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.
