Magnetic particle separation system with flexible bioprocessing container

A magnetic particle separation system, comprising:

• a magnetic field generating device, comprising:
• an upper surface having a receiving area formed thereon;
• and
• a magnetic field generating element disposed beneath the upper surface, the magnetic field generating element being configured to produce a magnetic field above the upper surface;
• and
• a container assembly disposed on the upper surface, the container assembly comprising:
• a flexible container comprising an outer wall having an interior surface that at least partially bounds an internal compartment, the outer wall having a perimeter that encircles the internal compartment, the perimeter including a front side and an opposing back side with the internal compartment being disposed therebetween;
• a fluid inlet extending through the outer wall at the front side, the fluid inlet being in fluid communication with the internal compartment;
• a fluid outlet extending through the outer wall at the front side, the fluid outlet being in fluid communication with the internal compartment;
• and
• a first partition projecting into the internal compartment from the front side between the fluid inlet and the fluid outlet, the first partition being configured such that when a fluid mixture comprising magnetic particles passes from the fluid inlet to the fluid outlet within the internal compartment, the fluid mixture must flow around the first partition.
