Multiple fluid switching pack

This pack includes all the necessary elements to sequentially inject up to 12 (or more on request) solutions in a fully automated fashion using our computer-controlled 12 to 1 MUX Distribution bidirectional valve, high accuracy OB1 flow controller, and intuitive ESI control software.

A large flow rate range (from 7 nL/min to 30+ mL/min) and volumes (100 µL to up to several Liters) are accessible with this system.

The typical Sequential fluid injection pack setup uses only one single pressure channel to sequentially flow multiple solutions into your microfluidic system. Medium change can then easily be carried out using the MUX Distribution‘s rotary valve that acts as a liquid selector and allows fast switching and selection between your solutions.

In combination with an MFS or BFS flow sensors, the OB1 flow controller allows an extremely stable liquid perfusion (down to 0.006% of the flow rate).

All these operations can be performed using the ESI software interface. The software allows you to fine-tune the flow parameters as well as to automate your experiment using our intuitive scheduler.

Advantages

• A large number of samples: Possibility to sequentially inject up to 12 (or more) solutions in your system
• Stable & pulseless flow rate: Very stable fluid delivery for most accurate results thanks to our pressure-driven flow controller
• High versatility: Use it with any fluidic system such as microfluidic chip, sensor test rigs, flow chemistry setup
• Perform fast switches between media: Switching time below 150 ms
• For small and large volume for long term experiments: Work with volumes from few µL to several liters
• Control both pressure & flow rate: For maximum versatility on your fluid injection
• A broad range of flow rates accessible: From 7nL/min to 30+ mL/min with an accuracy down to 0,2%
• Design flow injection sequences: Create complex patterns and fully automatize your system to test any working conditions over hours or days
• High parallelization possibilities: Test multiple devices with one setup
• Software development kits: in C, LabView, Matlab, and Python for integration into your platform.
