Cellulose acetate membrane paper.

The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. Cellulose acetate is the acetate ester of cellulose it was first prepared in 1865. 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. Cellulose acetate ca membranes are made of entirely cellulose acetate polymer.

A 0 22 µm pore size non sterile filter validated for air monitoring. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications. Co 2 permeability of 9 barrer 1 barrer 7 6 10 18 m 3 stp m m 2 s 1 pa 1 and co 2 ch 4 separation factor of 20. 2 and are available in the common pore sizes.

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. 300 x 600 mm 11 81 x 23 62 in nonsterile. 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. The high solubility of co 2 and h 2 s in cellulose acetate.

Cellulose acetate membranes have a very low aqueous extract of. These membrane filters have the lowest protein binding of the filer types in question and typically have the greatest throughput when used with proteinaceous solutions. Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses.
