Features & Benefits

If you need stability, speed and the most precise control over the fluids of an experiment, this system is the best on the market20 times more precise and 10 times faster than other flow controllers on the market, and pulsation-free).

This pressure control system is perfectly fitted to microfluidic research. It is the only microfluidic flow control system using Piezo technology and blazing fast flow changes in your microdevice.

Each channel can be coupled with a Microfluidic thermal flow sensor (MFS) or the Coriolis flow sensor (BFS), suited to both liquid and gas, to ensure a precise control of the flow rate.

The OB1 MK3+ Flow Controller is sold with a 2-year warranty.  

OB1 how it works - Darwin Microfluidics

Advantages of Pressure control in microfluidics

Compared to a syringe pump, the OB1 Pressure Controller provides a much smoother and faster control of the flow.

  • Fast settling time (down to 40 ms)
  • High stability and pulseless flow
  • Possibility to handle fluid volumes of several liters
  • Enable both flow and pressure control when used with a flow meter 

Elveflow OB1 software allows an intuitive control of your microfluidic instruments in few clicks. It is thought both for basic control and complex tasks thanks to the use of the Sequencer. 

From the software main windows, you can control the pressure (and the flow rate when equipped with a flow sensor) for each channel, set predefined or custom patterns, save configurations to reuse them in the future.

You can also record any data  in a user-defined time interval up to 100Hz. The recorded data are stored files that can be saved and analyzed in the application of your choice, and visualized as a graph in the software.

You can download ESI software and access the SDK here.


Optional Flow rate control

This control system can be used with the Microfluidic thermal flow sensor (MFS) for a fast and precise regulation of the flow rate. Thanks to the consistent speed of this system, both speed and precision can be achieved, even when working with multiple independant channels. The feedback loop (PID) allows you to monitor and control the flow rate of the setup, and still keep stability and responsiveness of pressure driven flow. 

This system enables fast pressurization of tanks up to a volume of 1 liter, so that long term microfluidic experiences can be set up. 

  • Pressure stability: 0,005% - 100 µbar - 0,0014 psi
  • Response time: 9 ms
  • Setting time: 40 ms
  • Pressure sensor resolution: 0,006% - 122 µbar - 0,00017 psi
  • Input pressure: min 1,5 bar - max 10 bar
  • Pressure range of each outlet: 200 mbar, 2 bar, 8 bar, -900mb/+1bar,  -900mb/+6bar
  • Liquid compatibility: any aqueous or or organic solvent, oil or biological sample solution can be propelled
  • Pressure source: non corrosive, non explosive, dry and oil-free gases, e.g. air, argon, dinitrogen, carbon dioxide, etc...
