-ready records.

SOSCleanroom (SOS) supports sterile sampling and monitoring programs with continuity of supply, clean documentation handoff, and practical selection guidance so teams can standardize swabbing methods without uncontrolled substitutions that increase variability.

• Gamma irradiated to a Sterility Assurance Level of 10^-6 (SAL) in accordance with ANSI/AAMI/ISO 11137
• Individually wrapped, easy-open peel-apart sleeve supports sterile presentation at point of use
• Clear unit packaging allows visibility of seal integrity
• 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
• Pre-sterilized swabs help eliminate repackaging, documentation burden, and validation work tied to in-house sterilization steps
• Packaging labeled for global use
• 100% medical-grade spun polyester head bonded to long polystyrene shaft for consistent, repeatable sampling geometry

• Audit-ready sterility claim: Defined SAL + standard-aligned irradiation helps support regulated sampling and monitoring programs
• Traceability you can actually use: Unit-level lot and expiration marks make chain-of-custody and investigation work faster and cleaner
• Reliable access for real sampling: Large spun-polyester head on a long polystyrene shaft improves reach and consistent approach angle across operators
• Controlled swabbing with common solvents: Frequently used with IPA for solvent-assisted swabbing (verify compatibility and dwell-time limits for your chemistry)
• Reduced handling variability: Individually wrapped sterile units help prevent compromise caused by repeated bag opening and rehandling at the bench

• Diagnostic sampling and specimen/surface collection workflows (as defined by your program)
• Environmental monitoring swabbing (surface sampling in controlled areas)
• Controlled cleaning with solvents such as IPA (spot cleaning and wipe-point swabbing)
• Surface sampling of seams, ports, recessed features, irregular geometries, and touch surfaces
• Picking up fine powders and particulate in small or hard-to-reach areas

• Open-and-use discipline: Open the sleeve only at point of use and present the swab without contacting the head to preserve sterile integrity.
• Define the method: For trending or investigation work, standardize the swabbed area, stroke count, stroke direction, and pressure expectations so results are comparable.
• Control wetness: Damp lifts and captures; over-wet spreads and can drive material toward edges, seams, and the bond line. Avoid flooding the head.
• Stroke strategy: Use single-direction, parallel, overlapping strokes. Avoid circular scrubbing unless your written method requires it.
• No re-dipping: Do not return a used swab to a shared solvent reservoir. Use controlled aliquots/dispense to reduce cross-contamination.
• Chemistry awareness: Polyester is broadly compatible with many common solutions, but polystyrene shafts may be challenged by aggressive chemistries (qualify your solvent, dwell time, and temperature to your SOP).
• Standards awareness: Align sampling, documentation, and controlled-environment expectations to your program (ISO: https://www.iso.org/standard/53394.html; FDA: https://www.fda.gov; ASTM: https://www.astm.org; IEST: https://www.iest.org).

• Sampling swab vs. ultra-critical residue control: STX763 is a sterile spun polyester swab with an adhesive bond. For ultra-low residue cleaning or validation-sensitive work, confirm whether your method requires a different swab construction (e.g., knit/foam with thermal bonding or method-specific low-background variants).
• Geometry fit matters: STX763 is a large-head sterile polyester swab for broad contact and recoverability in real sampling. If your target features are narrower channels, micro-ports, or very tight recesses, a smaller head geometry may improve stroke control and access.
• Solvent strength and shaft compatibility: If your SOP calls for stronger solvents than IPA, qualify the polystyrene shaft under real dwell time and temperature, or specify a handle material better suited to that chemistry.
• Documentation expectations: Unit-level lot/expiration marking is a major operational advantage when sampling results drive investigations, batch decisions, or regulatory reporting.
