Highlights
Low flow rates
As the microfluidics field evolves, it stretches the capabilities of current instruments. The demand for low flow rates is an example. Current flow sensors cannot read below 1 µl/min accurately. Galileo was designed to bridge this technological gap, giving you accurate reading below 1µl/min.
It was also designed to work with all types of pumps, such as pressure-driven flow controllers and syringe pumps, as can be seen in the schematics below.
Clogging detection
Microfluidics systems are complex because they depend on several parts put together: pumps, tubings, connectors, chips, sensors, valves, you name it. And when something goes wrong, a lot of time is lost trying to troubleshoot the whole system. To make life easier, our microfluidic flow sensor, Galileo, can alert you if the problem is coming from its internal fluidic path.
Drift Detection
Through empirical observation, our team realised that flow sensors drift during long experiments due, for instance, to modification of the inner flow path of the sensor, i.e. biofouling by the accumulation of particles on the walls of the sensor.
So we developed a flow sensor that can detect if modifications are occurring within its channel walls. When drift occurs, it gives out a visual alert, so you can have 100% confident in your readings and take measures to correct any drift by easily replacing the cartridge.
The Microfluidics Innovation Center developed Galileo, a highly-performant microfluidic flow sensor with proven high accuracy, precision, and reliability.
The technology provides a robust and versatile solution for microfluidic applications thanks to its many features:
- <5% flow rate accuracy for any given range
- Configurable sensing ranges from 0.5 to 10,000 µL/min
- Fully replaceable cartridge format for range configuration and flow path replacement
- Automatic detection of internal clogging and measurement drift (e.g., biofouling)
- Bi-directional flow rate measurement (positive & negative)
- Galileo user interface and LCD screen for direct flow rate monitoring
The Galileo Operation video offers clear step-by-step instructions on easily connecting the Galileo flow sensor and navigating the software interface. The video also includes a live demonstration of the sensor in action and a detailed explanation of the indicator lights.

Can the cartridges be reused?
Yes, depending on your application. The flow sensor cartridges can be reused if there’s no alert of clogging, or if you face no problems of cross-contamination in your experiments.
With which types of pumps can the sensor be used?
Our microfluidic flow sensor can be used with all types of pumps, as it has an independent software that doesn’t depend on the flow generating system.
