1200159 W44 Cellulose Weighing Paper Sheet, Nitrogen Free, Non-Absorbing, High-Gloss, 4 x 4 Inches (Pack of 500)

LabExact W44 cellulose weighing paper is used to convey powders or gelatinous paste samples to and from balances and other laboratory equipment. The surface is highly calendered (non-treated gloss) to a smoothness which resists sample hold or moisture absorption. The high-gloss, milk-white paper is semi-opaque, non-absorbent, and nitrogen-free. It resists tearing during quadrant folding or enveloping, and increases abrasion durability during spatula scraping. Material chemistries are verified against a standard prior to the paper-making process, ensuring lot-to-lot reproducibility. Other applications for this paper include using as slip sheets between samples or slides or liners within containers, short-term exposure as a moisture barrier, or for laminating backing for structural support.
