Cellulose Acetate Membrane Filter Paper

With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications.

Cellulose acetate membrane filter paper.

Cellulose acetate ca membranes are made of entirely cellulose acetate polymer. 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. 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 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.

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. The membrane filters are available in different pore sizes and three different material types. They are also used in applications where maximum protein recovery is critical. Cellulose acetate ca membranes are made of entirely cellulose acetate polymer.

Whether its cell culture protein research water testing bioprocess design or qa qc testing of beverages filtration will play a role in your lab s daily routine and thermo fisher scientific has the tools you need. Cellulose acetate membranes have a very low aqueous extract of. Here we explore different filtration properties and how to take a preventative rather than reactive approach minimizing time spent troubleshooting and maximizing efficiency. Mf millipore membrane filter 0 45 µm pore size.

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. The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. Naturally hydrophobic ca contains a wetting agent which may be toxic to some sensitive cell lines.

Cellulose acetate membranes are very low protein binding with low extractables and are recommended for applications requiring maximum protein recovery. A 0 22 µm pore size non sterile filter validated for air monitoring. Filtration is an integral piece of nearly every workflow of every lab.
