Fisherbrand Cotton Gauze Sponge 2 x 2 in. 12 Ply Case of 5000 Sponges

Fisherbrand™ Woven Cotton Gauze Sponges, 2 x 2 in., 12-Ply (22-362-178) – Case of 5,000

The Fisherbrand™ 22-362-178 is a laboratory-grade, highly absorbent woven cotton gauze sponge engineered for general fluid maintenance, surface prepping, small-scale component cleaning, and biological specimen tissue dressing. Fabricated from 100% natural, pure USP-grade cotton, these compact 2 x 2 inch square pads feature a thick 12-ply structural layering that maximizes capillary wicking and fluid retention relative to their size. Supplied as a high-volume facility logistics case of 5,000 sponges, these non-sterile swabs are manufactured with all raw cut edges folded completely inward to minimize lint fragmentation, filament shedding, or mechanical breakdown during intense scrubbing operations.

Technical Performance & Design

• Thick 12-Ply Woven Matrix: Engineered with 12 distinct layers of open-weave cotton fiber. This provides superior volumetric absorbency, rapid fluid pull, and compression cushioning compared to thin, lower-ply configurations.
• Folded Internal Edge Construction: Designed with all rough cut edges tucked neatly into the center of the sponge block. This prevents loose cotton filaments or frayed threads from unraveling and leaving structural debris behind on sensitive analytical equipment.
• 100% Pure Chemical-Free Cotton: Composed of high-grade, bleached virgin cotton fiber completely free of synthetic resins, starch additives, or optical brighteners that could leach out and cause assay carryover or skin sensitivities.
• High-Volume Stock Stability: Providing 5,000 individually portioned sponges allows procurement managers to stock clinical draw stations, animal research labs, and general benchtop workspaces efficiently, minimizing reorder frequency.

Key Benefits & Applications

• Small-Scale Surface Prepping: Ideal for dipping into disinfection solutions or cleaning alcohols to thoroughly scrub down small instruments, vial necks, glass cuvettes, and sensor electrodes.
• Animal Model Specimen Dressing: Provides excellent fluid absorption, blood clotting management, and structural packing capabilities across veterinary surgical platforms and animal research laboratories.
• Analytical Instrument Maintenance: Useful for applying lubricants, wiping away light oils, or scrubbing scale buildup off mechanical balance housings, microcentrifuge shafts, and metal tooling without scratching.
• **Facility Autoclave Custom Sterilization:** The pure cotton matrix allows facility managers to split the bulk non-sterile packs into smaller cleanroom bags and run standard steam autoclave processing loops to match specialized containment runs.

Fisherbrand™ is a registered commercial trademark of Thermo Fisher Scientific Inc. Part number 22-362-178 specifies the non-sterile 2x2 inch 12-ply woven cotton variant. For critical aseptic operations or human clinical diagnostic venipunctures requiring pre-sterilized unit doses, alternative single-pouch sterile gauze sponges must be substituted.
