Thankfully, my local pro lab ... still has a turnaround of four hours for E6...
im based in australia and my E-6 process or runs 12 hours a day 7 days a week with a volume high enough to warrant such a schedule, I have always been led to believe that the E-6 process is one that requires a constant high volume of material to be processed through it or otherwise the stagnation will lead to a higher chance of the chemistry drifting. My machine has never been idle to see this effect. If a machine is only processing 2 days a week does this open the doorway for a whole heap of control issues?
I would love to hear form fellow pro lab owners on this as I have no experience with giving tanked machines down time.

Hi Bob
Thanks so much for the feed back, I agree with your post entirely!
I also agree with the earlier post about checking processes with control
strips and enforce that any good lab should run at least 2 controls a day to see how there process is running.
However on the subject of control strips and monitoring the process it is my guess that a constantly active processor would be a lot more stable than one with down time. And this would be preferable compared to having to check a control strip and spiking the system back to where it needs to be before any clients film is run.
sorry if I seem pedantic I have had it drilled into me that the optimum way of running E-6 is to not keep it idol and with E-6 processing theres no forgiving. Many thanks for the replies.
At least they are still running it and keeping the prices reasonable. AFAIK, there is only one left in the Detroit area that still runs E-6 (last price quote was $2/4x5 sheet). I still run my own, and at least one local shop stocks the E6 5L kits at a lower price than Calumet.

... Every time I get on a thread like this it makes me think back to the days I started Silver Shack a small black and white lab only ...
