Microfluidic flow controller

Q: How to determine the pressure range to choose?

Fluigent has developed a flow rate calculator to assist users in selecting the appropriate pressure range and microfluidic flow controller for their microfluidic system. They just have to provide details about their setup, including chip geometry, control type, channel and tubing dimensions. generate recommendations for flow rates and pressure ranges based on the provided data. Calculate the pressure range with the calculator.

Q: How can I directly control the flow rate?

Fluigent's Flow Ez technology operates by controlling fluid flow through pressure monitoring, but the company also offers a solution for flow rate monitoring. The Flow Unit is a one-of-a-kind microfluidic flow sensor that accurately and easily monitors flow rates in any microfluidic system. An advanced thermal sensor technology provides complete media isolation and an extremely low internal volume, with no moving parts. Flow rate is then calculated based on thermal desorption, which is directly correlated with flow rate. This bidirectional microfluidic flow sensor can be used in conjunction with a microfluidic flow controller, such as the Flow Ez. To put in a nutshell, the Flow Unit is capable of measuring ultra-low liquid flow rates quickly and with exceptional precision. Learn more about the product.

Q: Is a pressure/vacuum source needed in my setup?

The Line Up flow controllers are not equipped with an internal pressure or vacuum source, but are instead compatible with laboratory-built sources or portable pressure/vacuum generators. Fluigent provides a variety of compact pressure sources, including the Fluigent RX and FLPG Plus models, as well as a compact vacuum source. These user-friendly solutions are suitable for any flow rate and application.

Q: How to program my experiment?

While this microfluidic flow regulator can be used independently, users also have the option of utilizing the OxyGEN software to control various parameters by simply plugging it into any computer. This software allows for real-time monitoring and automation of experiments, enabling users to create or modify time-based protocols with a variety of dedicated functions. These functions range from simple flow rate control to more complex features like conditional paths or looping. By utilizing the OxyGEN software with microfluidic flow controller and automating their experiments, users can improve the reliability and reproducibility of their results.

The Flow EZ^TM, a state-of-the-art microfluidic flow controller

Based on our industry leading experience, Fluigent has developed the patented pneumatic system: the most advanced microfluidic pumping technology available. It is at the heart of the Fluigent’s next generation performance providing the fastest, most stable, and compact microfluidic system In the base configuration, the system controls the pressure or vacuum, and the liquid flow is a function of system resistance, fluid viscosity, etc. The addition of a FLOW UNIT enables one to control or monitor flow rate as well as measure a dispensed volume. The pressure automatically adjusts in the background to maintain the set flow rate.

When combined with the LINK module, the Flow EZ™ flow controller’s capabilities are extended by using Fluigent software to control the system or to generate time based protocols and record data (OxyGEN software).

The Flow EZ™ microfluidic flow controller modules are available in different pressure and vacuum ranges to provide the optimum level of pressure control and resolution. These can easily be combined to match all application requirements or reconfigure the system for a new experimental design.

“We are really happy with Flugent microfluidics control systems: they are very EZ to use; they are also robust and reliable. We want to highlight in particular the user-friendliness of the software (OxyGEN), and the ease with which one can implement their own third-party programs to embed Fluigent controllers to a bigger setup comprising multiple units from different manufacturers.”

Discover the most advanced microfluidic flow regulator

With a compact and modular design, this microfluidic flow controller allows you to set and benefit quickly from the pressure-based flow control advantages for your experiments.

A response time ten times faster compared to syringe pumps.

With the use of pressure instead of mechanical action, the Flow EZ^TM microfluidic flow controller gets a responsiveness ten times faster than syringe pumps. A low response time allows users to quickly execute operations such as stop flow and pressure/flow rate steps.

Control flow rate with the benefits of responsive, pulse-free flow

Pulse-free flow is critical for generating high quality and repeatable results. The Microfluidic flow controller integrates the all-new DFC (Direct Flow Control) algorithm. This allows users to set a flow rate directly on the instrument display. The applied pressure will automatically adjust to maintain the flow rate.

“We came to Fluigent when we were building an automated microfluidic platform for screening chemical reactions. Fluigent products are powerful in precise control of the flow conditions and can guarantee the performance of our platform. The pump system is user-friendly and can be extended to complex experimental systems where multiple pumps are needed. The above merits have made our experimental design process smooth and easy.”

“We connect the chips to the Fluigent pump system because that allows us to deliver more complex flow environments […] and visualize live on the microscope.”

Martin Knight | Professor of mechanobiology at Queen Mary university of London

Focus on the microscope. No PC required

Instead of looking at the PC, users can keep their eyes on the microscope, adjusting the control dial with one hand. In this stand-alone configuration, the device allows for pressure or flow rate control and volume dispense, making it ideal for benchtop use.

“The Fluigent microfluidics flow system has allowed us to expand our static cell models into a model of cells under flow that represents in vivo conditions more closely. Through this addition, we have been able to increase our publication output, with microfluidics at the heart of this research.

The FlowEZ allows us to manipulate flow rates quickly that allows us to introduce various activators and inhibitors to our cells, and create a system of recirculation that minimizes volume requirements, sample loss, and removes the need for users to be present for the experiment to run for hours at a time.”
