Kimtech 34256 Science Kimwipes are designed for delicate, light-duty wiping where the goal is clean handling, controlled usage, and reduced rework—especially around optics, labware, and sensitive electronics. SOSCleanroom customers typically choose this format when they want a predictable, one-at-a-time wipe from a pop-up box, with a low-linting tissue that behaves gently on smooth surfaces.

Important context for critical environments: this is a lab-grade tissue wipe with “low extractables” positioning, but it is not presented as a cleanroom-validated synthetic wiper with published ionic/NVR tables. If your process requires audit-grade extractables documentation, batch-to-batch cleanliness limits, or ISO-class cleaning validation, treat Kimwipes as a convenience wipe and validate suitability in your own quality system before adopting it into regulated steps.

While the Technical Vault “swab” template is locked, Kimtech 34256 functions as a delicate-task wiper for:

• Optics and lens-adjacent cleaning where a gentle wipe is preferred (verify your lens coating compatibility first).
• Laboratory instruments, slides, and general bench-top wipe-down of noncritical surfaces.
• Light spill pickup and dust/particle pickup in lab and electronics areas using controlled, one-at-a-time dispensing.
• General delicate wiping where portability and consumption control matter (pop-up box at point of use).

• One-at-a-time dispensing helps reduce waste and discourages bare-hand “fishing” in the box.
• Low-linting tissue + low extractables positioning for delicate wiping tasks (validate for your limits).
• Gentle wipe feel intended for delicate surfaces when used wet (reduce dry-swipe abrasion risk).
• Standardized case configuration supports predictable re-ordering and stocking (see put-up in specifications).
• Portable pop-up format fits benches, carts, and instrument stations without additional dispensers.

Kimtech 34256 is described as a 1-ply tissue wipe in a pop-up dispensing box. Manufacturer materials emphasize low-linting and low extractables positioning for lab and delicate wiping tasks. The dispensing system is designed to reduce lint release and electrostatic buildup during dispensing, supporting use around sensitive work areas.

These are SKU-level identifiers and logistics details that matter when you are standardizing bench stations, stocking cabinets, or writing materials lists. If your internal documents use metric, the manufacturer lists the sheet size as 42.1 cm x 37.3 cm (equivalent class to 16.6" x 14.7").

Many cleanroom-grade wipers publish typical ionic extractables and typical nonvolatile residue (NVR) to support contamination budgets. For Kimtech 34256, the manufacturer positions the wipe as low-linting and low extractables for delicate tasks, but typical ionic/NVR tables are not published in the source basis. If you are applying this wipe in a controlled process, treat the tables below as “not stated” and use your internal extraction method/acceptance criteria.

• Packaging configuration: 140 sheets per box; 15 boxes per case; 2,100 sheets per case.
• Dispensing control: pop-up box; one-at-a-time dispensing to reduce waste and reduce “box rummaging.”
• Traceability identifiers (examples from manufacturer listing): Product code 34256; GTIN 10036000342564; material number 10028743; short code 34256B.
• Sterility: not stated in source basis (no terminal sterilization claim located for this SKU). If sterility is required, use a sterile-qualified wipe and confirm packaging integrity requirements in your SOP.
• Country of origin (manufacturer statement): Thailand.

Kimtech 34256 performs best when you treat it as a controlled, delicate wipe—minimizing friction, minimizing re-contact, and controlling solvent load. For delicate surfaces, “wet-wipe first” is often safer than aggressive dry wiping.

• Gloves on, clean hands: handle the wipe by edges; avoid touching the wipe face that will contact the surface.
• Control your wipe geometry: fold into a flat pad (not a crumpled ball) to reduce snagging and to keep pressure uniform.
• Wet vs. dry: if compatible, lightly wet the wipe (do not soak) to reduce friction and help capture fine residues; confirm solvent/material compatibility first.
• One direction, single pass: wipe in one direction, then refold to a fresh face; do not “scrub back and forth” if residue control matters.
• Edge discipline: on optics and polished parts, keep the fold edge off the critical zone; use the smoothest face of the folded wipe.
• End-of-use control: discard after visible loading, after rough contact, or after a solvent wipe—reusing a tissue wipe is a common contamination reintroduction pathway.

• Fiber transfer on rough edges: tissue wipes can snag on burrs, threads, or sharp corners; deburr the surface or switch wipe type for that step.
• Dry-wipe micro-scratching risk: wiping dry on delicate coatings can increase abrasion potential—use a compatible wet wipe technique where appropriate.
• Over-wetting: excessive solvent load can cause streaking, residue redistribution, or long dry times; apply solvent control, not saturation.
• Re-contact contamination: refolding onto a used face or reusing a wipe spreads residue; treat each face as “one pass” for critical areas.
• Process mismatch: using a lab wipe where a validated cleanroom wipe is required can create documentation gaps (extractables/NVR) during audits.

If you are staying within the Kimtech Science Kimwipes family and want to adjust durability, thickness, or sheet format, these closely adjacent options are commonly evaluated:

• Kimtech 34721 (2-ply Science Kimwipes, 14.7" x 16.6"): similar footprint; heavier wipe feel (SOSCleanroom related product listing).
• Kimtech 34155 (1-ply, smaller sheet format with higher box/case counts): suited to high-consumption bench stations where smaller sheets reduce waste (manufacturer “other products to consider”).
• Leading private label delicate-task wipes: typically compete on price, but can vary in fiber blend and softness; validate linting and residue behavior before substitution.

Kimtech 34256 fits best as a bench-ready, delicate-task wipe in laboratories, electronics work areas, and non-sterile support zones where controlled dispensing and low-linting behavior are valued. It is also practical for instrument wipe-downs, lens-adjacent tasks, and general precision wiping where you want to reduce wipe overuse and keep a consistent format at point-of-use.

For higher-stringency cleanroom steps (published ionic/NVR limits, validated cleaning protocols, or documentation packages), SOSCleanroom customers often standardize cleanroom-grade wiping systems that come with stronger lot-to-lot documentation discipline. SOSCleanroom’s long-standing relationship with ITW Texwipe supports that “audit-ready” path when your program requires it—continuity of supply, consistent product identity, and the documentation ecosystem that quality teams typically ask for.
