Re: Amersham bioprocess rig flow deviations: Hi we are having problems with 10mm bioprocess rigs at work. The rigs will not hold a steady flow at 21 and 400 L/hr. An identical rig is able to sustain the exact same flow rates. Has anyone encountered similar problems with these amersham bioprocess rigs? The amersham (ge healthcare) reps claim it is a problem they have not encountered before but i suspect it may be a design fault-possibly electrical. All the trial and error experiments we have run have proved fruitless.
rigless and out of answers!
