Abstract
A filter system particularly useful with small sample volumes includes first and second housing sections with a flow channel extending therebetween. A membrane filter forms one boundary of the flow channel. A pair of reservoirs, one for feed and the other for permeate collection, are integrally formed with the first housing section. A fluid communication path is established from the first section to the second section and then through means of a deformable chamber to the flow channel. The deformable chamber is adjacent to a rigid surface that is integral with one of the housing sections and in this manner is adapted to pump fluid through the system when interfacing with a pump.
