Running Chi.Bio pumps without Chi.Bio Reactor

[cyanoalgae]

Hi there,
I was wondering whether it was possible to directly run the pumps, without the need for the reactor. I ask this as we need to achieve very low flow rates into a schott bottle and the app.py code has been modified to allow for this. Ideally we would have < 15 schott bottles so ideally we would just buy the pumps separately without the reactor unit to save costs.

Hello

I am afraid no, not really. THe pumps need the power and I2C communications from the reactor, as well as the multiplexer on the main board. It might just about be possible to de-solder some of the connectors from the pumps, add your own 6V supply to the power rails, and then connect pumps directly to the control computer, but this would potentially lead to other issues and be quite difficult to do. If you just need miscellaneous pumping you may be better served getting some off-the-shelf programmable pumps?
