SEQUENTIAL CENTRIFUGE

摘要

The invention provides a sequential centrifuge for centrifuging discrete samples. Methods of more efficiently centrifuging discrete samples sequentially are also provided. The apparatus and methods for sequentially centrifuging discrete samples provide improved operating efficiencies over conventional batch centrifuges. Such advantages include reducing dwell time, increasing system throughput, reducing sample processing system footprint, and improving precision of the analytical process. The sequential centrifuge further provides the capability of handling critical samples without compromising the operating efficiencies achieved in centrifuging discrete samples in a sequential manner.

1. A method for sequentially centrifuging a plurality of samples comprising the steps of:
providing a centrifuge comprising a drive subsystem, a rotor coupled to the drive subsystem, and at least one sample holder affixed to the rotor, the at least one sample holder having a plurality of sample reservoirs for holding a sample; loading a first sample into a current available sample reservoir; indexing to a next available sample reservoir; accelerating to achieve a preset relative centrifugal force (RCF); maintaining the preset RCF for an amount of time less than the amount of time needed to achieve a desired total FT for the first sample; decelerating to the bring the centrifuge to a stop; repeating the loading and indexing steps for at least one other sample and the accelerating, maintaining, and decelerating steps until the first sample has achieved the desired total FT; and removing the first sample from the centrifuge.
