    摘要： A centrifugation system comprises a drive assembly (16), a non-contact seal assembly (30) and a tank assembly (14). The drive assembly has an upper (20) and a lower housing (22) separated by a top bearing plate (24) with a rotor opening (26), and a drive is disposed in the lower housing with a rotor shaft aligned with the rotor opening. The non-contact seal assembly has an upper guard (32) and a skirted pivot (34), and is secured to the top bearing plate at the rotor opening so that the skirted pivot is operatively coupled to the rotor shaft for rotation without contacting the upper guard. The upper guard and the skirted pivot form a labyrinth seal to mitigate leakage of fluid from the upper housing through the rotor opening into the drive in the lower housing. The tank assembly is connectable to the lower housing so that a centrifuge rotor housed therein is rotatably driven by the drive via the skirted pivot.
