15-Channel Millifluidic Multiplexer
The 15-Channel Millifluidic Multiplexer is a programmable valve system that directs fluid flow toward up to 15 individual output channels. It serves as a modular component for precise and flexible fluid distribution in millifluidic systems, such as our Millitransflow Fluidic System.
Designed for use with 1 mm ID / 2 mm OD silicone tubing, the multiplexer employs a single rotary actuator to sequentially open or close flow paths. This approach provides a cost-effective alternative to arrays of independently actuated pinch valves. Although the sequence of channel activation is fixed by the tubing arrangement, this is easily managed through coordinated control of the fluid pump or pressure source, allowing the flow to pause while the desired channel is selected.
Because the valve mechanism does not contact the working fluid, sterile or antiseptic operation is readily achievable. The tubing can be quickly replaced between runs or experiments, supporting use in biological, chemical, and microengineering applications where contamination control and rapid reconfiguration are critical.
