High-speed droplet break-off video

This video displays the jet-in-air stream that has been captured on the Epics Elite (BC) of the PUCL in 2003 by modifying the frequency of the piezzo. By changing the frequency of piezzo vibration, the location of the last attached droplet is modified (up or down). For sorting, we try to get the position of the last attached droplet as close as possible of the flow cell tip.
