Hi,

  I have a chip that will have a sheathed flow. I will be controlling
the flow rates of each flow by a syringe.  The sheathed flow will have
one syringe and split off with a Y-connector.  How can I keep the flow
rates of each flow equal?  Is there a common setup for actuating the
syringe push at the same time with equal force?

Any hints would be appreciated.

Thanks.
