Valve actuation time
The L-SWITCH™ is a bidirectional 6-port/2-position valve for precise sample injection or switching between different fluids. It is ideal for recirculation in cell culture applications.
Uses minimum bench space
Low internal volume
Peripheral ports (numbered from 1 to 6) can alternatively be connected 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™ can be used as a 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™ series or LineUp™ series it can achieve a highly stable flow with a positive impact on the shear stress.
The L-SWITCH™ 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 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 actuation timing of the valve(s).
