Elveflow Smart Interface (ESI)

Elveflow microfluidic software and SDK

Intuitive, powerful, and versatile control of Elveflow instruments

One software for all instruments

Control all instruments through the same interface

User-friendly

Get started within seconds

Workflow automation

Automate long and complex protocols thanks to our powerful scheduler

Easy software integration

C++, MATLAB, Python and LabVIEW libraries available

Features & Benefits

One software for all instruments

The ESI can control up to 16 Instruments ( OB1 pressure controller , flow rate and pressure sensors , sets of valves and valves controller ) via the same interface.

Thanks to the TTL triggers, you can synchronize your Elveflow® system with any other instrument in your laboratory (from microscopes to any electrical instrument, and more).

Intuitive interface

ESI Elveflow Software Interface, one software to control all Elveflow's instruments

The intuitive interface of the ESI microfluidic software facilitates navigation from one instrument to another. Start from simple setups and add instruments (valves, sensors, etc.) through the same interface. Even the most complicated setups can be controlled in just a few clicks!

A Play/Pause button allows changing pressure and flow channels, maintaining the current state of the controller while simultaneously adapting the system to the new settings.

Workflow automation

Built-in scheduler

The scheduler is a user-friendly tool that automates complex steps of your experiments and protocols.

Gain precious experimental time by:

creating or editing instrument configurations (pressure or flow rate profiles, valve positions, etc.)
“dragging and dropping” each step to sequentially arrange them
controlling steps timing
building a complex sequence with loops (for) and conditions (if)
integrating your setup to a wider experimental environment using trigger signals (IN and/or OUT)
saving important data
using the play/pause button to create a file and record the progress of your experiment
saving and loading entire experiments.

Advanced Software Development Kit (SDK) control

Our package allows developers to integrate Elveflow systems into their own control programs. Those libraries enable fast & easy integration of our instruments to your lab project.

We provide the following libraries free of charge (with documentation and example codes):

C++ library, Python library, MATLAB library, LabVIEW library

Discover the ESI in video

Thanks to this video, you will learn how to use pressure-driven flow control with the Elveflow Software!

By coupling our pressure controller with one of our flow sensors, you can perform ultra precise and responsive pressure-driven flow control.

You can request a flow rate value in the Elveflow Software and the pressure controller will automatically adjust pressure to reach the requested value thanks to a customizable PID Feedback loop.

Key features

Independent pressure control of each OB1 regulator channel (or flow control when connected to a flow sensor).
Easy addition and control of Elveflow valves, sensors, and accessories.
Real time intuitive Graph functionalities with customizable windows.
Create configurations to save and recall instrument settings and easily switch from one instrument state to another (works with keyboard shortcuts).
Record any data (.txt files) in a user-defined time interval up to 100Hz. Data are saved continuously to optimize computer active memory for long run experiments.
Visualize your data by generating real-time graph display (pressure, flow rate, etc.).

Testimonials

“After an easy installation, we are now using the OB1 and flow sensors routinely and are very satisfied by both the flow stability and the software's user-friendly interface”
Nelson BC Serre and Matyáš Fendrych, Cell Growth Lab, Department of Experimental Plant Biology, Charles University, Czech Republic
OB1 flow controller and flow sensors user
“We use Elveflow instrument in several projects and they are great to work with. The LabVIEW implementation was also very successful. I hope more people can get to know the OB1 system”
Seongjin Park, Senior Engineer, Illumina

Use trigger signals for advanced synchronization

The Elveflow instruments and the ESI allow in & out TTL signal management. In addition to the centralized control of the entire Elveflow range, combining the workflow automation together with trigger signals allow advanced synchronization of eg experiments with microscope illumination and flow control.
