Cellulose Acetate Membrane Paper

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 membrane circle oe 66 0 2 µm pore size 300 600 mm sheet 5 pcs 0 2 µm. 2 and are available in the common pore sizes. Cellulose acetate membrane circle oe 66 sterile 0 2 µm pore size 47 mm sheet 100 pcs 0 2 µm. Cellulose acetate ca membranes are made of entirely cellulose acetate polymer.

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. 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. A 0 22 µm pore size non sterile filter validated for air monitoring. 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.

They are also used in applications where maximum protein recovery is critical. 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. Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses.

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.
