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, valves 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).

Elveflow software compatibility

Do I have to pay an extra charge to obtain the ESI?

Absolutely not, the ESI is free of charge with unlimited access. The software comes on a USB key with any instrument and can be download on this website.

Can I have access to the ESI's latest version?

New versions are released on a regular basis, they propose new and improved features.

Good news, they are free of charge and can be downloaded directly from this page. You can also ask our support team (customer@elveflow.com) for it.

Can I use the ESI in Mac or Linux environment?

Unfortunately no, the ESI is only compatible with Windows.

Is it compulsory to use the ESI to control Elveflow instruments and sensors?

Absolutely not, free SDK librairies and documented code examples (in C++, Labview, Matlab and Python) are also available to control Elveflow instruments and sensors from your own code or software.

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
OB1 flow controller user

Use trigger signals for advanced synchronisation

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 e.g. experiments with microscope illumination and flow control.

Learn more in this this application review done in collaboration with the Biozentrum Imaging core facility at the University of Basel, and Olympus France.

Workflow automation: a step-by-step example

1. Setup example

The OB1 flow controller with a single 0-2000 mbar channel
A gas splitter to apply pressure onto 4 independant reservoirs
A rotary valve allowing the injection of up to 12 different liquids (4 in this example)
A downstream flow sensor to accurately measure the flow rate and power up the OB1 pressure regulator into a flow controller using a precise, responsive, and stable flow rate feedback loop control.

2. User requirement

I want to perform the following sequence:

inject solution 1 (red) at 5µl/min during 25 minutes to provide buffer to my cells

switch to medium 2 (blue) containing my molecule of interest while keeping the same flow rate for 2 minutes

switch to molecule 2 (yellow) containing a second molecule of interest still under continuous 5µl/min perfusion for 2 minutes

perform a final washing step using medium 4 (green) and increase flow rate to 15µl/min

perform this sequence three times
