An automated microdoser DT-03 serves for precision supply or bleeding of liquids with the help of changeable standard syringe (disposable plastic syringe of volume 1, 2, 5 or 10 ml). The microdoser can be employed, for example, for drop formation at the limiting wetting angle experimental measurement, for feeding solutions with solvent or active ingredients, for replenishing the monomolecular film in Langmuir—Blodgett trough etc. The microdoser features reversable motion of the leading rod that allows to draw the liquid back into the syringe.

The device design provides simple routine for the syringe installation/change and a possibility to move the leading rod manually. The microdoser mechanism can be deflected to angle 75° back from its vertical position on the supporting stand.

For the microdoser positioning in horizontal plane relative base (substrate), it can be employed together with the XY positioning stage. Stepper motors of both the microdoser and XY positioning stage can be driven from control program run on host PC.

The microdoser DT-03 driving mechanism is unified with that of dipper VT-04 that allows their mutual conversion by simple change of the unit front panel.
