Texwipe STX1709P REVOLVE (Sterile, 70/30 IPA): Repeatable Wetness, Sealed-Edge Control, and Sustainable Polyester for ISO-Driven Cleaning
Last reviewed: Jan. 4, 2026 | Audience: contamination control, cleanroom operations, EHS, quality
Texwipe STX1709P REVOLVE is a sterile, pre-wetted (70% IPA / 30% DI water) sealed-edge polyester cleanroom wiper designed for situations where solvent control and contamination discipline must be consistent shift-to-shift. Its practical value is not only in “having alcohol on the wipe,” but in removing operator-to-operator variability that shows up as streaking, residue carryover, inconsistent dwell time, and overuse of bottles/spray.
REVOLVE also addresses a real-world constraint many teams face: raising sustainability performance without lowering cleanliness expectations. The wiper is made from 100% upcycled polyester (rPET) and processed for low ions, low NVR, low particles, and low fibers—so you can pursue waste-reduction goals without rewriting your entire cleaning validation logic.
What it’s for
Controlled cleaning and wipe-down of surfaces, tools, carts, benches, transfer points, and equipment exteriors where a sterile, pre-wetted IPA wipe supports consistent solvent application, repeatable evaporation behavior, and predictable contamination outcomes—especially in ISO-driven environments, aseptic processing support areas, and USP <797>/<800> workflows.
Decision drivers
If you are standardizing cleaning outcomes (not just “cleaning effort”), these are the drivers that typically separate a dependable pre-wetted sterile wiper from a recurring deviation generator.
- Repeatable wetness and solvent control: Pre-wetted with 0.2 µm-filtered, USP-grade 70% IPA / 30% DI water to reduce spray-bottle variability, VOC spikes, and uneven dwell time across operators.
- Edge strategy for fiber/particle discipline: Sealed-edge construction is selected when edge fray, snagging, and fiber release are unacceptable failure modes.
- Sterility assurance for critical workflows: Gamma irradiated to a 10−6 SAL and packaged to protect the sterile presentation through handling and staging.
- Contamination profile you can defend: Typical data includes particles/fibers, NVR, and ionic extractables—useful when investigations shift from “what did we do?” to “what did the material contribute?”
- Sustainability with continuity: Upcycled polyester (rPET) supports sustainability goals while maintaining comparable performance characteristics to virgin polyester-based wipers, per manufacturer documentation.
Materials and construction
STX1709P is made from 100% upcycled polyester (rPET) and finished with a sealed edge. Polyester’s core advantage in contamination control is that continuous-filament synthetics can be processed to reduce loose fiber contribution versus many blended or pulp-based substrates—while still providing the abrasion resistance and “wipe feel” operators need for controlled wipe-down.
The “pre-wetted” format matters operationally: instead of asking each operator to create a solvent film with a bottle (and guessing at the volume), each wipe delivers a consistent starting wetness profile. That consistency is often what improves cleaning repeatability, because it stabilizes the solvent’s ability to solubilize residues and carry contamination into the wiper matrix rather than redistributing it.
Specifications in context
Format: Sterile, pre-wetted wiper (70% IPA / 30% DI water). Size: 9" x 9" (23 cm x 23 cm). Material: polyester (upcycled rPET). Edge: sealed edge. Packaging: 50 wipers per bag; SOSCleanroom case pack is 4 bags per case (200 total). Sterile packaging is triple-bagged with a case liner (fourth protective layer) and uses recloseable slider bags to reduce evaporation. Shelf life: sterile (dry and pre-wetted) products are listed at 3 years from date of manufacture. Cleanroom use range: manufacturer positions REVOLVE for ISO Class 3–7 environments; SOSCleanroom lists an ISO 4 (Class 10) through ISO 8 (Class 100,000) range—treat ranges as application guidance and align to your SOP and risk tolerance.
Cleanliness and performance metrics
Use metrics as “typical starting points,” then validate against your residues, surfaces, and process risk. For investigation work, the most practical lens is: particles/fibers (re-deposition risk), NVR (film/residue risk), and ions (corrosion/ionic contamination risk).
Typical contamination and performance data (manufacturer technical data sheet): LPC (≥0.5 µm) ~5.5 × 106 particles/m2; fibers (>100 µm) ~300 fibers/m2. NVR: IPA extractant ~0.05 g/m2; DI water extractant ~0.01 g/m2. Ions (typical): sodium ~0.08 ppm; potassium ~0.03 ppm; chloride ~0.04 ppm. Sorptive capacity ~450 mL/m2; sorptive rate ~0.3 second; basis weight ~125 g/m2. Test methods cited include IEST-RP-CC004.3 and ASTM E2090-12, and the manufacturer notes data are typical analyses (not specifications).
