Cellulose Acetate Membrane Filter Paper

Cellulose acetate membranes are very low protein binding with low extractables and are recommended for applications requiring maximum protein recovery.

Cellulose acetate membrane filter paper.

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. The membrane filters are available in different pore sizes and three different material types. Here we explore different filtration properties and how to take a preventative rather than reactive approach minimizing time spent troubleshooting and maximizing efficiency. Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration.

2 and are available in the common pore sizes. A 0 22 µm pore size non sterile filter validated for air monitoring. Cellulose acetate membranes have a very low aqueous extract of. 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.

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. Mf millipore membrane filter 0 45 µm pore size. Cellulose acetate ca membranes are made of entirely cellulose acetate polymer. 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.

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. 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. They are also used in applications where maximum protein recovery is critical. Naturally hydrophobic ca contains a wetting agent which may be toxic to some sensitive cell lines.
