Hello,
We are about to purchase our first set of reactors, but unfortunately the pump set provided by LabMaker is not compatible with the environmental conditions of our lab.
In our experimental setup, we run fermentations in closed environments with a high moisture content (around 70%). Because of this, and to avoid overheating issues, we would like to ask if you could recommend a brushless motor–driven peristaltic pump to substitute them. We would be happy to try assembling our own set of pumps.
Thanks in advance for any help.
Best.

Hello Gaby
Do you have specific experience finding that pumps like this cannot operate in such circumstances? We have had these running in 37 degree hot rooms with high moisture content for some years without major drama. Further, if they DO break you can easily replace them, the pump parts themselves (minus all the control electronics) can be purchased on Alibaba/Aliexpress for <10 USD each. Alas I do not know of specific brushless motor pumps that could be substituted.
