DESCRIPTION OF BIOLOGIC DUOFLOW SYSTEM SYSTEM OVERVIEW

2.4 MIXERS
Bio-Rad’s DuoFlow mixers improve gradient quality by mixing the output from the DuoFlow Workstation
pumps. There are two PEEK biocompatible mixers for DuoFlow systems.
• MX-1 mixer: A low volume mixer for use with a DuoFlow system not equipped with the Maximizer.
• Maximizer mixer: A large volume mixer for use with the Maximizer.
The mixer cable plugs into the connector labeled Mixer on the rear of the Maximizer or Workstation. If you
will be using the MX-1 mixer, connect it to the Workstation; if you will be using the Maximizer mixer, connect
it to the Maximizer. The mixers have two inlet ports; seal the unused port with the plug provided.
2.4.1 MX-1 Mixer
The Model MX-1 mixer is used when the DuoFlow system is not equipped with the Maximizer. The mixer
may be used with or without a mixer barrel: the mixer body, mixer top, and mixer barrel are provided with the
system; an optional mixer barrel extender is available. The mixer barrels fit between the mixer body and the
mixer top and are used for higher flow rates. Refer to the following table to determine the appropriate mixer
volume.
Table 2-10.
