The L-Switch™ is a bidirectional 6-port / 2 position valve for injection or switching different fluids. It’s configuration make it ideal for recirculation in cell culture.
The L-SWITCH™ is a 6-port / 2-position injection valve: Peripheral ports (numbered from 1 to 6) can alternatively be connected the right or the left neighbor.
The L-SWITCH™ is actuated by a motor that drives a rotor – where the fluidic path is engraved – against a stator – hosting the fluidic ports.

Bidirectionalflow in the L-SWITCH™
The ESS™ L-SWITCH™ can be used as a useful cell culture tool: a small volume of buffer can be recirculated within a closed loop into the chip for several hours or days. Combined with our MFCS™-EZ it can achieve a highly stable flow with a positive impact on the shear stress.
The ESS™ L-SWITCH™ valve enables you 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 then inject it (using a sample loop).
Several sample loops are available from 5 µL to 100 µL.

The ESS™ Control allows to visualize and control the L-SWITCH and other Fluigent valves position in real time. We have also developed many features to simplify routine experiments :
• Ability to record and log the positions of all devices during the experiment.
• Save a set of parameters as a configuration/method.
• Modular display of your devices: the main window can be contracted and expanded.
• Every control can be undocked and displayed in an individual and repositionable compact window.
• Customize the interface, such to include switch names and fluidic ports for ease of identification.
The Microfluidic Automation Tool (MAT) is an unique program for developing and running time-based experiments. Its drag and drop interface ensure an easy and rapid protocol creation. It allows Fluigent valve control and thier integration with other microfluidic devices. Combine any ESS platform device with MAT for:
• Benefiting from MAT functions such as repeat, if, wait until, … for the development of complex protocols
• Loading and saving protocols.
• Integrating any Fluigent instrument or other devices (requires TLL signal) in joint process.
We work daily to create the next generation of in vitro culture platforms.
