Valve actuation time
Microfluidic Injection Valve[LSW001]
The L-SWITCH™ is a 6-port/2-position bidirectional microfluidic injection valve used to handle liquids through different valve ports. It is ideal for precise volume injection or for switching between different fluids, as it allows automation of sample injection in your fluid line.
Uses minimum bench space
Low internal volume
Features of Microfluidic Injection Valve
Peripheral ports (numbered from 1 to 6) can alternatively be connected to the right or the left channels. The L-SWITCH™ is actuated by a motor that drives a rotor – where the fluidic path is engraved – against a stator – containing the fluidic paths.
The L-SWITCH™ microfluidic injection valve enables one to load and inject a precise volume of fluid. By selecting the position of the L-SWITCH™ you will choose when you want to load the fluid and then inject it (using a sample loop). Several sample loops are available from 5 µL to 100 µL.
The valve can be controlled by OxyGEN software for long-term experiments. Create a time-based protocol to set the actuation timing of the valve(s).

Discover Fluigent microfluidic valves, a set of compact instruments allowing to complexify and easily handle the fluidic path of your system. Once integrated in the set-up, the valves can be controlled in real-time and even without the requirement of a PC.
How to perform sample injection with the L-SWITCH microfluidic injection valve?
The L-SWITCH is a 6-port / 2-position microfluidic injection valve that, combined with Fluigent’s pressure controllers, allows us to inject a small volume of sample into a liquid stream, reducing cost, as well as to run and automate long-term experiments with high reproducibility and reliability.
The microfluidic injection valve has 6 inputs and two 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.
Example of use
By combining the microfluidic injection valve with our cell encapsulation platform, it is possible to work with samples with a reduced volume (e.g. working with cells of limited availability, such as stem cells, primary cells from patients…). It is also ideal for the use of rare cells or expensive reagents with a total volume lower than 500µl/.
