Product Specification Sheet
Absorbent Cotton Roll — 1 lb, USP Purified
SKU RVX-ACR-1LB · Category: Cotton Balls & Rolls · Available to quote · Made to order
The US-standard 1 lb (454 g) absorbent cotton roll, 12" × 56", meeting the complete USP Purified Cotton monograph — all seven tests, including 24× absorbency capacity, fatty matter, ash, and pH limits. Most catalog cotton stops at an unverifiable "medical grade" label; USP purification also strips the short fibers that cause lint. Specified at the true US 454 g weight, not the 500 g metric roll.
