Appl. No.:

11/010804

Inventors:

John Connors - Shrewsbury MA, US

International Classification:

B01D063/00

US Classification:

210321760, 210321850, 210488000

Abstract:

Filtration devices that include filtration cassettes that feature a plurality of stacked subassemblies, wherein at least one of the subassemblies includes a porous membrane having a front side and a back side and a perimeter; and an overmolded frame that encapsulates the membrane around the perimeter of the front side and the back side of the membrane; wherein the overmolded frame forms at least one retentate port, at least one feed port, at least one filtrate port, and a flow channel proximate a perimeter of the frame; and an overmolded plastic jacket that penetrates the flow channels of the subassemblies to seal the stacked subassemblies; and methods for making the filtration device and cassettes.

Appl. No.:

11/518803

Inventors:

John Connors - Shrewsbury MA, US

International Classification:

B01D 63/00

US Classification:

210321750

Abstract:

A filtration cassette is described. The filtration cassette can include one or more filtrate channel spacers and one or more feed channel spacers. Each of the feed channel spacers and each of the filtrate channel spacers define an open interior volume bounded by an inner perimeter and include at least one feed port and at least one filtrate port. The filtrate channel spacers and the feed channel spacers are arranged such that the feed ports and the filtrate ports are positioned in respective alignment. The filtration cassette further includes one or more membranes disposed between the filtrate channel spacers and the feed channel spacers, and one or more retaining members at either end of the filtration cassette. A thin film of adhesive binds together the filtrate channel spacers, the feed channel spacers, and the membranes.

International Classification:

B01D 63/00

US Classification:

210321840, 210335000, 210224000

Abstract:

A filtration device having at least one filter packet and a retainer is described. The filter packet includes a membrane having at least a first opening therethrough. The filter packet further includes a retentate screen in fluid communication with the first side of the membrane and a filtrate screen in fluid communication with the second side. The retentate screen includes a permeable material and a seal around an outer perimeter of the permeable material. The permeable material has at least a feed port-defining zone in fluid communication with the first opening. The filtrate screen includes a permeable material and at least a feed port-defining zone in fluid communication with the first opening. The feed port-defining zone of the filtrate screen includes a seal around a perimeter thereof. The filtrate screen has a perimeter open to a filtrate collection area.
