摘要： Devices and methods are provided using microfluidic devices for manipulating small volumes and determining a variety of chemical and physical events. The devices rely upon an opening to the atmosphere of a small volume in a zone, where a sample is placed in the zone where evaporation can occur. The zone is maintained in contact with a liquid medium that serves to replenish the liquid in the zone and maintain the composition of the mixture in the zone substantially constant. The diffusion of components in the zone is restricted during the course of the determination by the liquid flux into the zone.

摘要： A pipetting apparatus (1) comprises a fluidic space (7), to which a pressure transducer (11) with a pressure sensor (12) is attached with a gas filled space (15). The fluidic space (7) is defined by a pipette tip (2), a first tubing (5) that connects the pipette tip (2) to a pump (4), and an active part (6) of the pump (4). The pipetting apparatus (1) according to the present invention is characterized in that the pipetting apparatus (1) further comprises an impulse generating means (16, 18, 19) that is in operative contact with a column (10) of system liquid (8) inside the fluidic space (7). The impulse generating means (16, 18, 19) is designed to induce a vertical movement in this system liquid column (10), which results in a pressure variation in the gas filled space (15) that is pneumatically connected with the fluidic space (7). This pressure variation—as recorded with the pressure transducer (11) and as processed by a first data processing unit (13) during utilization of this pipetting apparatus—is taken as an indicator for the detection of penetration or of quitting of a surface (17) of a liquid, with an orifice (3) of the pipette tip (2), of which liquid an amount is to be aspirated and dispensed. This pressure variation is also taken as an indicator for the detection of the presence or the absence of gas bubbles in the system liquid (8) contained in the fluidic space (7) of this pipetting apparatus.

摘要： The present invention provides for methods and apparatus for locating a capillary channel that is disposed within a lab chip. The method provides for scanning the channel with a light source, monitoring the resulting light at the edges of the lab chip, and interpreting this information whereby the light detected at the edges of the lab chip can be used as a means for characterizing the location of the side walls of the channel within the lab chip. The apparatus provides for a carriage system to which a light source and the lab chip are attached. It also provides for one or more scatter detectors directed towards the edges of the chip and connected to a computer processor for purposes of analysis.

A base unit with cartridge accommodation sites and at least one electrode array with electrodes works with a cover plate at the sites and a control unit for controlling selection of the electrodes and for providing them with voltage pulses for manipulating liquid droplets within the cartridges by electrowetting. The cover plate has an electrically conductive material that extends parallel to the array. A selection of disposable cartridges and a method for manipulating samples in liquid droplets that adhere to a hydrophobic surface can be used with the system.
