separated from each other. The peripheral partition walls and
the baffle ridges force a zigzag motion for the flowing liquid.
There are two collection chambers, one above and one below the
separation volume; the light phase is discharged from the upper
collection chamber, whereas the heavy phase is discharged from
the lower chamber. Different types of pump wheels are used for
discharge. The centrifuge was constructed of pure titanium
(later models have the titanium pacified with palladium that has
been diffused into the titanium surface) and was driven by a
pneumatic motor or a variable-speed induction motor. The central
bowl volume was 120 mL, and the holdup time was about 3 s. The
system gave excellent phase separation. Figure 29.Sketch of the
