    摘要： A particle sedimentation apparatus includes a rotation body rotatable about a rotation axis and a separation chamber formed in the rotation body, to cause sedimentation of particle suspension in the separation chamber upon rotation of the rotation body. The particles accumulate in a radially outward region of the separation chamber. A flow-rate-determining inflow channel having azimuthal path length with an inflow channel inlet and an inflow channel outlet is formed in the rotation body, the inflow channel inlet being arranged radially further inwardly than the inflow channel outlet, the inflow channel outlet being fluidically connected to the separation chamber and formed to introduce particle suspension into the separation chamber upon rotation of the rotation body. Furthermore, an outflow channel is formed in the rotation body with an outflow channel inlet and an outflow channel outlet, to at least partially drain supernatant liquid formed by sedimentation from the separation chamber.

    摘要： A microdosing device comprises a pressure chamber which is at least partly delimited by a displacer, an actuating device for actuating the displacer, the volume of the pressure chamber being adapted to be changed by actuating the displacer, a media reservoir which is in fluid comunication with the pressure chamber via a first fluid line, and an outlet opening which is in fluid communication with the pressure chamber via a second fluid line. The microdosing device additionally comprises a means for detecting the respective position of the displacer and a control means which is connected to the actuating device and to the means for detecting the position of the displacer, said control means controlling the actuating device on the basis of the detected position of the displacer or on the basis of displacer positions detected during at least one preceding dosing cycle so as to cause the discharge of a defined volume of fluid from the outlet opening. The control means comprises means for controlling the actuating device with a signal of low edge steepness so as to cause the displacer to move from a first position to a predetermined second position, the second position of the displacer defining a larger volume of the pressure chamber than the first position. In addition, the control means comprises means for controlling the actuating device with a signal of high edge steepness so as to cause the displacer to move from the second position to the first position for discharging in this way a defined volume of fluid from the outlet opening.

    摘要： An electrostatically driven diaphragm micropump comprises a first pump bodys a counterelectrode and a second pump body having a diaphragm region. The two pump bodies establish a hollow space bordering on the diaphragm region and are electrically insulated from each other. The hollow space is filled with a medium different from the fluid to be pumped. The pump bodies may consist of a semiconductor material of different types of charge. The medium in the hollow space preferably has a high dielectric constant.

    摘要： A microdosage device comprises a media reservoir used for accommodating a liquid to be dosed, a nozzle connected via a connecting channel to the media reservoir and adapted to be filled via said connecting channel with the liquid to be dosed, and a drive unit for applying, when actuated, to a liquid contained in the media reservoir and in the nozzle a force of such a nature that a substantially identical pressure will be exerted on said liquid contained in the media reservoir and in the nozzle. Flow resistances of the connecting channel and of the nozzle are dimensioned such that, in response to an actuation of the drive unit, a volumetric flow in the connecting channel will be small in comparison with a volumetric flow in the nozzle, said volumetric flow in the nozzle causing an ejection of the liquid to be dosed from an ejection opening of the nozzle.

    摘要： A volume sensor-free microdosing device comprises a pressure chamber which is at least partly delimited by a displacer, an actuating device for actuating the displacer, the volume of the pressure chamber being adapted to the changed by actuating the displacer, a media reservoir which is in fluid communication with the pressure chamber, an outlet opening which is in fluid communication with the pressure chamber, and a control mechanism. The control mechanism drives the microdosing device in such a way that a small change of volume of the pressure chamber volume is effected per unit time by a movement of the displacer from a first position to a predetermined second position, the second position of the displacer defining a larger volume of the pressure chamber than the first position, so as to suck a fluid volume into the pressure chamber, and that, in a second phase, a large volume change of the pressure chamber volume is effected per unit time by a movement of the displacer from the second position to the first position, so as to eject a defined fluid volume from the outlet opening in this way.
