STX1034 Sterile AlphaSat 4" x 4" Polyester Cleanroom Wiper Pre-Wet 70% IPA

STX1034 Sterile AlphaSat is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), high-absorbency polyester knit wiper used for critical cleaning, spill control, and controlled solvent application in controlled environments. It is constructed from 100% continuous-filament polyester in a double-knit, no-run interlock pattern for durability on equipment, fixtures, and rougher surfaces. Each package is gamma irradiated to 10^-6 Sterility Assurance Level (SAL) and supplied in a pre-wetted 70% IPA format to improve operator-to-operator repeatability during routine wipe-down steps.

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 sealed-border options), controlled cleaning/laundering, and packaging aligned to cleanroom application tiers.

For sterile, pre-wetted programs, Texwipe also emphasizes sterility assurance controls and documentation discipline, including gamma irradiation, lot traceability, and packaging practices intended to preserve wetness and reduce handling-driven variability at point of use. 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.

• Gamma irradiated to 10^-6 Sterility Assurance Level (SAL), according to AAMI guidelines
• Lot-specific information on each shipment simplifies record keeping
• Certificate of Processing confirming radiation dosage
• Certification of Compliance
• Expiration date marked on each package
• 100% polyester fiber — continuous-filament, double-knit
• Cleanroom laundered and packaged
• Solvent-safe packaging
• Lot-to-lot traceability

• Low-linting performance: Designed to help reduce particle and fiber contribution during wipe-downs (process-dependent)
• Sterility assurance + documentation: Supports workflows that require sterile processing expectations, lot traceability, and package-level expiration dating
• Durability on surfaces: No-run interlock knit helps resist snagging and abrasion on rougher equipment and fixtures
• Absorbency for wet steps: Effective for spill pickup and controlled application/removal of solvents and cleaning agents
• Chemical resistance: Polyester knit construction is commonly used with IPA and many other cleanroom-compatible solvents/cleaners (verify compatibility to your chemistry and SOP)

• General wiping of benches, carts, tools, equipment exteriors, and fixtures
• Spill control and pickup of process fluids
• Cleaning and polishing stainless steel
• Applying and removing disinfectants, cleaners, and process solutions
• Protective covering for parts and product during staging, transfer, or temporary storage
• Small-area sterile wiping (tight wipe points, touchpoints, and spot cleaning where a 4" x 4" format reduces incidental contact)

• Open-and-use discipline: Open the bag only when ready to wipe; reclose promptly to reduce evaporation and maintain consistent wetness.
• Fold for control: Fold 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. drip: Pre-wetted does not mean dripping—maintain control and avoid over-wetting seams, joints, and electrical interfaces.
• Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or leaves streaks/residue.

• Sterile vs. non-sterile (TX1034): Choose STX1034 when sterile processing and sterile documentation are required by the workflow; choose TX1034 when sterile processing is not required.
• Format fit (4" x 4"): Use STX1034 for glove/fingertip wiping, small tools, tight fixtures, and spot cleaning; step up to 6" x 6" or 9" x 9" when coverage per wipe matters.
• Ground shipping requirement: Because this is a pre-wetted, regulated shipment (ORM-D), plan for UPS Ground and U.S.-only destination restrictions in your replenishment cadence.
