Splitting droplets


#1

Hey guys, I have been working with the Microdrop automation protocols and would like to split some droplets but this requires me to turn on electrodes simultaneously. Can I just click two electrodes at once (when setting the protocol) to actuate them both simultaneously?

Additionally, does anyone have any tips as the best frequencies or duration for splitting? It is probably device dependent but maybe some general rules for good splits.

Thanks much, starting to have some fun.

Hi Josh,

To split, you can actuate multiple electrodes either in realtime mode
or in a pre-programmed protocol. We generally use 10kHz for
everything. How easy/difficult it is to split depends on the surface
tension of the liquid, the gap height and the distance over which you
are trying to split. The necessary conditions are covered in this
paper:

and various references described therein.

Glad to hear you guys are up and running!
