Abstract

A liquid bearing for use in rotary devices processing biological fluids is disclosed. The device has a stationary housing and a rotating cartridge. One end of the cartridge is rotatably connected to the housing. The other end is not directly connected to the housing, and, thus, is free to move laterally during rotation. The liquid bearing tends to recenter the free end of the cartridge during rotation.
