Cellulose acetate membrane paper.

A 0 22 µm pore size non sterile filter validated for air monitoring. Cellulose acetate membrane circle oe 66 sterile 0 2 µm pore size 47 mm sheet 100 pcs 0 2 µm. 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. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications.

Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses. The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. 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. Cellulose acetate is the acetate ester of cellulose it was first prepared in 1865.

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. Cellulose acetate ca membranes are made of entirely cellulose acetate polymer. 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. The high solubility of co 2 and h 2 s in cellulose acetate.

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. 300 x 600 mm 11 81 x 23 62 in nonsterile. Cellulose acetate membranes have a very low aqueous extract of.
