Bio-Rad BioLogic Mixers User Manual

The Maximizer mixer is for use with the Maximizer valve system. The Maximizer Mixer improves
gradient quality by mixing the output of the BioLogic DuoFlow workstation pumps. The mixer may be
used with one of two mixer barrels, which fit between the mixer body and the mixer top and are used
for higher flow rates. The mixer assembly comes pre-assembled with a 5 ml barrel extender, as shown
in Figure 1. This kit includes four screws (1/4-20 x 1/2”) to be used if the 5 ml mixer barrel is removed.
Refer to the following table when selecting a mixer volume.

I. Connecting the Mixer to the BioLogic DuoFlow system.

a. Attach the mixer to a suitable position on a vertical or horizontal bar using its rod clamp. Attach the

mixer to the rack so that the outlet port faces up.

b. Connect the mixer signal cable (mini-DIN connector) to the connector marked “Mixer” on the rear

of the Maximizer.

c. Plug the unused input port using the plug provided for this purpose.

II. Adding or removing a mixer barrel.

Be sure to follow these directions carefully. If the mixer is assembled incorrectly, or if an o-ring is
not correctly placed in the o-ring groove, the mixer will leak.

1. Use the hex key provided (or any 3/16” hex key) to remove the four screws from the top of the
mixer.

2. Remove the mixer top and turn it upside down to remove the o-ring. If the o-ring does not easily
dislodge, use your fingers to remove it.

3. Refer to Figure 2 for re-assembling the mixer. Make sure that the magnetic stir bar lies flat and that
the o-ring groove in either the mixer body or the mixer extender barrel faces up.

4. Place an o-ring in each o-ring groove. If you are using only the mixer body (750 µl), then only one
o-ring is required. If either the standard mixer barrel or the barrel extender is used, then two
o-rings are required.
