Abstract
A centrifuge is provided which has a stationary core and a bowl rotatively mounted about the core. The bowl can be configured so that it does not taper inwardly from top to bottom. The bowl has an upwardly extending neck which receives the stationary core. To provide a seal between the core and bowl, a lip seal can be employed which is emplaced about an upwardly extending neck of the bowl and abuts an outwardly and downwardly extending nut formed integrally of the core.
