Bio-Rad BioLogic DuoFlow Pathfinder 80 System DuoFlow Chromatography System Version 4.0 Software New Features - Manual (Page 2)

Version 4.0 software retains the familiar intuitive, accessibility of version 3.0. The ease of
system Setup and method building are retained in the Browser, Setup, Protocol and Run
screens. Manual accessibility to instruments is gained through the Manual screen provid-
ing individual control panels for each instrument and device attached to the system.
Programming has been added to incorporate new instruments and now integrates the
Maximizer buffer blending system with all its peripherals, the BioFrac fraction collector,
new pH Monitor and USB Bitbus Communicator.
USB Bitbus Communicator
Version 4.0 software requires the more robust Windows 2000 operating system and the
new USB to Bitbus Communicator converter box. Any dedicated PC capable of running
Windows 2000 and with a USB connection may be used to run version 4.0 DuoFlow
software programs.
Maximizer Buffer Blending System
• Programming includes support for the Maximizer unit that enables adding automated
buffer blending capabilities to a DuoFlow system. Buffer blending allows users to run
multiple separations, each at a different buffer pH and salt concentration. Four stock
solutions connected to the Maximizer are blended to the correct pH and salt
concentration. Version 4.0 software calculates the acid/base ratio and compensates
for changes in ionic strength and temperature during the run.
• Programming includes support for double the pump flow rate when a Maximizer is in
use. Workstations with F10 pumpheads increase their flow rates to 20 ml/min, F40
pumphead Workstations double to 80 ml/min.
• Programming support incorporates additional valves enabled by adding a Maximizer
to a DuoFlow system. This includes support for 3 additional low pressure solenoid
valves (total of 6 valves), connecting to valve ports (3 on the Workstation and 3 on the
Maximizer. The same is true for high pressure valves enabling a total of 6 high
pressure valves, 3 connecting to the Workstation and 3 connection to the Maximizer.
Additional Maximizer ports include a QuadTec port, a SIM port ( Analog and pH), a
conductivity port , and an auxiliary I/O port .
BioFrac Fraction Collector
Programming support has been added enabling users to incorporate functions of the new
BioFrac Fraction Collector and supporting all 14 new rack and collection schemes of the
BioFrac.
