Hey there, I was wondering about how to add the 2nd set of pumps to the turbiduistat experiment. Specifically: Pumpset one: “Normal medium in-pump” (As for the normal experiment) Pumpset two: “Normal out-pump” - I wan…

Hi there! I’m running a turbidostat experiment with an OD range between 0.3 and 0.4. Lately, some of the vials diluted below 0.25 on most of the dilution points, as you can see in the example image. I investigated th…

Hi, I’ve been running an experiment for ~850 hours, and for the last ~100 hours about half of the vials stopped back-diluting. I had not touched the machine for over 50 hours at that point. I’ve turned off-and-on the …

I ran a longer multi-day experiment and most of the vials preformed well, but something strange happened with vial 15 right after the 24 hour mark. All vials run with LB + Tween20 0.5% (v/v) and different concentrations…

I’ve been having a similar issue in a couple different contexts. My periods of growth in between dilution events are not very exponential. They seem kind of… sigmoidal? (img below) Any one have ideas/experience/solution…
