System for controlling the flow of a fluid through a substrate
First Claim
1. A system for controlling the flow of a fluid through a substrate having first and second surface and at least one area with a plurality of through-going capillary channels, characterized by a housing having a chamber for receiving the substrate, means for generating a pressure difference over the substrate to transport the fluid from the first to the second surface and vice versa through the channels of said at least one area, and means for maintaining the pressure difference at a controlled level during the transport of the fluid through the channels.

Abstract
A system is described for controlling the flow of a sample fluid through a substrate having first and second surfaces and at least one area with a plurality of through-going capillary channels. The system comprises a housing having a chamber for receiving the substrate and a pressure differential generator capable of generating and maintaining a pressure difference over the substrate.
