Rack Screen
The Rack screen is used to select the rack type and collection pattern to be used in
a method (see Figure 18 , Table 11 , and Table 12 ). The default collection pattern is
serpentine; however, it may be changed to collection by row or by column when
collecting in microplates or Titertube tubes. The Divert Between Tubes feature can
be used to reduce the amount of liquid spilled during tube advances. When this
option is turned on (default), the diverter valve switches to waste during tube
advances. However, if this option is turned off (recommended when collecting in
drop mode at low flow rates), the diverter valve switches to Waste only when the
drophead is moving between nonadjacent tubes.
