Microfluidic Sampling Valve[2SW002]
The 2-SWITCH™ is a compact 3-port/2-way microfluidic sampling valve. Using standard fittings, it can be integrated into any microfluidic setup. Its unique and compact design allows users to combine 2-SWITCH™ devices to save space on your benchtop.

Features of microfluidic sampling valve
Fluid switching & sampling
Fluid switching & sampling
The 2-SWITCH™ can be used for fluid switching or dispensing depending on the direction of flow. When 2 liquids are coming into the valve, select which to deliver to your device. Alternatively, one liquid can be driven into selected parts of a setup for sampling/sorting.
Parallelize & Combine
The specific design of the valve allows one to combine several together with a minimum of space requirement. Added to the automation software, one can easily create multiple fluidic paths.
The valve can be controlled using OxyGEN software for long-term and complex experiments. Create a time-based protocol to set the timing of the valve(s).
The 2-SWITCH™ is a versatile device that is easily adapted into an on/off valve (2-port/2-position) by connecting a plug to one port (other than the common port).
A compact and useful tool
Its versatility makes it ideal for applications where fluid sorting, switching or periodic sampling are required.
Smart control and automation of your fluidic path
The 2-switch microfluidic sampling valve can be combined with other compact instruments to allow easy and precise fluid handling in complex microfluidic systems. Once integrated in the set-up, the valves can be controlled in real-time and don’t require a PC.
Benefits of the 2-switch microfluidic sampling valve
- Ultra-low switching time: less than 3ms, making it compatible with our ultra-fast flow controllers
- Low internal volume: 28µL
- Versatility and ease of use
Examples of use of the 2-switch microfluidic sampling valve
When integrated in our droplet production station, the 2-switch generates highly monodisperse alginate droplets. The switch is used in 2 configurations:
- Fluid switching: In position 1, the switch will select the injection of water to stabilize the system and start droplet production of the desired diameter. Once the droplet generation is stable, switching to position 2 will allow users to alginate droplets
- Fluid sampling: At the outlet of the chip, the switch position will determine if the generated droplets are recovered in the collecting tube or discarded into the waste
During an immunostaining experiment, users need to easily switch from the waste for calibration and system washing steps to the microfluidic chip for reagent injection and washing steps. The 2-switch, combined with our automated system for sequential injection experiments, is an ideal solution to select the flow direction either towards the chip or the waste.

The 2-SWITCH™ is a 3-port / 2-way solenoid valve: two ports can alternatively be connected to a third one (the common port), thanks to the movement of a diaphragm actuated by a solenoid. The flow is bidirectional in the 2-SWITCH™, meaning that the device can be used as a selector and a distributor.
