Patent ID: 8337755

Claim:
A device for processing biological samples suspected to contain rare target bioentities comprising; a. one or more carriers for receiving and transporting vessels containing said biological samples; b. one or more carriers for receiving and transporting vessels containing reagents; c. one or more vessels containing bulk system fluid; d. one or more fluidic pumping means for manipulating said biological sample and said reagents wherein said pumping means has an aspiration rate between 120 ul/sec to 250 ul/sec to prevent damage to said rare target bioentites linked to paramagnetic particles; e. one or more magnetic separators incorporating a tube rotation system f. at least one magnetic incubator having a 70-degree tripole configuration; and g. one or more programmable controlling means capable of storing and executing commands to control various system components wherein at least one command requires backfluid flushing when aspirating and dispensing said reagents.
