Microfluidic Calculation Tools

A collection of practical microfluidic calculation tools for estimating flow rate, pressure drop, hydraulic resistance, droplet generation and other key design parameters during microfluidic system design and particle development.

Calculator - Microfluidic Resistance

This calculator estimates microfluidic resistance from channel geometry and fluid viscosity. It supports circular and rectangular channel profiles and can help with early-stage pressure-flow planning, pump selection and microfluidic system design.

Details

Calculator - Microfluidic Flow Rate & Pressure Drop

This calculator estimates back pressure, flow rate and Reynolds number for laminar flow in microfluidic channels. It supports constant flow rate and fixed pressure systems using Hagen-Poiseuille-based calculations.

Details

Calculator - Droplet Generation Rate

This calculator estimates droplet production rate and product volume from chip and operating parameters.

Details

Calculator - Poisson Distribution

You can use the calculator below to determine what the occupancy distribution will be for a particular concentration of cells or particles in your starting sample given the size of the microfluidic droplets in which they are being encapsulated.

Details

Calculator - Droplet Properties

Use this calculator to easily convert between diameter and volume. If you are preparing a bulk sample of droplets you can use this calculator to also determine the number of droplets produced from your starting volume, or the sample volume required to provide a given number of droplets.

Calculator - Solvent Extraction

The calculator on this page predicts the final size of a particle based on the concentration of polymer in, and size of, the starting droplet.
