Abstract
In a microfluidic system, a magnetic clamp for sealing a flexible microchannel chip includes a base formed from a magnetically-attractable material. The base supports a window for viewing the face of the microfluidic chip. A ring with magnets uniformly distributed around it is disposed over the base. A transparent disk attached to the top of the ring has an inlet and an outlet for introducing and removing a fluid medium into a cavity defined the disk, the window, the center opening of the ring and the base. An elastomer cushion is attached to the inner surface of the disk. The magnetic force between the base and the magnets on the ring compresses the cushion against the microfluidic chip so that the microchannels are sealed against the window with a uniform and reproducible pressure.