Packaging, sterility, and traceability controls
In practice, most sterile wipe failures are not “bad wipes”—they are handling failures: opened too early, staged improperly, reclosed poorly, or moved between pressure regimes without a clean presentation. STX1709P’s triple-bag sterile configuration with case liner is built for controlled introduction, and the recloseable slider bag is a direct control for evaporation-driven variability (dry wipes, streaks, and repeat cleaning cycles). The product is gamma irradiated to a 10−6 SAL per AAMI guidance, and documentation pathways (Certificates of Compliance/Analysis/Irradiation) support audit-grade traceability expectations.
Rule of thumb: Treat the slider bag like a controlled container: open only long enough to remove what you need, then reclose immediately. If the wipe “feels” different between the first and last wipe in a bag, your evaporation control is failing—and your cleaning results will drift with it.
Best-practice use
The goal is to remove and capture contamination—not redistribute it. Standardize technique the same way you standardize materials.
- Fold for clean faces: Fold into a manageable pad and rotate to a fresh face frequently; do not “chase” residues with a loaded wipe.
- One-direction passes with overlap: Wipe in one direction using controlled pressure, overlapping each pass; avoid scrubbing circles that re-deposit loosened contamination.
- Control the boundary between zones: For sterile workflows, stage outer bags outside the critical zone, then present the innermost sterile bag at point-of-use to reduce handling risk.
- Respect IPA behavior: IPA flashes quickly; allow appropriate dwell time for solubilization, and avoid wiping hot surfaces where evaporation outpaces cleaning.
- Use the right “end state” check: If you are wiping for visual cleanliness, validate under the lighting that reveals streaks; if wiping for residue/ions, align wipe technique to the assay method (swab/rinse) so results are comparable.
Common failure modes
Evaporation drift: Leaving the slider bag open changes wetness and creates streaking/variable cleaning. Cross-contamination: Using the same wipe face across multiple surfaces transfers residues rather than removing them. Over-aggressive mechanical action: Excess pressure or repeated scrubbing can increase surface damage risk and drive redeposition. Temperature mismatch: Applying IPA wipes to elevated-temperature surfaces can cause rapid flash-off and reduced cleaning effectiveness. Zone-control breakdown: Opening sterile bags too early or staging them incorrectly can undermine sterile intent even if the wipe itself is sterile.
Closest competitors
Berkshire Sterile SatPax® MicroSeal® – VP (70% USP IPA): An ultrasonically sealed-edge, continuous-filament polyester knit wiper pre-wetted with 70% USP-grade IPA and gamma irradiated to a 10−6 SAL. Mechanistically, this is the closest “like-for-like” competitor (sealed-edge polyester knit, sterile, IPA-saturated). If your decision is primarily edge control + sterile presentation, this class competes directly; REVOLVE differentiates by using 100% upcycled polyester and emphasizing repeatable wetness controls in the packaging and documentation set.
Contec PROSAT® Sterile wipes (70% USP IPA / 30% DI water): A presaturated sterile wipe typically made from hydroentangled nonwoven cellulose/polyester blends. Mechanistically, this targets general surface cleaning and transfer disinfection with a softer nonwoven hand; the tradeoffs are different absorbency/drag behavior and a different shedding profile versus sealed-edge polyester knit formats. Teams often choose nonwovens for broad-area wipe-down where “wipe feel” and coverage matter most, and sealed-edge knits where fiber and edge-related risks dominate.
Where it fits in a cleanroom wiping program
STX1709P is a strong “standard work” wiper for sterile, solvent-based wipe-down steps where you want consistent wetness without relying on bottles, and where sealed-edge control helps reduce edge-related fiber/particle contributions. It commonly sits between two extremes: (1) spray-and-wipe approaches that introduce variability and overspray, and (2) higher-friction specialty wipes used for aggressive residue removal. For many programs, it becomes a default for benches, carts, equipment exteriors, transfer points, and production support surfaces—especially when USP <797>/<800> expectations or ISO-driven environmental requirements are in play.
Terminology note: Engineered for low-linting performance; no wiper is truly “lint-free” in every process condition.
