Texwipe STX761 Sterile Alpha® Polyester Knit Cleanroom Swab with Long Handle

Texwipe STX761 is a sterile, long-handle Alpha® polyester knit cleanroom swab engineered for precision cleaning and surface sampling in controlled environments where reach, repeatability, and a defensible contamination-control story matter. The cleanroom-laundered, knitted polyester head is thermally bonded (no adhesive at the head/shaft interface) to help minimize bond-line extractables variability during solvent use and to reduce fiber release pathways tied to exposed edges. STX761 is widely used for controlled cleaning and sampling of flat areas, grooves, tracks, slots, channels, tight corners, and other recessed features across industries like microelectronics, semiconductor, optics, medical devices, biologics, and pharmaceutical manufacturing. Low-linting performance is process-dependent (no swab is truly ‘lint-free’ under every surface condition and operator technique), but STX761 is built to support consistent, low-background workflows where the swab should not dominate residue, ions, endotoxin, or measurement results.

Texwipe (an ITW company) approaches cleanroom swabs as engineered contamination-control tools—controlling head substrate selection, bonding method (thermal bonding to eliminate adhesive contamination pathways), cleaning/laundering, and packaging discipline to fit sterile and controlled-environment workflows. For sterile programs like STX761, Texwipe emphasizes point-of-use sterility protection, lot-level traceability, and packaging intended to reduce variability in how swabs are introduced into critical zones.

SOSCleanroom (SOS) supports that manufacturing discipline through a working relationship focused on continuity of supply, documentation handoff (lot traceability and sterile program controls), and practical application support—so teams can standardize sterile cleanroom swabs with predictable performance and procurement reliability.

• Thermally bonded knitted Alpha® polyester head (eliminates adhesive contamination at the bond line)
• Cleanroom-laundered knit head intended to deliver low-background performance for critical cleaning and sampling
• Long, rigid polypropylene handle to extend reach and help keep gloves and sleeves out of the work zone
• Individually packaged peel-apart sleeve for point-of-use sterility protection
• Lot coded packaging and expiration date on each sleeve for inventory control and traceability
• Packaging system supports sterile-area introductions (triple-bagged inner configuration; case-liner protection)
• Gamma-irradiated and sterile validated according to AAMI guidelines
• Tested for endotoxins, ions, and non-volatile residue (NVR) as part of sterile swab program controls
• Trademarked light-green handle with “TEXWIPE” embossed on the handle (authenticity/traceability cue; verify with label + lot code)

• Sterile, point-of-use control: Individually sleeved sterile swabs with expiration dating support controlled introductions and audit narratives.
• Lower adhesive-risk profile: Thermal bonding removes a common variable in solvent-heavy work—adhesive softening, smearing, or extractables at the head/shaft interface.
• Reach and geometry control: Long handle and flexible head paddle improve access to recessed features while maintaining controlled contact pressure.
• Sensitive-surface friendly: Polyester knit is soft and nonabrasive for many optics, microelectronics, and precision hardware touchpoints (confirm suitability to your surface finish and SOP).
• Cleaner background for sampling: Often selected for surface sampling and cleaning validation workflows where neutral background contribution matters.

• Precision cleaning of grooves, tracks, slots, rails, channels, and tight corners
• Controlled solvent use (including IPA and other compatible cleanroom solvents/solutions) for maintenance, inspection, and corrective cleaning
• Surface sampling and cleaning validation sampling where a sterile barrier is required at point of use
• Environmental monitoring support workflows (as defined by your site program)
• Picking up fine powders and particulate debris in small or recessed areas
• Cleaning broad surfaces and flat areas where a long handle improves access and reduces incidental contact risk

• Sterile-open discipline: Open the peel-apart sleeve only at point of use, and avoid contact between gloves and the knit head to preserve sterile integrity.
• Use a controlled “damp” technique: Wet the knit head to your validated method (do not flood). Controlled wetness improves residue removal without driving streaking, pooling, or solvent migration into seams and joints.
• Stroke strategy: Use straight-line passes and avoid aggressive circular scrubbing—surface burrs + high pressure are common drivers of fiber release in real workflows.
• Rotate and retire: Rotate to a clean face/edge as you load soils; replace the swab when the head becomes visibly soiled, tacky, or starts to leave residue.
• Standards awareness: Align your use/qualification to your site requirements and relevant guidance (ISO: https://www.iso.org/standard/53394.html; ASTM: https://www.astm.org; IEST: https://www.iest.org; FDA: https://www.fda.gov).

• Sterile vs. non-sterile: Choose STX761 when your workflow requires point-of-use sterility, expiration dating, and sterile-program packaging controls; use a non-sterile long-handle Alpha polyester knit swab only when sterile requirements do not apply.
• When “background” is the gate: If you are running a cleaning validation protocol or analytical method where swab contribution must be tightly controlled (TOC/HPLC/UV-Vis/IMS), confirm whether a low-TOC or method-specific swab variant is required by your laboratory method.
• When ESD is the gate: If electrostatic discharge control is a selection requirement (electronics/display work), specify an ESD-safe swab family in addition to the required geometry and sterility needs.
