There's a few things it would be useful to know - expected volumes, for a
start. How critical will dissolved oxygen be? Most of the automative reading
apparatus we had in the past could only manage a very sedate shaking rate,
which meant that oxygen was frequently limiting as the cultures matured...
Some years back, I was fortunate to use a spectrophotometer at the Free
University of Amsterdam which had been adapted to take a full-sized
continuous culture system (it was used for measuring cytochromes oxidation
levels at steady state) - 1 litre pot and all. I have an idea that they did
the adaptions themselves, but I'll try and check - that particular Prof has
