Flow switch : multiple liquids injection and automation

OPTIMIZED SYSTEM DESIGN FOR FULL FLUIDIC EFFICIENCY

Automate the injection of an unlimited number of samples or liquids with virtually no limitation in terms of volumes (µL to L)

FLUIDIC DESIGN EXPERTISE:
Our team of engineers has an extensive expertise in fluidic design. We can advise you on all flow switch systems and related constraints (e.g. avoiding pressure build-up, pressure drops, dead volumes optimization, cross-contamination, flow rate stability…).
Benefit from optimized designs with the most efficient automated flow switch systems.

MICROFLUIDIC ACCESSORIES:
We provide a full solution including all the elements required to put together your automated fluidic system

HIGH QUALITY FLOW SWITCH

Fast flow switch is crucial to maintain a defined flow rate when dealing with multiple liquids.

This requires precise system automation with fast response time, fast switching capabilities and high flow rate stability.

Our pressure-driven flow controllers offer the best response time on the market while our switching valves have been optimized to get the fastest commuting time. 

Lastly, we selected accurate flow sensors to ensure very stable flow rates over time.

High response time (down to 35 ms)
Fast switching valves (down to 156 ms)
Highest stability (down to +/- 0.2 % of the flow rate)
Precise volume dispensing
Wide chemical compatibility to work with any fluids

FLOW SWITCH AUTOMATION AND SOFTWARE INTEGRATION

Benefit from a powerful, modular and automated set-up control solution through the Elveflow Software Interface.

easy control of all Elveflow instruments
quick set-up of injection sequences
simple trigger of external instruments (TTL signals)

OR

Easily communicate with the other components of your system by integrating Elveflow instruments to your own software thanks to our Software Development Kits (C++, MATLAB, Python and LabVIEW libraries available)

AN EXAMPLE OF MICROFLUIDIC CONFIGURATION ALLOWING AN EASY FLOW SWITCH

This fluidic design shows a flow switch between four different liquids using:

a homogeneous split of pressure-driven flow control controlled by a flow controller and a gas-splitter manifold
a 12 inlets to 1 outlet distribution valve where the 4 liquid reservoirs are connected
a standard microdevice
the Elveflow Software Interface control and flow rate readout and control.

This system can also be further tailored to your requirements to work with more than 12 samples or parallelize your systems for instance.
