Techniques are provided for a completely programmable fluidic manipulation without requiring any external control elements or electricity. A chip includes multiple microfluidic channels separated from an outside of the chip by an outer flexible substrate. An apparatus includes a plurality of actuators rotatably connected to a support structure with a recess for receiving the chip. Each actuator includes a plurality of teeth protruding outward, and is positioned so that at least in some angle of rotation a tooth of the actuator extends sufficiently into the recess to compress a microfluidic channel in a chip disposed in the recess. An optional punch card guide is included for guiding a card to contact the actuators. A system or kit includes a punch card on which is formed a plurality of punch features, each configured to engage a tooth of an actuator. Different microfluidic protocols are executed by simply changing the punch card.
