Tangential Flow Filtration Membranes

Ultrafiltration (UF) Membranes

Delta Regenerated Cellulose Membrane
Delta regenerated cellulose membrane offers high flux and selectivity. The membrane has been specifically developed to minimize protein binding to the surface and interstitial structure of the membrane. Inherently hydrophilic, this membrane shows low protein adsorption properties and is optimal for processes involving very hydrophilic proteins. Delta regenerated cellulose membrane shows low fouling characteristics, allowing a constant performance or flux during a production run. It is easy to clean and typically recovers normalized water permeability (NWP) by using only 0.8N saline solution.

Omega™ PES Membrane
Pall's Omega polyethersulfone (PES) membranes offer high flux and selectivities. They have been specifically modified to minimize protein binding to the surface and interstitial structure of the membrane. This polymeric membrane is stable against biological and physical degradation due to the unique chemical properties of PES. Omega membranes are cast on a highly porous, non-woven polyolefin support. They have an anisotropic structure, a thin skin-like top layer with a highly porous underlying support. The structure of the skin determines the porosity and permeability characteristics of the membrane and can typically be cleaned quicker and easier than membranes with a uniform, sub-micron depth structure. This membrane is compatible with acids, bases and a variety of other cleaning agents. Omega membranes are available in a wide range of nominal molecular weight cutoffs (NMWC).

Microfiltration (MF) Membranes

Supor® TFF Membrane
Supor TFF membrane is a polyethersulfone membrane with a uniform depth structure. The membrane porosity is optimized for microfiltration TFF applications including harvest, concentration and clarification of cell cultures and fermentation broths. It is currentlly available in 0.1, 0.2, 0.45, 0.65 micron pore size membranes. Use Supor TFF membranes to harvest bacterial, mammalian, and insect cells; separate red blood cells from hemoglobin; and, clarify yeast broth and bacterial lysates.
