The MUX Recirculation 6/2 valve is a microfluidic 6-ports / 2-positions valve. The MUX Recirculation 6/2 valve, when combined with the OB1 MKIII+ pressure-driven flow controller, allows to:
- Recirculate a fluid in a closed loop
- Inject small volume samples in a liquid stream
- Run & automate long-term experiments!
- + Experimental versatility with its high bio- & chemical compatibility (PCTFE – PTFE material)
The MUX Recirculation valve has 6 inputs and 2 interchangeable configurations shown on the images below. Each input is connected to a neighbor output, either on the right or the left depending on the configuration.
Main Features & Benefits
- No overpressure Switch between 2 flow configurations in less than 180ms, thanks to the use of a fast & precise valve motor
- Biocompatible High chemical compatibility, PCTFE and PTFE material can be used with organic solvent.
- No waste No dead volume & low carryover volume (0.5µL), for the best solution usage efficiency.
- Easy ¼-28 connection allows for a leak-free operation and quick connection using standard fittings
- Reproducibility & Reliability Perform identical injections over and over

Footnote:
- Volume inside the system from entrance to exit
- Volume of liquid that will be mixed with the next liquid. It is not stuck, but will be swept next time a liquid passes.
- Volume that is stuck in the system (dead end), which is not clearly swept and relies on diffusion to clear out
