Abstract
A centrifuge having an automatic dispensing rotor is employed for pelleting material and automatically decanting supernatant liquid by means of gravity drainage. The automatic decanting rotor employs a magnetically activated lock mechanism for locking swinging buckets in an elevated position while the rotor is at speed. When the rotor is brought to rest, the swinging buckets do not pivot to their rest position but are sustained in their elevated position by means of the magnetically activated lock. Liquids are automatically decanted from the swinging buckets when the rotor is brought to rest while the swinging buckets are sustained within their elevated position.
