Texwipe TX3252 Sterile AlphaSat with AlphaSorb HC 12" x 12" Polyester Wiper Pre-Wetted 70% IPA

TX3252 Sterile AlphaSat with AlphaSorb HC is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), high-capacity, two-ply polyester wiper pre-wetted with high-purity 70% isopropyl alcohol/30% deionized water that is 0.2µm filtered. Built for sterile and critical controlled environments, TX3252 combines strong knit performance with robust absorbency for wipe-downs, spill control, and solution application where teams want consistent wetting and reduced solvent-handling steps.

• Size: 12" x 12" (31 cm x 31 cm) nominal
• Material: 100% knitted continuous-filament polyester (two-ply)
• Construction: Two-ply, pinsonic construction (high-capacity wiping format)
• Edge: Cut edge
• Saturation: High-purity 70% IPA / 30% DI water, filtered through a 0.2µm filter
• Sterility: Gamma irradiated to 10-6 Sterility Assurance
• Packaging: 25 wipers/flatpack; 5 flatpacks/case (125 wipers/case)
• Use environments: ISO 4 (Class 10) through ISO 8 (Class 100,000) controlled environments (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. For sterile pre-wetted programs, that discipline extends beyond fabric and edge construction into controlled wetting chemistry, sterility validation (Sterility Assurance Level 10⁻⁶ per AAMI guidance), endotoxin testing, and documentation practices that support audit readiness and lot-to-lot consistency.

Texwipe also emphasizes verification through particles/ions/residue testing and describes process controls that 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 sterile-suite discipline.

• Saturated with high-purity 70% isopropyl alcohol/30% deionized water, filtered through a 0.2µm filter
• Unique two-ply, pinsonic wiper constructed from 100% knitted continuous-filament polyester
• Gamma irradiated to 10-6 Sterility Assurance
• Can be wiped down prior to introduction into the sterile suite
• Each shipment accompanied by a lot-specific Certificate of Irradiation and Certificate of Compliance with expiration date marked on each package
• Independent quality-control audits for sterility assurance

• Process simplification: Eliminates problems associated with filtration, sterilization, and mixing of alcohol and DI water
• Rigorous wiping with minimal shedding: Superior wiper strength supports demanding wipe-downs with minimal release of fibers and particles (process-dependent)
• Better solvent control: Optimizes solution usage and reduces over-spray of alcohol compared to spray-and-wipe steps
• Lower spill and waste risk: Reduces IPA spill potential and helps eliminate storage/disposal of excess solvents
• Less bottle maintenance: Eliminates the maintenance of squirt bottles

• Wiping down roller bottles and other production equipment in a sterile environment during and following production flow
• Cleaning environmental surfaces in sterile suites that require low solvent extractables and low particle generation
• Easy cleanup of soiled surfaces in sterile suites

• Open with sterile discipline: Stage flatpacks in the correct grade, open carefully to avoid glove contact with the next wiper, and close/dispose per your aseptic workflow.
• 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.
• Control solvent transfer: TX3252 is pre-wetted; avoid squeezing or “wringing” over critical zones to prevent dripping and solvent pooling.
• Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins leaving streaks/residue.

• TX3252 vs. TX1039: Both are 70% IPA pre-wetted options, but TX3252 is a larger 12" x 12" sterile, two-ply high-capacity format when coverage per wipe and absorbency are priorities.
• DI water vs. WFI programs: If your sterile suite standardizes on WFI-based wetting, consider sterile sealed-border alternatives like TX3280 (70% IPA / 30% WFI) where your SOP specifies WFI.
• Cut edge vs. sealed border: TX3252 is a cut-edge format; if your risk assessment prioritizes edge control, consider sealed-border sterile pre-wet options in the same program family.
