A pressure and a vacuum controller mixed in a skillful microfluidic flow controller for outstanding performances

The OB1 Mk3combines a pressure and a vacuum controller on the same channel. This characteristic allow researchers to precisely monitor the position of an object within a microfluidic channel and to master microfluidic flow control.

"Microfluidics, like microelectronics in its time, have required to create new highly efficient specific instruments for research laboratories”, asserts Mathieu Velve Casquillas, engineer in computer sciences and co-founder of the Elvesys Microfluidic Innovation Center.

The Elveflow OB1 Mk3 encompasses a pressure control range from -1000 mbar to 8 bar. Even when working with multiple dependent channels, the Elveflow pressure controller ensures fast and precise microfluidic flow control which allow researchers to work with a microfluidic device fitting their major concerns. The 0.005 % flow stability provides a superior microfluidic flow control even at low flow rates, to provide quality results and low noise data upon the first time.

Former electro-mechanical pressure controllers had limited gas throughput which limited their capacity to quickly pressurize large tanks. The Elveflow technology enables fast pressurization of tanks up to 1 liter and allow to set up long term or high flow microfluidic experiments.

"With its piezo technology, Elveflow has enabled to multiply performances by 10 and to divide prices by 2 in the sphere of microfluidic research instrumentation», states Mathieu Velve Casquillas.

The Elveflow microfluidic brand has developed patented piezoelectric regulators to set up a microfluidic flow control that is 20 times more precise and 10 times faster than the other flow control devices on the market. Ultra-fast, ultra-stable, easy-to-use and customizable, the Elveflow OB1 Mk3 can be modified to match almost all specific microfluidic requirements.

Each channel of the OB1 Mk3 pressure controller can be associated with a microfluidic flow sensor. Using the Elveflow feedback loop, it is possible to monitor and control flow rate in a microfluidic setup while maintaining stability and responsiveness of pressure driven flows.

The microfluidic device is delivered with the Elveflow software interface, specially designed to allow an easy flow control for researchers’ most complex microfluidic experiments. Thanks to its highly performant optimization, this microfluidic flow controller has been developed to suit most of microfluidic applications including digital microfluidics, cell culture experiments or bead and particle manipulation.
