This system is designed to generate a stable and pulseless flow for a wide variety of microfluidic applications.

The Dual AF1 has a pressure range from -700 mbar to 1bar. It can be used both as a vacuum source or a pressure source and enables you to switch from vacuum to pressure on the same channel.



Vacuum & Pressure Pump

This instrument is designed to be perfectly compatible with the AF1 Dual Vacuum & Pressure Controller in order to provide the control and accuracy you need. This instrument can also be used independently.


Regulate negative & positive pressure

This instrument covers a pressure control range from -700 mbar to 1000 mbar. It has to be linked to an external pressure source such as the AF1 Dual Vacuum & Pressure Generator in order to supply regulated vacuum and pressure.

Range available :

  • 200 mbar
  • 1.6 bar
  • -700 mbar/+1 bar

Fully customizable & OEM

The AF1 can be modified to fit almost all specific microfluidic requirements. An OEM version is available and the instrument is upgradable. Buy it today and add functions later.

High volume

Piezo technology enables fast pressurization of tanks up to 1 liter and enables to set up long term or high flow rate microfluidic experiments.

Flow rate control (optionnal)

AF1 pressure pump can be coupled with a flow sensor. Using our feedback loop, you can monitor and control flow rate in your microfluidic setup while keeping stability and responsiveness of pressure driven flows.

AF1 microfluidic pressure and vacuum pump

Manual or USB software

For early stage scientific experiments, monitor and control pressure using the front panel knob and screen. With the AF1, you can switch from manual to USB control at any time using the Elveflow® Smart Interface.

Elveflow® instruments are built around a common application which facilitates navigation from one instrument to another. Our Smart Interface enables you to control your setup after a few minutes of training.

Complete setup synchronisation

The AF1  is equipped with internal & external trigger connectors and  can thus be synchronized with any other Elveflow® product, a microscope or any electrical instrument… It also enables the synchronization of up to 16 instruments simultaneously.

USB pressure pump software module

Elveflow® instruments are assembled around a software application that facilitates the switch from one instrument to another. Thanks to an intuitive interface, the Elveflow® Smart Interface enables the use of Elveflow® instruments from the simplest commands for beginners to the most complex manipulations for experts… read more

Our USB Software enables you to control complex flow and pressure profile.

The user can apply constant pressure of flow and ramp, but also sine, triangle or square waveforms with desired parameters. A graphic allows monitoring of either the applied pressure or of the flow rate (using a flow sensor or of any external sensor).

DLL and libraries

Control your experiments through C, Python, Matlab®, Labview® or the Elveflow® Smart Interface.

> Configurations
Store pressure configurations and switch from one to another in a second

> Edit functions
Complex pressure and flow rate profiles such as ramp, sine, square and triangle can be defined.

> Flow control
When used with a flow sensor, a feedback loop with adaptable sensors allows for a direct control of the flow rate.

> Display & save data
Real time pressure and flow rate are monitored and can be saved for later studies.

The liquid is smoothly and precisely injected onto the microfluidic chip using suction force. The optional module Dual Vacuum & Pressure Generator is designed to replace vacuum and compressed air systems. The dual pressure unit produces positive and negative pressure and is perfectly fitted for the Dual AF1.


Fast and accurate pressure and vacuum control.


Control pressure using your computer or the instrument’s front panel knob.


The tank protects your AF1 from liquid back flow and can also function as a microfluidic reservoir when using the AF1 as a pressure source (compatible with Eppendorf, Falcon or bottle ).
