TX3221 Sterile Vertex 11" x 11" Polyester 2-Ply Sealed Edge Cleanroom Wiper

TX3221 Sterile Vertex is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), two-ply 100% continuous-filament polyester knit wiper with sealed edges, supplied sterile for critical wipe-downs, spill control, and solution application in controlled environments. It is engineered for high sorption capacity while minimizing edge-related particle/fiber release risk during wet work and repeated wipe strokes.

• Size: 11" x 11" (28 cm x 28 cm) nominal
• Material: 100% continuous-filament polyester knit (two-ply)
• Type: Dry wiper

• Packaging (inner): 100 wipers/bag (5 inner bags of 20 wipers)
• Packaging (case): 5 bags/case (500 wipers total/case)
• Bagging: Triple-bagged presentation
• Use environments: ISO 3 (Class 1) – ISO 8 (Class 100,000) (final suitability depends on your process and cleaning method)
• Program requirements: Meets USP <797> and USP <800> wiper requirements; autoclave safe (dry wipers only; validate per site SOP)
• Temperature limit: Appropriate for use with temperatures less than 400°F (205°C)
• Country of origin: Made in the USA
• Shelf life: Sterile (dry) – 3 years from date of manufacture
• Traceability: Lot-coded for traceability and quality control

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as an engineered product, not a commodity consumable. For Vertex wipers, Texwipe describes a fully automated manufacturing approach with process monitoring intended to drive lot-to-lot consistency, while sealed-edge construction is used to minimize edge-driven particle release during demanding wipe steps.

Sterile Vertex formats such as TX3221 are gamma irradiated and supported by documentation practices (sterility validation, certificates/traceability) that help teams maintain audit readiness. SOSCleanroom (SOS) supports that manufacturing 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 wiping materials with predictable performance while maintaining procurement reliability.

• Two-ply, 100% continuous-filament polyester knit wiper
• Sealed edges to help minimize particle release from wiper edges (process-dependent)
• Designed for high sorption capacity for spill control, cleaning, and solution application
• Gamma irradiated sterile product; validated to a Sterility Assurance Level of 10⁻⁶
• Certificates of Processing/Compliance and lot traceability support documentation-driven programs
• Quarterly bacterial endotoxin testing (LAL) and additional contamination-control verification practices (per manufacturer materials)

• High sorption capacity: Two-ply construction is designed to reduce the number of wipers needed for spill control and wet wipe-downs (process-dependent)
• Edge-control in wet work: Sealed edges help limit fraying during folding and repeated strokes, reducing edge-driven releasables risk (process-dependent)
• Sterile confidence: Gamma irradiation and sterility validation support sterile workflows and controlled transfer expectations
• Solution handling performance: Built to absorb and release large volumes of cleaning and disinfecting solutions where controlled wetness matters
• Audit readiness: Lot coding and documentation support qualification and ongoing procurement reliability

• Wiping and cleaning surfaces, equipment, and parts
• Spill control and pickup of process fluids
• Applying and removing lubricants, adhesives, residues, and other solutions including disinfectants
• Cleaning with solvents such as isopropyl alcohol (IPA), ethanol, acetone, and degreasers (verify compatibility to your chemistry and SOP)
• Lining trays for holding, protecting, drying, and storing of parts, equipment, and devices
• Appropriate for use with temperatures less than 400°F (205°C)

• Fold for control: Fold into quarters to create multiple clean faces; rotate faces instead of re-wiping with a loaded surface.
• Wipe pattern: Use straight-line strokes (top-to-bottom or left-to-right) to avoid re-depositing contamination.
• Wet vs. dry: For solvent wipe-downs, dampen—do not over-saturate—so you maintain control and reduce dripping.
• Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins leaving residue/streaking.
• Sterile handling: Open and stage only what the step requires; keep unused wipes protected to avoid compromising sterile workflow controls.

• TX3221 vs. TX3042: Both are sterile Vertex sealed-edge wipers; choose TX3221 (11" x 11") when you want slightly more surface area per wipe for high-fluid tasks, and TX3042 (12" x 12") when maximum coverage per wipe is the priority.
• TX3221 vs. TX3049: Same Vertex sterile family; choose TX3221 for larger wipe face (11" x 11") and TX3049 for 9" x 9" handling in tighter work zones.
• Vertex vs. knit polyester (non-sterile): If sterile workflow, sealed-edge control, and high sorption are decision drivers, Vertex sterile is a common selection; for general non-sterile wipe-downs, a standard polyester knit wiper may be sufficient (process-dependent).
