摘要： A microdosing apparatus comprises a fluid conduit having a flexible tube with a first end for connecting to a fluid reservoir and a second end where an outlet opening is located. An actuating device with a displacer with adjustable hub is provided, by which the volume of a portion of the flexible hub can be changed to thereby dispense liquid as free flying droplets or as free flying jet at the outlet opening by moving the displacer between a first end position and a second end position, whereby the tube is partly compressed in the first or the second end position. In other words, a microdosing apparatus comprises fluid conduit having a portion along which a cross section of the fluid conduit is variable by an actuating device to effect a change of the volume of the fluid conduit. A ratio of a fluidic impedance between the position of the actuating device and the outlet opening to a fluidic impedance between a first end of the fluid conduit and the position of the actuating device is variable by changing the position of the actuating device, so that a dosing volume dispensed at the outlet opening is variable thereby by at least 10%.

摘要： A microdosing apparatus and method include a fluid conduit having a flexible tube with a first end for connecting to a fluid reservoir and a second end where an outlet opening is located. An actuating device with a displacer with an adjustable stroke is provided, by which the volume of a portion of the flexible tube can be changed to thereby dispense liquid as free flying droplets or as a free flying jet at the outlet opening by moving the displacer between a first end position and a second end position, whereby the tube is partly compressed in the first or the second end position.

摘要： A changeable pipette tip includes a first end having a fluid opening and a second end having a pipe elastic in the radial direction having an orifice. The orifice and the fluid opening are in fluid connection. The first end is designed to be coupled to a matching coupling unit of a pipetting unit such that liquid may be sucked into the fluid area through the orifice by an actuating unit in the pipetting unit. In order to eject liquid as free-flying droplets or as a jet from the orifice of the pipe elastic in the radial direction, a volume change of a portion of the pipe elastic in the radial direction is effected.
