Fisherbrand Cotton Gauze Sponge 4 x 4 in. 12 Ply Case of 2000 Sponges

Fisherbrand™ Woven Cotton Gauze Sponges, 4 x 4 in., 12-Ply (13-761-52) – Case of 2,000

The Fisherbrand™ 13-761-52 is a highly absorbent, laboratory-grade woven cotton gauze sponge engineered for general fluid uptake, surface prepping, instrument cleaning, and wound packing applications. Fabricated from 100% natural pure USP-grade cotton, these heavy-duty 4 x 4 inch square pads feature a thick 12-ply structural layering that maximizes fluid retention and provides structural loft. Supplied as a high-volume facility logistics case of 2,000 sponges, these non-sterile swabs are manufactured with all raw cut edges folded completely inward to minimize lint fragmentation, thread 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, capillary fluid pull, and compression cushioning compared to standard 8-ply alternatives.
• 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 laboratory components.
• 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.
• Fluffy and Soft Surface Ergonomics: Delivers high mechanical cushioning and structural loft, allowing the sponge to conform smoothly around intricate instrument shapes, animal tissue structures, or rough machinery brackets.

Key Benefits & Applications

• General Laboratory Surface Prepping: Ideal for dipping into disinfection solutions or cleaning alcohols to thoroughly scrub down extraction benches, spill reservoirs, and biological safety cabinets.
• High-Capacity Animal Model Specimen Dressing: Provides excellent fluid absorption, blood clotting management, and structural packing capabilities across veterinary surgical platforms and animal research laboratories.
• Industrial Equipment and Hardware Wiping: Useful for applying lubricants, wiping away heavy oils, or scrubbing scale buildup off mechanical balance housings, centrifuge shafts, and metal tooling.
• 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.
