Centrifuge with removable core for scalable centrifugation

摘要

A centrifuge apparatus is provided that operates at certain predetermined parameters depending upon a product to be separated and is useable with a plurality of rotor assemblies. For example, a first rotor assembly of said plurality of rotor assemblies includes a first core having a first core configuration which is contained within a rotor housing of the first rotor assembly to define a first volume capacity such that the product passing through the first rotor assembly having the first volume capacity during rotation of the first rotor assembly in the centrifuge apparatus achieves a first particle separation of the product. A second rotor assembly of said plurality of rotor assemblies includes a second core having a second core configuration which is contained with a rotor housing of the second rotor assembly to define a second volume capacity such that product passing through the second rotor assembly having the second volume capacity during rotation of the second rotor assembly in the centrifuge apparatus achieves a second particle separation of the product. It is observed that the second particle separation is a linear change with respect to the first particle separation.

1. A method for achieving linear scale separation of particles of a product during centrifugation comprising the steps of:
operating a centrifuge apparatus at certain predetermined parameters depending upon a product to be separated; placing a first core having a first core configuration in a rotor housing to define a first rotor assembly having a first volume capacity; rotating the first rotor assembly having the first volume assembly having the first volume capacity in the centrifuge apparatus and passing the product through the first rotor assembly during rotation thereof so as to achieve a first particle separation of the product; substituting a second core having a second core configuration within the rotor housing to define a second rotor assembly having a second volume capacity that is different than the first volume capacity; and rotating the second rotor assembly having the second volume capacity in the centrifuge apparatus and passing the product through the second rotor assembly during rotation thereof so as to achieve a second particle separation of the product which is a linear change with respect to the first particle separation.
