Cellulose Acetate Membrane Filter Paper

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 membrane filter paper.

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. Here we explore different filtration properties and how to take a preventative rather than reactive approach minimizing time spent troubleshooting and maximizing efficiency. Filtration is an integral piece of nearly every workflow of every lab.

Cellulose acetate ca membranes are made of entirely cellulose acetate polymer. The membrane filters are available in different pore sizes and three different material types. Biologically inert mixtures of cellulose acetate and cellulose nitrate have made mf millipore membrane filters one of the most widely used membranes in analytical and research applications. Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration.

Cellulose acetate ca membranes are made of entirely cellulose acetate polymer. 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. They are also used in applications where maximum protein recovery is critical. 2 and are available in the common pore sizes.

Cellulose acetate membranes are very low protein binding with low extractables and are recommended for applications requiring maximum protein recovery. Naturally hydrophobic ca contains a wetting agent which may be toxic to some sensitive cell lines. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications. Mf millipore membrane filter 0 45 µm pore size.

Cellulose nitrate filters mixed cellulose ester contain a mixture of cellulose nitrate and cellulose acetate a material which assures effective retention combined with high flow rates and optimal colony growth. They are also used in applications where maximum protein recovery is critical. A 0 22 µm pore size non sterile filter validated for air monitoring.
