Concept
This project is a collaboration between Univalle (Universidad Del Valle - Colombia) and EPFL (Polytechnical school of Lausanne - Switzerland). The goal was to build an Open Source Bioreactor that everyone could assemble and use, from their backyard to the universities around the world.
This Bioreactor can be used for many applications, such as growing bacterias in anaerobic conditions, with an automatised interface. The temperature, pH, conductometry, feeding and flow of gas going in the reactor can be controlled. All the parameters are stored in a card for future use and can be changed or viewed remotely.
Once the Bioreactor is build, all you have to do is choose the conditions of your experiment (pH, temperature, time of sedimentation, flow of gas), and the Bioreactor will do the rest for you !

pH regulation and conductometry
The Bioreactor contains a pH board, that can be used with a standard gel probe containing reference electrode and a BNC/RCA (Cinch) 2-Wires output. You can choose to regulate or not the pH of your solution, by changing the pH state. In order to regulate the pH, the target pH should be set and solutions of acid and base should be prepared.
Another board is dedicated for the measure of the conductometry.
Dynamic gas Mix
The Anemometer board addresses the need to control the bioreactor atmosphere. It dispose of 4 flow measurement channels to dynamically analyze the input and output flows of gas in the reactor. It allows to obtain a desired mix out gas bottles with pure content (CH4, N2, CO2,...) and potentially to operate the system in anaerobic conditions by ensuring a constant overpressure. Though it, of course, requires a bit more of material both electronic and fluidic.
