Abstract

The present invention relates to a liquid droplet ejection apparatus which is configured to selectively dispense a liquid droplet having a large flow rate and a liquid droplet having a small flow rate in a precise manner. The liquid droplet ejection apparatus according to the present invention comprises: a pneumatic ejector for ejecting a liquid droplet having a first flow rate; and an electronic pipette for ejecting or suctioning a liquid droplet having a second flow rate identical to or lower than the first flow rate. The pneumatic ejector comprises: i) a storage chamber for storing a liquid; ii) an air tank which is connected to the storage chamber through a first air pipe and which provides the storage chamber with compressed air in order to push the liquid in the storage chamber to the outside; and iii) a first nozzle which is connected to the storage chamber through a liquid pipe and which receives the liquid pushed from the storage chamber and ejects a liquid droplet.

Description

technical field [0001] The present invention relates to a liquid drop discharge device, in more detail, to a liquid drop discharge device capable of selectively and accurately dispensing large-flow liquid droplets and small-flow liquid droplets. Background technique [0002] The droplet discharge device is a device that discharges a solution onto a target such as a substrate in units of extremely small droplets (water droplets). Such droplet discharge devices are widely used in a wide range of industrial fields, and recently, with the integration of bioindustry and mechanical engineering, research on droplet discharge devices for bio-devices has been actively conducted. [0003] Conventional liquid droplet ejection devices for biological instruments have a simple structure mainly using an electric pipette. By using a droplet discharge device equipped with an electric pipette, it is possible to dispense a small flow rate of liquid droplets with high reproducibility. [0004...
