Nitrogen-Free Cellulose Weighing Paper, 3x3 inch, Analytical Grade, High-Gloss, 500/Pack SKU: LE-W33

Featuring analytical purity-grade cellulose technology designed for conveying powder or gelatinous paste samples to and from balances and instruments. Highly-calendered surface (non-treated gloss) delivers smoothness that resists sample hold or moisture absorption while maintaining nitrogen-free composition. Ultra-pure cellulose construction with exceptional structural integrity maximizes analytical accuracy and sample recovery performance in critical laboratory weighing applications.

Key Cellulose Membrane Characteristics

High-gloss, milk-white cellulose paper maintains semi-opaque, non-absorbent, and nitrogen-free properties
Highly calendered (non-treated gloss) surface texture resists sample hold and moisture absorption during transfer operations
Smoothness characteristics prevent sample retention while optimizing spatula scraping and material recovery
Nitrogen-free formulation ensures very smooth surface performance and superior sample recovery capabilities
Material chemistries verified against standards prior to paper-making process ensuring exceptional lot-to-lot reproducibility

Key Construction Characteristics

Sufficient structural integrity resists tearing during quadrant folding, enveloping, and increases abrasion durability during spatula scraping
3 x 3 inch (76 x 76 mm) square format optimized for analytical balance platforms and standard laboratory weighing protocols
Lightweight construction maintains strength to support analytical size samples and high-density materials
Smooth medium gloss surface delivers clean, dust-free sheets ideal for transferring weighed materials
Shiny pergamyne paper composition allows visual determination that all sample material has been completely removed

LE-W33 paper achieves exceptional sample transfer efficiency while maintaining chemical purity standards required for quantitative analytical procedures. Transfer capability allows samples to be moved to scales without adding unwanted substances that could impact analytical results. Versatile application performance extends to slip sheets between samples or slides, short-term moisture barriers, container liners, and laminating backing for structural support, delivering comprehensive laboratory utility in your most demanding analytical weighing and sample preparation workflows.
