FIG. 1.
(a) Low-cost microfluidic flow controller for controlling flows through four fluidic inlets. (b) Schematic of pressurized sample vial. A pressure (Po) is applied to a cryovial and fluid flows through a series of tubing resistors (R1), a capillary resistor (Rcap), R2, into the device (Rchip) and exiting through outlet tubing (R3) at a flow rate Q. (c) Hydraulic circuit diagram of the fluidic system.
