ULTIMATE 5 ESD Cleanroom 12" x 12" Wiper (ISO Class 3-4)

ULTIMATE 5 ESD is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), ESD / antistatic sealed-edge wipe designed for ultra-critical controlled environments where electrostatic discharge control and contamination control must work together. It is described as extremely low in particle generation and extremely low in chemical extractables, using premium-quality virgin polyester fibers and carbon-core nylon fibers continuously filamented throughout a no-run knit construction for durability and controlled wipe performance.

• Size: 12" x 12" nominal
• Material: Virgin polyester fibers with carbon-core nylon fibers continuously filamented throughout the knit (ESD / antistatic construction)
• Construction: No-run knit (manufacturer description)
• Edge: Laser cut, sealed edges (sealed-edge perimeter)
• Cleanroom compatibility: ISO Class 3 & 4 (Class 1 & 10)
• Packaging: Double bagged; hermetically sealed cleanroom packaging
• Quantity options: 100 wipers per bag; 10 bags of 100 wipers per case (1,000 wipers/case)
• SOSCleanroom SKU: ULT5-1212 BAG

High-Tech Conversions is described on SOSCleanroom as a leading global manufacturer founded in 1995, with facilities in the USA, China, Germany, and Mexico. For ULTIMATE 5 ESD, manufacturer-provided copy emphasizes engineered ESD/antistatic knit construction, sealed-edge converting, and disciplined cleanroom laundering and packaging intended to reduce handling-driven contamination and improve lot-to-lot consistency.

As described on the SOSCleanroom listing, the fabric undergoes special processes that include cleaning, scouring, laser cutting, and a proprietary cleaning process. It is described as laundered in a Class 100 cleanroom using ultra-filtered water of 0.45 micron purity and HEPA-filtered air during moisture removal, then hermetically sealed in cleanroom-cleaned packaging under Class 10 air-stream. The wipes are also described as individually inspected with lot-to-lot traceability using ISO 9000 standards. SOSCleanroom supports ESD and contamination-control programs with responsive service, continuity of supply, and practical product-selection guidance.

• ESD / antistatic knit construction (carbon-core nylon fibers continuously filamented throughout)
• Sealed edges created by laser cutting (per manufacturer description)
• ISO Class 3 & 4 (Class 1 & 10) cleanroom compatibility
• Cleanroom laundering and hermetic packaging (manufacturer description)
• Individually inspected; lot-to-lot traceability (ISO 9000 referenced by manufacturer description)

• ESD-safe wiping support: Antistatic construction is intended to help reduce electrostatic risk when wiping static-sensitive electronics and equipment (program-dependent).
• Sealed-edge confidence: Laser-sealed edges are intended to eliminate loose fibers at the perimeter during critical wipe-downs.
• Low extractables focus: Manufacturer copy emphasizes extremely low particle generation and chemical extractables for ultra-critical processes.
• Audit-friendly handling: Lot traceability and cleanroom packaging discipline support tighter staging and documentation expectations in controlled environments.

• Wiping printed circuit boards (PCBs) and static-sensitive electronics
• Cleaning anti-static electronics and equipment surfaces in ESD-controlled zones
• Bench, cart, tool, and fixture wipe-downs in ultra-critical controlled environments (process-dependent)
• Surface prep steps where sealed edges and low extractables are selection drivers

• 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) to reduce re-deposition risk.
• ESD discipline: Use within your ESD control plan (grounding, ionization where applicable, approved chemistries) and avoid uncontrolled rubbing that can increase charge generation.
• Bag handling: Stage only what you need; re-seal inner bags promptly to reduce exposure and handling-driven contamination.
• Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins leaving streaks/residue.

• 12" x 12" vs. 9" x 9": Same ULTIMATE 5 ESD family and ISO Class 3–4 intent; the 12" x 12" format is typically chosen when more coverage per wipe reduces change-outs on larger benches and tool sets.
• Ultimate 5 ESD vs. economy ESD wipes: If your process allows higher ISO classes, economy ESD wipes may be sufficient—but may not match the same sealed-edge and ultra-critical positioning.
• ESD vs. non-ESD ultra-critical wipes: If ESD is not a program requirement, ultra-critical non-ESD sealed-edge polyester wipes can be viable alternatives (select based on your SOP, surface sensitivity, and validation needs).
