TX3280 Sterile AlphaSat10 12" x 12" Polyester Wiper Pre-Wetted 70% IPA / 30% WFI

TX3280 Sterile AlphaSat10 is a low-linting (no wiper is truly ‘zero-lint’ in every process condition) sterile, sealed-border polyester wiper pre-wetted with 0.2 µm filtered 70% USP isopropyl alcohol (IPA) / 30% Water for Injection (WFI). Built on SterileWipe™ LP 10 (100% continuous-filament polyester knit with thermally sealed borders), TX3280 is packaged in a resealable flatpack format designed for controlled wipe-downs in critical sterile environments where solution quality, traceability, and consistency matter.

• Size: 12" x 12" (31 cm x 31 cm) nominal
• Wiper material: 100% continuous-filament polyester knit
• Edge/border: Thermally sealed border (sealed-border construction)
• Sterility: Triple-bagged and gamma irradiated to SAL 10-6 (ANSI/AAMI/ISO 11137)
• Pre-wet solution: 70% IPA / 30% WFI by volume, 0.2 µm filtered
• Solution quality notes: IPA meets USP requirements; WFI meets USP requirements; endotoxin levels <0.25 EU/mL; certificates of analysis provided with every lot
• Packaging: 50 wipers/flatpack; 5 flatpacks/case (250 wipers/case); triple-bagged presentation
• Use environments: Designed for critical sterile environments in pharmaceutical aseptic processing areas, biotechnology manufacturing, microbiological laboratories, sterile suites, and prep rooms (final suitability depends on your process and cleaning method)

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as an engineered product, not a commodity consumable. Its manufacturing approach starts with fabric and yarn selection (often continuous-filament polyester for lower shedding), then controls edge construction (cut-edge, sealed-edge, and patented sealed-border options), controlled cleaning/laundering, and packaging aligned to cleanroom application tiers.

Texwipe also emphasizes verification through fibers/particles/ions/residue/endotoxin testing and describes automation-forward processes—such as Vectra® continuous cleaning with 100% machine-vision inspection and hands-free sterile manufacturing steps—to improve lot-to-lot consistency and reduce handling-driven contamination risk. 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 wiping materials with predictable performance while maintaining procurement reliability and audit readiness.

• Lot-specific information on each case simplifies record keeping
• Certificate of Processing confirms radiation dosage
• Certificate of Compliance
• Certificate of Analysis
• Expiration date marked on each package
• Pre-wetted with 0.2 µm filtered 70% IPA / 30% WFI by volume
• Cleanroom-laundered 100% polyester knit with thermally sealed borders
• Triple-bagged for easy entry into sterile environments
• Independent quality control audits for sterility assurance

• Reduces in-house solution handling: Eliminates blending, filtration, processing, and QC expense of in-house production of IPA solutions.
• More controlled solvent use: Optimizes solution usage and helps reduce overspray of alcohol versus spray-and-wipe practices.
• Lower spill and disposal burden: Reduces IPA spill potential and helps eliminate storage/disposal of excess solvents.
• Rigorous wiping with low release: Superior wiper strength supports rigorous wiping with minimal release of fibers and particles (process-dependent).
• Smoother wiping action: Wiper glides smoothly over surfaces for controlled wipe-downs.
• Fiber control for sterile zones: Extremely low levels of releasable visible fibers consistent with requirements for sterile ISO Class 4 (Class 10) and higher environments.
• Transfer-friendly packaging: Packaging permits alcohol wipe-down of the exterior bag before introduction of the inner bag to sterile suites.
• Audit-ready traceability: Assures quality of individual lots and lot-to-lot traceability with supporting documentation.

• Developed to clean sterile environments without compromising the sterile nature of those environments
• Cleaning production equipment and environmental surfaces in a sterile environment during and following the production flow
• Ideal for wiping gloved hands

• Control transfer into the suite: Wipe down the exterior bag per your facility practice before staging the inner bag in the sterile area.
• Open/dispense with discipline: Open the resealable flatpack only as far as needed; reclose promptly to help maintain consistent wetness.
• Wipe pattern: Use straight-line strokes (top-to-bottom or left-to-right) and avoid back-and-forth scrubbing that can re-deposit contamination.
• Face management: Fold to present clean faces; rotate faces instead of re-wiping with a loaded surface.
• Avoid pooling: Keep wipe-downs controlled; do not flood surfaces with excess solvent. Use additional wipers rather than overworking one.
• Glove wiping: If used for gloved hands, follow your gowning/aseptic workflow and discard after the step to prevent cross-contact.

• TX3280 vs. TX3285: Both are sterile AlphaSat10 with sealed-border polyester wipers, but TX3280 is 12" x 12" and uses 70% IPA / 30% WFI in flatpacks. TX3285 is the 9" x 9" format typically packaged as smaller packs for tighter staging and smaller wipe areas.
• WFI-driven programs: Choose TX3280 when your SOPs call for WFI-based wetting (or when investigational rigor and solution pedigree are emphasized). For non-WFI programs, other sterile pre-wetted options may be appropriate.
• Need higher sorption in a pre-wet: If you want more capacity per wipe while staying in a sterile pre-wetted workflow, consider AlphaSat options built on higher-sorption substrates (where compatible with your residue/particle targets).
• Ethanol vs. IPA: If IPA is not preferred for a surface or process step, sterile ethanol pre-wetted sealed-edge alternatives may fit better (validate against your material compatibility and residue expectations).
