The performance of your microfluidic flow control instruments depends on your experimental conditions (tank volume, output pressure, computer configuration, operating system, microfluidic setup… ). Our microfluidic specialists will gladly advise you on choosing the best equipment for your needs.
OB1 MkII typical stability*: 0.005% s.d.
Pressure stability over time at 150 mBar OB1 200 mBar output (2 mL output volume) and electro-mechanical technology (2 mL output volume). Real output pressure stability measured at 150 mBar with an external high accuracy pressure sensor (Druck DPI150)
* Short term stability measured for 1 min with a high accuracy sensor (Druck DPI150), excluding long term drift due to aging and environmental factor variations.
For demanding microfluidic researchers, maintaining a stable flow in their chip is essential – the pressure stability in a microchip is directly related to flow stability in the microchannel.
With the OB1, you will get a flow stability that is 20 times higher than other existing technologies available for microfluidic research (0.005% of the full scale).
Note that the pressure value which is displayed in your Elveflow software provides a visual indicator of the applied pressure changes.
The OB1 MKII internal pressure sensor used by the Elveflow software to display pressure has an additional electronic noise (0.05%) which does not rely on a real output pressure variation. As shown in the figure below, pressure noise in your microfluidic device will be 10 times less than the pressure displayed in your Elveflow interface.
* Output Stability measured at 150 mBar with an external high accuracy pressure sensor (Druck DPI150) simultaneously displayed with the Elveflow interface monitoring.

Revolutionizing Microfluidics with Acoustic Particle Manipulation
This short note will introduce you to the key takeways about microfluidic T junction among other microfluidic junctions.
Fluid mixing at microscale is of importance for many fields of application. This short review summarises the key takeaway aspects of fluid mixing at microscale.
In the past two years, several new microfluidic syringe pump systems have changed the use of syringe pumps in microfluidic experiments.
This review presents a few examples of applications where magnetic flux sources, magnetic particles and microfluidics are combined in order to perform particle sorting and handling.
In microfluidic laminar flows, traditional turbulent mixing between two liquids cannot occur. However, controllable and fast mixing is critical for microfluidic and lab-on-chip devices. So different mixing techniques were developed and are here presented.
There are three main classes of systems to control liquid motion in microfluidic and nanofluidic devices.
One of the great challenges for researchers using microfluidics is miniaturizing analysis processes in very small microchip.
Microfluidic flow controllers are designed to control flows in microfluidic chips.
Despite their sturdiness & simplicity, syringe pumps are often problematic in microfluidics.
Liquid flow sensors are a compulsory element of microfluidic systems requiring a control of the sample volume dispensed and/or, obviously, the sample flow rate.
What are the strengths and weaknesses of each type of microfluidic flow control system? Pressure controller, syringe pump...?
Fast medium switch in microfluidic channels is generally a required technique to perform a wide range of biomedical and chemical microfluidic assays, such as the analysis of living cells in vitro, particle washing, etc.
Outside of conventional syringe pumps which generate flow oscillation at low flow rate and long settling time, we can now find syringe pumps like the NE-1002X which is dedicated to microfluidic experiments.
Common syringe pumps have two major drawbacks when it comes to research in MICROFLUIDICS: RESPONSIVENESS and flow OSCILLATION/PULSATILE FLOW. Recently, some syringe pump manufacturers have developed...
