Filtration capsules, Sartobran 150 and 300
Ready-to-use pressure filtration capsules for sterile filtration of media and aqueous solutions with volumes of up to 20 litres (Sartobran 150), or 40 litres (Sartobran 300). The units consist of a polypropylene housing containing a double-layer cellulose acetate membrane (0.2 µm and 0.45 µm). The membranes, which have an area of 150 cm² or 300 cm², have extremely low protein adsorption levels. Autoclavable at up to 134°C. Automatically air vented via an integral PTFE membrane. Sterile and individually packed. With 6 to 12 mm flexible tubing connections (SO) or 1/2 inch tri-clamp (TC).

Membrane filters PORAFIL®MV, white
These cellulose mixed ester membranes are reinforced with a polyester fabric. Their filtration properties are very similar to membranes PORAFIL® CM, however, they are mechanically much more stable.
Membrane filters PORAFIL®CM
Membranes of cellulose mixed esters are ideal for gravimetric analysis. They are particularly suited for aqueous solutions. The hydrophilic membrane is thermally stable to 125 °C and can be autoclaved at 121 °C. This membrane is often used for contamination tests.
Membrane filters PORAFIL®CM, with grid

Membrane filters Nitrocellulose PORAFIL®NC
PORAFIL® NC membranes are made from cellulose nitrate. They are easily wettable and suited for filtration of aqueous solutions. In dry atmosphere these membranes are thermally stable to 125 °C and can be autoclaved at 121 °C.
Membrane filters Regenerated cellulosePORAFIL®RC
Membranes of regenerated cellulose are resistant towards most organic solvents. They are, for example, used for filtration of solvent mixtures and ultrapurification and degassing of HPLC eluents.
Membrane filters Polytetrafluoroethylene PORAFIL®TE
Membranes of polytetrafluoroethylene (PTFE) are particularly suited for aggressive media, since they are chemically inert towards aqueous and organic solutions as well as towards concentrated acids and bases. These membranes are hydrophobic, thus the pressure for filtration of aqueous solutions has to be higher than the breakthrough pressure. PORAFIL® TE membranes can be used at temperatures up to 145 °C
Membrane filters Polyester PORAFIL®PE
Polyester membranes are hydrophilic and particularly suited for fine filtration, dust analysis, aerosol analysis and ultra-purification of solvents.
Membrane filters Polycarbonate PORAFIL®RC
Polycarbonate membranes are mainly used for the determination of AOX.
Membrane filters Cellulose acetate PORAFIL®CA
These membranes of cellulose acetate have a low protein binding capacity and are suited for aqueous and alcoholic media. The membranes are hydrophilic and can be used for hot gases up to 180 °C. They can be sterilised.
