Abstract
A centrifugal filtration apparatus includes a containment chamber having a top closure. A perforated barrel is mounted for high speed rotation within the containment chamber. A
filter is mounted to sidewalls within an interior cavity of the barrel. The top closure of the containment chamber can be raised to provide access to the barrel for the purpose of changing the filter.
filter is mounted to sidewalls within an interior cavity of the barrel. The top closure of the containment chamber can be raised to provide access to the barrel for the purpose of changing the filter.
