<p>The present invention is an adsorber membrane and a device containing one or more such membranes. Both the membrane and the device have a Peclet number (Pe) of at least 100. The membrane and the device are designed for the removal of trace contaminants in protein containing streams such as exist in the biopharmaceutical industry. A preferred membrane has tight pore size distribution and high permeabilities that allow for high throughput separations. A device of the present invention can contain a flat sheet membrane such as a pleated filter, a tangential flow filter or a spiral wound filter. Preferably, the device is formed in a stacked disk arrangement where one or more layers of membrane are sealed to each of the two large surface of the disk. One such device is formed of a series of disks, each disk having eight layers of membranes sealed to each of the two large surfaces of the disk. These disks are placed within a sealed capsule having an inlet on one end and an outlet on the other. The disks are sealed so that all fluid that exits the outlet does so by having first passed through the membranes on one side of a disk.</p> |
