Rotary multi-port microfluidic valve for industry
[IVMSW1]Fluigent M-X
The Fluigent MX is a bidirectional 11-port / 10-way microfluidic valve for injection or selection of up to 10 different fluids. The flow is bidirectional in the valve. The device can be used as a selector or as a distributor for either multiplexing or demultiplexing purposes.
Main benefits
Automation- Compact
Easily fits in systems and machines
- Quick
Fast actuation and response time
- Accurate
Low internal volume
Features
11-port/10-position
The Fluigent M-X is an 11-port / 10-position rotary valve. Any of the peripheral ports (numbered from 1 to 10) can be connected to the central channel, and the fluidic path created is bidirectional. The MX is actuated by a motor that drives a rotor. It can also be used with a manifold to use a single pressure pump to deliver multiple liquids.
Sequential injections
Up to 10 liquids can be sequentially delivered. Each step can be automated using Fluigent software.
Automation
The valve can be controlled by our software for long-term experiments. Create a time-based protocol to set actuation timing of the valve(s).
Related applications
Description
Example 1: sequential injection of several fluids
In this application example, up to 10 liquids (4 on the schematic) are selected sequentially to be delivered to the chip by the M-X. The samples at the outlet of the chip may also be sorted by using a bidirectional valve either into a collection tube or to waste. Each step can be automated either by using Fluigent software.
Example 2: Sample generation and collection
In this application example, different concentrations of the molecule of interest are injected into the chip generating water in oil droplets containing various concentrations. The droplets are then sorted at the outlet of the chip using the M-X on their analyze concentrations. Each step can be automated using Fluigent software.

How to add the M-X in my experiment and how to connect it?
To learn how to connect the M-Switch™ on the Switchboard, go to the ESS™ section.
Concerning the tubing connection:
1. Cut the 1/16’’ OD tubing to the desired
length, leaving a square-cut face.
2. Slide the ¼ -28 fitting over the tubing,
with the thread facing outwards. Slip the
ferrule over the tubing, with the tapered
portion of the ferrule facing the fitting.
3. The conectors and ferrules are specifically designed to work together. FLUIGENT
advises you to only use the provided
ferrules together with the provided nuts.
4. Insert the assembly into the receiving
port, and while holding the tubing firmly
against the bottom of the port, tighten
the connector.
5. To check the tightness of your connection, you may pull gently on the tubing
and verify that it remains secure.
How can I clean the M-X after use?
You can clean the M-Switch™ in the same way than the Flow Unit.
Besides, Fluigent strongly advises you to use filtered solutions. Wetted materials are custom PCTFE and UHMW-PE.
How to use tubing with external diameters different from 1/32″?
If one wants to use tubing with external diameters different from 1/32″, a sleeve should be used to adapt to the different size
User case
Context
An established company makes wastewater testing systems using syringe pumps. The system draws samples and reagents from multiple reservoirs. The moving seals on the syringe pump break often and cause device failure and wasted reagent.
Solution
Fluigent proposed a 10 port M switch rotary valve powered by a pressure pump which doesn’t use moving seals.
Result
The Fluigent solution eliminated leakage and decreased overall reagent consumption due to a lower internal volume.
