Abstract:
A flow cell of the type that may be used in the synthesis of arrays of DNA probes and the like, comprising:(a) a transparent substrate with two parallel flat surfaces, one of the surfaces forming an active surface of the substrate; (b) a base having a central window opening and a registration surface against which the substrate is mounted; (c) a gasket mounted on the active surface of the substrate and having a central opening defining an active area surrounded by material of the gasket, an inlet extension opening extending from the central opening of the gasket, and an outlet extension opening extending from the central opening of the gasket; and (d) a press block having an engagement surface which is engaged against the gasket to press the gasket against the substrate mounted on the base to form a sealed volume defined by the periphery of the openings in the gasket and the active surface of the substrate and the engagement surface of the press block.
