FREE-SAT 9" x 9" Polyester Presaturated Class 1-10 Wipers, 99% IPA / 1% DI Water

FREE-SAT 9" x 9" polyester presaturated wipes are a low-linting option (no wiper is truly ‘zero-lint’ in every process condition) for fast-dry wipe-downs, spill pickup, and surface prep in controlled environments. These wipes are pre-wetted with 99% isopropyl alcohol / 1% DI water and are laser cut from 100% virgin polyester with heat-sealed edges designed to minimize loose fibers and reduce handling variability compared with spray-and-wipe methods.

• Size: 9" x 9" (23 cm x 23 cm) nominal
• Saturation: 99% IPA / 1% DI water
• Material: 100% virgin polyester
• Construction: Interlocking knitted polyester
• Edge: Laser cut with heat-sealed edges (sealed-edge design)
• Sterility: Non-sterile
• Packaging: 30 wipes/tub; 12 tubs/case (flip-lid, re-sealable tub presentation)
• Use environments: Listed for Class 1-10 (ISO Class 3-4) use on SOSCleanroom; manufacturer literature also references typical use through ISO Class 5 depending on process and controls

FREE-SAT products are manufactured by High-Tech Conversions (a Hospeco Brands Group company), a long-established controlled-environment consumables producer with manufacturing operations supporting cleanroom, industrial, and electronics applications. Their approach emphasizes engineered materials, sealed-edge converting, clean processing, and packaging intended to protect wipe cleanliness through storage and dispensing.

For pre-wetted wipes, the practical differentiators are solvent consistency, edge integrity, and packaging discipline. SOSCleanroom supports customers standardizing pre-saturated wipe programs with reliable sourcing, responsive customer support, and inventory continuity for ongoing cleaning workflows.

• Pre-wetted with 99% IPA / 1% DI water for rapid drying and reduced rewetting variability
• Laser cut, heat-sealed edges designed to minimize loose fibers
• 100% virgin polyester with continuous fibers (engineered for very low particle/fiber contribution)
• Absorbent, abrasion-resistant knit suitable for rougher surfaces and fixtures
• Cleanroom processed and hermetically packaged (tub presentation for protected dispensing)
• Lot-to-lot traceability

• Fast evaporation: 99% IPA supports quick flash-off for wipe-down steps where dry-time matters (verify against your surface and residue limits)
• More repeatable wiping: Pre-saturated format helps standardize solvent load compared with manual spraying and guessing
• Reduced fiber risk at edges: Sealed-edge construction is selected to help limit edge shedding in ultra-critical areas
• Scrub-capable strength: Polyester knit resists tearing during equipment wipe-downs and tougher soil removal
• Convenient dispensing: Flip-lid tub format supports quick access while helping protect remaining wipes from exposure

• Surface wipe-down of benches, carts, tools, fixtures, and equipment exteriors
• Spill pickup of process fluids and solvent-compatible residues
• Fast-dry wipe-down steps for maintenance and changeovers
• Cleaning of stainless steel and hard surfaces where abrasion resistance helps
• General controlled-environment housekeeping and touch-point cleaning (process dependent)

• Keep the tub closed: Close the flip lid immediately after dispensing to help maintain saturation and reduce contamination exposure.
• One direction, one face: Use straight-line strokes; rotate to a fresh face instead of re-wiping with a loaded area.
• Don’t chase streaks with a wet wipe: If streaking occurs, follow with a clean dry wipe that is compatible with your SOP and surface finish.
• Change-out triggers: Discard when the wipe becomes visibly soiled, tacky, or begins to redeposit residue.
• Compatibility check: Verify IPA compatibility with plastics, coatings, adhesives, and sensitive finishes in your process.

• 99% IPA vs. 70% IPA: 99% IPA generally dries faster and can be preferred for rapid wipe-down steps; 70% IPA is often selected when longer wet contact time is desired (process-specific).
• Non-sterile vs. sterile: Choose sterile only when your area classification, aseptic practice, or validation requires it.
• Tub wipes vs. bagged wipes: Tub presentation supports quick dispensing and saturation retention; bagged wipes may be preferred for kitting or point-of-use staging in some workflows.
