Abstract
Provided is a droplet discharging device that can precisely dispense large flow rate of droplets and small flow rate of droplets selectively. The droplet discharging device according to the present invention includes a pneumatic discharger for discharging a droplet having a first flow rate, and an electronic pipette for discharging or sucking a droplet having a second flow rate equal to or smaller than the first flow rate. The pneumatic discharger includes, i) a storage chamber for storing a liquid, ii) an air tank connected to the storage chamber through a first air pipe and supplying compressed air to the storage chamber to push the liquid of the storage chamber outside, and iii) a first nozzle connected to the storage chamber through the liquid pipe and receiving the liquid pushed out of the storage chamber to discharge droplets.
