Features & Benefits
Mux wire: Microfluidic valve controller
The MUX Wire version 3 (V3) microfluidic valve controller works perfectly with all of Elveflow’s microfluidic valves and devices through the same software interface.
It is equipped with internal and external trigger connectors that synchronize it with the other equipment in the setup, such as microscopes or analytical instruments.
The LED indicator on the microfluidic valve controller displays each valve’s type and status, facilitating the use, visualization, and control of all the valves in your setup.
Smart valveS
Smart valves can be independently or simultaneously controlled through Elveflow’s software interface (ESI). The ESI automatically detects these valves once plugged into the Mux Wire.
Three microfluidic valve models are available. The valve model relates to the supported pressure – high pressure (until 6 bars), low pressure (until 3 bars), and low volume (for low internal volume requirements).
The valve type indicates the flow path and the normally open (NO) or closed (NC) state of the valve. The V3 range offers three types of valves: 2/2 NO, 2/2 NC, and 3/2 valves.
The combination of valve models and valve types gives different possibilities to fulfill specific setup requirements.

Elveflow’s smart valves have been carefully selected for their convenience and performance to suit most microfluidic applications. Our valves provide 20ms or less switching time, low internal volume, high chemical compatibility, and no disruption flow.
It is possible to power the MUX wire, plug valves, and control them manually via the push button on the valve. This way, the system works in a standalone mode, without the ESI or a computer!
The 3/2 way valve is ideal for bidirectional control: it can be used to choose between two inlets and one outlet or one inlet and two outlets.

ESI is Elveflow’s advanced software interface that is built to make every experimenter’s life better. It is perfectly adapted from simple setups to very advanced setups and workflow automation. It integrates several modules that make time-consuming and painful tasks very simple. Elveflow also provides Software Development Kit (SDK) libraries to integrate Elveflow systems using your own code.
Some additional features are available when connecting the MUX to the ESI. The new ESI MUX interface offers detailed information about the type and state of the valves connected to the instrument.
Each valve displays:
- the corresponding connected channel number.
- the valve type (2/2 NO, 2/2 NC, or 3/2)
- the valve state (open, closed, way 1, or way2)
The smart valves are automatically added once connected to the MUX Wire. A custom valve or an older valve will not be automatically recognized, you will have to add it manually in the software.
The MUX wire V3 allows you to activate your valves in two ways:
- using the Switch function in the ESI MUX Wire V3 interface
- manually with the push button on the top of the smart valve
Automate your experiment and switch from one configuration to another through the ESI Sequencer:
