Abstract
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.
