OB1 mk3 - MICROFLUIDIC FLOW CONTROL SYSTEM
The new OB1 Mk3 is designed to generate a stable and pulseless flow while remaining extremely reactive. Our microfluidic flow control system enables to control up to 4 channels independently, from -1000 mbar to 8 bar for a wide variety of advanced microfluidic applications.
Elveflow® provides the only microfluidic flow control system in the world to use patented piezoelectric regulators to enable a flow control that is 20 times more precise and 10 times faster than the other flow controllers on the market. You will never be limited by flow control factors in your experiments.

Flow Rate Control & PID
The flow control mode (OB1 + flow sensor) enables to regulate rapidly & precisely the flow rate. With the OB1, you only have to calibrate your flow sensors once and it will function with any chip and any setup. In addition, the consistent speed of our pressure controllers means you no longer have to choose between speed and precision, even when working with multiple dependent channels.
Option & Customization
Choose the number of independent channels from 1 to 4 and mix any combination of pressure range on the same OB1.
Pressure & Vacuum : The OB1 is the only flow control instrument that allows you to control pressure & vacuum on the same channel. For example, this feature enables you to precisely control the position of an object within a microfluidic channel.
Ranges & Colors
200 mbar, 2 bar, 8 bar, -1/+1bar
In-house piezoelectric optimization & calibration (enabling such performances). Challenging bench testing of technical features.
Fully customizable & OEM
The OB1 Mk3 can be modified to fit almost all specific microfluidic requirements. An OEM version is available and can decide to upgrade your system at any time.
Software & SDK
Easy to use & powerful
The OB1 is equipped with the elveflow software full suite, which enables you to control your experiment in one click and to monitor reservoir levels, flow levels and injected volumes. The software also allows you to synchronize the elveflow instruments in your system with a few simple clicks in order to fully automate your setup.
Complex fluidic profiles
Create, monitor and modify in real-time complex pressure and flow rate profiles such as sine, square, triangle, ramp, pulse, or sawtooth…
Complete setup synchronisation
The OB1 Mk3 is equipped with internal & external trigger connectors and can thus be synchronized with any other Elveflow® product, a microscope or any electrical instrument… And enables the synchronization of up to 16 instruments simultaneously.
Flow rate control (optional)
Each channel of your OB1 Mk3 pressure controller 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. The OB1 Mk3 technology enables fast pressurization of tanks up to 1 liter and enables you to set up long term microfluidic experiments.
You can create your own Elveflow® pressure controller using various options:
- Each outlet can be coupled with an additional flow meter.
- Each pressure outlet can be set with a specific maximum pressure range: (200 mbar, 2 bar, 8 bar, -1/+1bar)
- The OB1 Mk3 pressure controller can be prepared with up to 4 independent pressure control units.
New OB1 MK3 : Covers a pressure control range from -1000 mbar to 8 bar.
The following table summarizes the main features of the Elveflow® OB1 Mk3 pressure controller. To provide quality & performance, all of our instruments are tested and calibrated independently (response time, stability, repeatability … ) and all result charts are stored.
(1) Output stability measured at 150 mBar with an external high accuracy pressure sensor (Druck DPI150)
(2) Depending on user computer operating system
(3) Volume dependent – Measurement done on 12 mL tank for a set point from 0 to 200 mbar
According to Elveflow® product code convention, «OB1 Mk3 200» stands for an Elveflow® pressure controller consisting of 4 units with 200 mbar of maximal output pressure. «OB1 Mk3 Mix» means an Elveflow® pressure controller with mixed output pressures. Due to the physical compliance of fluidic systems, performances can change from one setup to another.
