Cellulose Acetate Membrane Paper

Cellulose acetate is the most widely used and tested material for natural gas sweetening as in uop s membrane systems 15 typical permeation data for cellulose acetate commercial membranes are.

Cellulose acetate membrane paper.

The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications. It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards in photographic film cellulose acetate replaced nitrate film in the 1950s being far. Cellulose acetate membrane circle oe 66 0 2 µm pore size 300 600 mm sheet 5 pcs 0 2 µm.

With high physical strength the membrane filters can be used up to 180ºc are suitable for hot gases and can be sterilized by all methods without sacrificing the integrity of the membrane. 2 and are available in the common pore sizes. Cellulose acetate membranes have a very low aqueous extract of. A pore size of 0 2μm is the filter of choice for sterile filtration and clarification of aqueous solutions ph 4 8 such as nutrient media buffers and sera.
