Valve actuation time
L-SWITCH™
[LSW001]6-port/2-position valve
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.
- Quick
- Compact
Uses minimum bench space
- Biocompatibility
Biologically compatible
- Accurate
Low internal volume
Features
6-port/2-position
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.
Fluid recirculation
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.
Sample injection
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.
Automation
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).
