Microfluidic setup Flow Rate and Pressure Calculator.
Choosing the right microfluidic controller is the first step in developing any microfluidic experiment, but it is not always an easy task. In a microfluidic set-up there are two kinds of flow resistances: external flow resistances (tubing and fittings) and internal flow resistances (microchip design). Both will determine the necessary pressure to achieve the desired flow rate.
To help our clients choose the right instrument, Fluigent has designed this calculator to estimate the resistance of most microfluidic setups. Detailing your setup below will determine which pressure range to work with and the recommended microfluidic pump.
Control Type & Unit
Enter the dynamic viscosity of the fluid used in the microfluidic experiment. Note that water (at 20°C) dynamic viscosity is 1 mPas.s.
Chip microchannel dimensions
Enter the chip channel dimensions and each section. Each microchip design has a different section number. Use the channel identification (letters from a to e) in the SETUP TYPE panel above to match the chip section accordingly. The resistance is calculated for each channel section of the chip.
CHANNEL LENGTH (mm)
CHANNEL RESISTANCE (unit)
Enter the tubes dimensions and each section length. Tubing may be from or to the chip, refer to the introductory image for explanation. Use the flow inlet and outlet identification (numbers from 1 to 4) in the SETUP TYPE panel above to match the tubing section accordingly. The resistance is calculated for each tube section of the setup.
TUBING LENGTH (mm)
Depending on the control type selected above, enter the pressure or flow rate values for each tubing or microchip channel. The flow rate or the pressure are calculated and displayed. Refer to the SETUP TYPE panel to identify the according tubing or microchannel section.
