TX42P Vertex 12" x 12" Polyester Laser Edge Cleanroom Wiper Pre-Wetted 70% IPA

TX42P Vertex is a low-linting (no wiper is truly ‘zero-lint’ in every process condition) pre-wetted, high-sorption cleanroom wiper designed for repeatable solvent wipe-downs on larger surfaces. It uses a 100% continuous-filament polyester knit with a laser-style sealed edge, then pairs that substrate with a controlled pre-wet solution—0.2 µm filtered, USP-grade 70% IPA / 30% DI water—to help stabilize wetness, reduce operator variability, and minimize edge-driven shedding during critical cleaning, spill pickup, and solution application.

• Size: 12" x 12" (30 cm x 30 cm) nominal
• Material: 100% continuous-filament polyester knit
• Construction: High-sorption knit structure (Vertex platform)
• Edge: Laser-style sealed edge (sealed edge control for reduced fray)
• Chemistry (pre-wetted): 0.2 µm filtered, USP-grade 70% IPA / 30% DI water
• Packaging: 50 wipers/recloseable bag; 4 bags/case (200 total/case)
• Cleanroom environment fit: Commonly used from ISO 3 (Class 1) through ISO 8 (Class 100,000) depending on process and cleaning method
• Country of origin: Made in the USA
• Shipping note: Ground-only hazardous shipment; $35 Hazmat fee per case/package may apply (per checkout requirements)

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as a controlled system—substrate + edge control + cleaning/packaging discipline—not a commodity consumable. Vertex wipers are positioned as processed on a fully automated, hands-free manufacturing platform intended to reduce human-contact contamination variables while improving lot-to-lot consistency in critical cleaning applications.

Texwipe also emphasizes verification signals that matter in audit-facing programs, including low ions/NVR/particles/fibers positioning, individual lot coding for traceability, and additional assurance testing (including quarterly cytotoxicity and endotoxin testing as described in Vertex materials). SOSCleanroom (SOS) supports that discipline with a close working relationship focused on continuity of supply, clean documentation handoff (certs and lot traceability), and practical application support—so customers can standardize pre-wetted wiping with predictable solvent delivery while maintaining procurement reliability and inspection readiness.

• 100% continuous-filament polyester knit substrate
• Laser-style sealed edge for edge control and reduced fray risk
• Pre-wetted with 0.2 µm filtered, USP-grade 70% IPA / 30% DI water
• Recloseable slider bags to reduce evaporation and preserve consistent wetness

• Repeatable solvent delivery: Controlled pre-wet chemistry helps reduce operator-driven wetness drift, over-application, and streaking variability.
• Edge-driven shedding control: Sealed-edge construction is designed to reduce edge fray, which is often where knit wipes fail first in defect-sensitive workflows.
• High sorption for wet work: Built for spill pickup, wipe-downs, and solution application/removal where liquid capacity and stability matter.
• Reduced evaporation drift at point-of-use: Slider-bag packaging helps keep “first wipe vs. last wipe” behavior more consistent during a shift.

• Wiping and cleaning surfaces, equipment exteriors, and parts handling/staging areas
• Applying and removing lubricants, adhesives, residues, and other solutions (including disinfectants) per SOP
• Solvent cleaning with common chemistries such as IPA, ethanol, acetone, and degreasers (verify compatibility to your process)
• Spill control and pickup of process fluids where sorption capacity matters
• Lining trays for holding, protecting, drying, and storing parts, equipment, and devices

• 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 to avoid re-depositing contamination; avoid “scrubbing circles” unless your SOP specifically calls for it.
• Wetness control: TX42P is designed to be “ready to wipe.” Do not re-wet in-bag; if more solvent is required, follow your validated add-solvent method and VOC controls.
• Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins to leave streaks/residue.
• Bag discipline: Open/close the slider bag promptly and keep it closed between pulls to reduce evaporation drift; stage only what you will use in the task window.

• TX42P vs. TX49P: Same Vertex pre-wetted platform and chemistry, but TX42P is 12" x 12" for larger surface coverage per wipe; TX49P is 9" x 9" when tighter work zones or smaller folds are preferred.
• Non-sterile vs. sterile pre-wetted: Choose TX3042P when sterile presentation/sterility assurance documentation is required; choose TX42P for non-sterile controlled environments where sterile is not mandated.
• Pre-wetted vs. dry Vertex (TX42 / TX49): Use pre-wetted when you want standardized solvent load and reduced spray handling; use dry when your SOP calls for custom wetting, autoclave (dry-only), or alternative chemistries.
