MultiRun Menu for choosing the multiple run function:
Overlay – causes collection to occur in the same tubes for
each subsequent experiment. In this mode, the fraction
collector moves back to the start tube when the end tube is
filled. Stop is used to disengage the experiment.
Seq. Tube+1 – increments the start and end tube numbers at
the end of each run so that one tube is skipped between runs.
In this mode, the initial end tube should be set to reflect the
number of tubes required for each experiment rather than the
number of tubes in the rack. If the incremented start or end
tube number exceeds the rack’s tube capacity, a message
appears stating that there are not enough tubes for the next
run. The start tube and end tube are incremented each time
the fraction collector is disengaged by pressing stop or by
filling the end tube.
Seq. Rack – increments the start and end tube numbers at the
end of each run so that each run starts on a different rack. In
this mode, the initial end tube should be set to reflect the
number of tubes required for each experiment rather than the
total number of tubes available. If the incremented start or end
tube number exceeds the rack’s tube capacity, a message
appears stating that there are not enough tubes for the next
run. The start tube and end tube are incremented each time
the fraction collector is disengaged by pressing stop or by
filling the end tube.
Start Tube #
End Tube #
Used to set the start and end tube. A, B, C, and D correspond
to the rack position. The associated number corresponds to
the tube position within each rack. Start tube and end tube are
automatically updated at the end of an experiment if MultiRun
is Seq. Tube+1 or Seq. Rack.
