* depending on the liquid
The microdrop technology uses the
principle of the ink jet printing technology. The core of the microdrop
dispensing head consists of a glass capillary which is surrounded by a
tubular piezo actuator. At one end the capillary is formed to a nozzle
(diameter 30 to 100 µm). Applying a voltage pulse, the piezo actuator
contracts and creates a pressure wave which propagates through the
glass into the liquid. In the nozzle region the pressure wave
accelerates of the liquid. A small liquid column leaves the nozzle,
breaks off and forms a droplet which flies freely through the air.
Depending on the nozzle sizes (30 to 100 µm) volumes of 25 up to 500 pl
(corresponding to drop diameters of 35 to 100 µm) are generated.
You can find this Microdrop Technology integrated in the AD-K- and MD-K-dispenser series.
