Cellulosic Membranes

By Whatman/GE Healthcare

Whatman offers cellulosic membranes in two formulations: (1) pure cellulose nitrate, and (2) mixed esters of cellulose nitrate and cellulose acetate.

Cellulose Nitrate (WCN) Membranes

Cellulose nitrate membranes are recommended for routine laboratory applications involving aqueous solutions. The membranes exhibit very narrow pore size distribution and have low levels of extractables. The membranes can withstand handling and autoclaving procedures without loss of integrity. Cellulose nitrate membranes are supplied as circles, sheets or reels. Plain or gridded white. Applications:

  • Sample preparation
  • Microbiological studies
  • Filtration of aqueous solutions
