TX49P Vertex 9" x 9" Polyester Laser Edge Cleanroom Wiper Pre-Wetted 70% IPA

TX49P Vertex is a pre-wetted, low-linting (no wiper is truly ‘zero-lint’ in every process condition) 100% continuous-filament polyester knit cleanroom wiper engineered for repeatable solvent wipe-downs in controlled environments. Each wiper is pre-wetted with 0.2 µm filtered, USP-grade 70% isopropyl alcohol (IPA) / 30% deionized water (DIW) to help deliver consistent wetness and VOC performance, and it uses a laser-sealed edge for tight fiber control during critical cleaning and spill response.

• Size: 9" x 9" (23 cm x 23 cm) nominal
• Material: 100% continuous-filament polyester knit
• Edge: Laser-sealed edge (sealed edge)
• Pre-wet solution: 0.2 µm filtered USP-grade 70% IPA / 30% DIW
• Packaging: 75 wipers/reclosable slider bag; 4 bags/case (300 wipers/case)
• Use environments: Commonly used in ISO Class 3–7/8 controlled environments (final suitability depends on your process, solvent controls, and wiping method)
• Country of origin: Made in the USA
• Shipping note: Hazardous shipment; ground shipping only (commercial address required per carrier/hazmat controls)

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—including hands-free manufacturing micro-environments—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.

• Unique polyester knit fabric structure designed for high sorption
• Laser-sealed edge for tight contamination control on wipe strokes
• Pre-wetted with 0.2 µm filtered USP-grade 70% IPA / 30% DIW for repeatable wetness and VOC levels
• Packaged in a reclosable slider bag to reduce evaporation and maintain consistent wipe wetness
• Quarterly microbial testing by Agarose Overlay and Limulus Amebocyte Lysate (LAL) endotoxin testing (manufacturer program)
• Individually lot coded for traceability and documentation alignment

• Consistent solvent delivery: Pre-wetting helps reduce operator-to-operator variability versus manual wetting (process-dependent)
• Soft feel for delicate work: Designed for use on sensitive surfaces and high-visibility components
• High sorption for spill control: Helps reduce the number of wipes required for pickup and wipe-down sequences
• Edge control: Laser-sealed edge supports cleaner wipe lines and reduces stray fiber contribution during strokes
• Contamination-control assurance: Manufacturer testing program supports confidence that the wiper is nonpyrogenic and free of cytotoxic leachables (as described by Texwipe)

• Wiping and cleaning surfaces, equipment exteriors, and parts in controlled environments
• Applying and removing residues and solutions including disinfectants (per facility compatibility and SOP)
• Solvent wipe-downs with IPA and other compatible chemistries (verify compatibility to your process)
• Spill response where absorbency and repeatable wetness matter
• Lining trays for holding, protecting, drying, and staging parts/devices

• Open/close discipline: Remove what you need, then reseal the slider bag immediately to reduce evaporation and keep wetness consistent.
• 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) and avoid circular scrubbing unless your SOP calls for it.
• Change-out triggers: Replace when the face becomes visibly soiled, streaking begins, or wetness drops below what your process requires.
• Flammability controls: Treat pre-wetted IPA wipes as flammable material—keep away from ignition sources and follow site EHS handling, storage, and disposal requirements.

• TX49P vs. TX49 (dry): Choose TX49P when repeatable solvent delivery matters; choose TX49 when your process requires dry wiping or controlled, site-managed wetting.
• TX49P vs. TX42P: Same Vertex pre-wetted concept, but TX42P (12" x 12") is typically selected when coverage per wipe matters on larger panels, doors, and equipment surfaces.
• Need sterile? If the workflow requires sterile presentation or sterile validation alignment, consider sterile pre-wetted Vertex options (for example, TX3049P) when available and appropriate.
