Texwipe STX764 Sterile Small Polyester Cleanroom Swab (Individually Wrapped) — Spun Polyester Tip, Long Polystyrene Handle

Texwipe STX764 is a sterile, individually wrapped, small-head spun polyester cleanroom swab designed for documented sampling and controlled cleaning in critical environments. It is constructed from 100% medical-grade spun polyester bonded to a long polystyrene shaft with an aqueous-based adhesive, then gamma irradiated to a 10^-6 Sterility Assurance Level (SAL) to support sterile technique, lot traceability, and expiration-date control. STX764 is frequently selected for environmental monitoring, diagnostic-style sampling, and solvent-assisted wipe steps (commonly IPA), where a narrow tip and long reach improve access into ports, joints, crevices, and equipment features while maintaining operator control. As with any fiber-based swab, performance is process-dependent (substrate texture, pressure, wetness, and stroke count), and no swab is truly ‘zero-lint’ in every condition—the goal is low-linting behavior appropriate to your risk model.

Texwipe (an ITW company) differentiates itself in contamination control by treating the swab as an engineered process tool, not a commodity. That discipline starts with controlled material selection and dimensional consistency, then extends into manufacturing methods, sterility assurance controls, and packaging designed to preserve point-of-use readiness.

In sterile sampling programs, documentation and repeatability matter as much as the swab geometry. Texwipe emphasizes sterility assurance (gamma irradiation to SAL targets), clear packaging presentation, and traceability signals that support inventory control and inspection readiness. SOSCleanroom (SOS) supports that discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs, lot traceability), and practical application support—so customers can standardize sterile swabs with predictable performance while maintaining procurement reliability and audit defensibility.

• Gamma irradiated to 10^-6 Sterility Assurance Level (SAL) in accordance with ANSI/AAMI/ISO 11137 guidance
• Individually wrapped sterile presentation supports point-of-use aseptic handling
• Lot code and expiration date clearly marked on each package (often included in barcode for inventory control)
• Certificates of Irradiation and Compliance attached to each case to confirm irradiation dose met specifications
• Pre-sterilized swabs help eliminate repackaging, documentation burden, and validation of on-site autoclaved swabs
• 100% medical-grade spun polyester head for sampling and controlled cleanup
• Long polystyrene handle improves reach and helps maintain consistent contact angle in tight features
• High-precision automated processes for consistent dimensions and repeatable technique across operators
• Clear packaging helps visibility of seal integrity and handling discipline
• Packaging labeled for global use

• Sterility assurance + documentation: Supports sterile sampling expectations with package-level traceability and expiration dating for audit-ready records
• Better access in tight geometries: Small head and long shaft reach into ports, seams, hinges, gasket lands, and recessed equipment features
• Repeatable sampling technique: Consistent dimensions help standardize contact area, stroke overlap, and pressure discipline across shifts
• Controlled solvent cleaning support: Commonly used with compatible solvents (often IPA) for targeted wipe steps and residue pickup (verify compatibility to your chemistry and SOP)
• Practical inventory control: Individually wrapped units plus case-level certification simplify introduction control and program replenishment

• Environmental monitoring and surface sampling in controlled environments
• Diagnostic-style sampling and microbiological laboratory collection workflows
• Targeted cleaning with solvents such as IPA on fixtures, touchpoints, and equipment exteriors (compatibility dependent)
• Sampling recessed areas, joints, corners, ports, and small ledges where plates and wipes do not seat reliably
• Controlled pickup of light residues where defined area, defined strokes, and defined wetting are required

• Hands-off head discipline: Handle only the shaft; avoid contacting the spun polyester tip to preserve sterile presentation and sampling integrity.
• Define area and method: For sampling, standardize a defined surface area (template where practical), fixed stroke count, fixed overlap pattern, and consistent pressure to support trendable data.
• Dampen with control (if your SOP requires): Use the approved diluent/solvent volume—wet enough for recovery, not so wet that liquid runs down the shaft or into the bond line.
• Unidirectional strokes: Use straight-line, overlapping passes; rotate/flip as instructed by your method rather than scrubbing or reworking a loaded tip.
• Material compatibility check: Because the handle is polystyrene, confirm compatibility if your procedure uses aggressive solvents; IPA is common, while stronger chemistries may require a different handle polymer.
• Immediate containment: After sampling, place the swab into the specified container/media promptly and label per your lot/area documentation practice.

• Small-head reach vs. higher-contact coverage: Choose STX764 when you need a narrow tip for tight access; select a larger-head sterile polyester swab when coverage per pass and recovery area are the priority.
• Spun polyester vs. foam/knit swabs: Spun polyester is commonly used for sampling; for scratch-sensitive optics or coating-critical surfaces, qualified foam or knit polyester swabs may offer different particle/abrasion behavior (qualify on representative coupons).
• Sterile documentation fit: If your SOP requires package-level expiration dating, case certificates, and clear lot controls, STX764 is designed around those sterile-program expectations.
