Feature Description
Control module The fraction collector head contains the
display, function keys, and alphanumeric
keypad (see
Chapter 2, Front and Rear Panel
Controls and Connectors , on page 9). Its
height may be adjusted to accommodate tube
heights up to 150 mm.
Base The fraction collector base holds the rack
positioning tray, power switch, and I/O
connectors. It is designed so that it can be
stacked on top of the NGC, BioLogic DuoFlow,
and BioLogic LP chromatography system
workstations if benchspace is limited.
Columns The columns hold the fraction collector head
and serve as a rack for mounting the diverter
valve or other devices, such as a pH probe and
a UV monitor, using Bio-Rad bar clamps
(Cat. #750-0265).
Rack positioning tray Accurate dispensing requires that racks be
positioned using the rack-positioning tray.
Molded indents on the tray allow the rack feet
to be placed securely on the rack-positioning
tray. The tray holds two full racks (F1, F2, or F3)
on one face and can be inverted for positioning
of four half-racks (H1, H2, H3, or H4). See
Chapter 3, System Configuration and
Plumbing
, on page 13 for available rack
options.
Dispenser arm The dispenser arm moves the drophead in a
serpentine motion over each of the collection
tubes. The arm movement can be changed to a
column or row pattern for microplates and
Titertube tubes.
