  • Connector
    Patent number: 7338088
    Abstract: A connector is provided for selectively coupling one or more lines or wires (19?, 19?) to a receiving and/or transporting device (27). The connector comprises at least one line or wire receiving ferrule (7) having a plurality of line and/or wire receiving holes (17?-17?) each capable of receiving one of said one or more lines or wires (19?, 19?), wherein said connector further comprises a body (3) for receiving said ferrule (7) and clamping means (9, 11) for exerting a force on said ferrule (7) in order to simultaneously exert a line or wire clamping force on all said line and/or wire receiving holes (17?-17?). In this way all the fluid lines or wires can be clamped at the same time.

  • Liquid microvolume handling system
    Patent number: 7323345
    Abstract: The present invention relates to a microfluidic device comprising a microchannel (2, 4) providing for solvent contact between an open microarea (MA) carrying a microvolume (1) of a solvent and a reservoir (3) for the solvent, said reservoir (3) and said microchannel (2, 4) being adapted so that solvent evaporated from said microarea (MA) is continuously replaced by solvent from the reservoir (3) through said microchannel (2, 4). It further relates to method for replacing solvents evaporating from a microvolume (1) of solvent placed in an open microarea (MA) of a microfluidic device, wherein replacement is continuously taking place via a microchannel (2, 4) that transports solvent to the microarea (MA) from a solvent reservoir (vessel) (3). The device and method are suitable for preventing the desiccation of samples.

  • Integrated microfluidic element
    Patent number: 6322753
    Abstract: An integrated microfluidic element (1) composed of two juxtaposed plates (3, 5) bonded together, wherein at least one plate (3) has an etched structure or pattern of channels (7) on the surface facing the other plate (1) to form sealed micro channels (7), said element having micro spacers or posts (11) distributed over the etched surface of said one plate outside of said etched structure or pattern, and walls (9) surrounding said channels (7), said walls (9) having a height equal to that of said spacers or posts (11); and a method for the manufacture of such integrated microfluidic element.
