Sartorius Membrane Filters

By Sartorius

Sartorius produces a wide variety of microporous membranes that are especially designed, developed and manufactured to meet differing needs of the biotechnology industry.

Backed up by many decades of experience in membrane manufacturing and by utilizing the most state-of-the-art production equipment on the market, Sartorius guarantees excellent performance and consistent quality.

Sartorius’ membranes are available in a wide variety of different pore sizes and structures, as well as surface properties to serve nearly unlimited selectivity of separation. Microporous membranes can be composed of various polymers that differ from one another in their chemical and physical properties. Together with the characteristics of the filter pores these polymer properties govern the results in many filtration applications.

Cellulose Nitrate (Mixed Cellulose Esters)

Cellulose nitrate membrane filters are hydrophilic, have high flow rates thanks to their symmetrical structure and are compatible with aqueous solutions (pH 4 – 8), hydrocarbons and several other organic solvents. These cellulose nitrate membranes are available in different pore sizes from 0.2 µm to 8 µm.

Polytetrafluoroethylene

PTFE filters are permanently hydrophobic. These membrane filters feature excellent chemical compatibility (pH 1 to 14) so they are also used for filtration of solvents and acids that cannot be filtered using other filter types due to a lack of or limited compatibility.
