Is it possible to implement a mix of Chemostat and Turbidostat?

For some reason I can’t see the message here but I believe it says:

Hi there,

we would like to implement an hybrid experiment, in which the culture is diluted at fixed intervals (i.e. a chemostat), but with a ceiling for the OD (i.e. a turbidostat). Both functionalities exist already in the software, but currently is not possible to set both so that they work from the same pump (i.e. pump1). Would it work if I moved the RegulateOD function call into one of the custom programs? Or would the two modalities interact in unpredictable ways?

Thanks a lot,
Marco

In answer to this – yes, it sounds like a sensible solution. Turn on the pumps to do chemostat and have a logic check in a custom function which activatres RegulateOD depending on whatever conditions you require (and then turns it off when these conditions are not being violated)

Hi Harrison, thanks a lot for the quick reply; I think the forum has something off, all the first posts are hidden now for some reason.

Anyway, regarding this issue, do you foresee any problem if our custom program was just composed of a single line “RegulateOD(M)”? I am mostly worried about weird interactions between the chemostat and this custom program.

Thanks
