ELECTRIC CHARGE CONCENTRATION TYPE LIQUID DROPLET DISPENSING DEVICE HAVING NON-CONDUCTIVE CAPILLARY NOZZLE

摘要

An electric charge concentration type droplet dispensing system having a non-conductive capillary nozzle is provided to allow ejection of fine droplets depending on electric control signals, and to maintain the surface shape of droplets at the nozzle tip without using an additional driving unit. A droplet dispensing system comprises: a downwardly installed non-conductive capillary nozzle(10); a pump linked to the non-conductive capillary through a sealed fluid pipe(51) and generating a negative pressure to reduce the effect of the gravity on the solution(25) inside the nozzle and the fluid pipe; and an open type voltage application unit(40) for applying a voltage to the solution.
