A priming subsystem of a cell processing system carries out a method for priming a spinning membrane separator having an inlet and first and second outlets. The method includes opening a first selectable junction disposed between a priming fluid container and the inlet to open a path between the priming fluid container and the inlet, operating a first pump coupled to the first outlet to draw priming fluid from the priming fluid container into the spinning membrane separator, and closing the first selectable junction and a second selectable junction coupled to the second outlet after drawing the priming fluid into the spinning membrane separator. The method further includes operating the first pump after the first selectable junction is closed to draw a vacuum, and opening the first selectable junction after drawing the vacuum.

Spinning membrane separator priming systems and methods

A fluid processing system includes a disposable fluid circuit and reusable hardware configured to accept the disposable fluid circuit. The disposable fluid circuit includes a spinning membrane separator, first and second syringes, and a flow control cassette. The reusable hardware includes a spinning membrane separator drive coupled to the spinning membrane separator, first and second syringe pumps coupled to the first and second syringes respectively, a control cassette interface coupled to the flow control cassette, and at least one controller coupled to the spinning membrane separator drive, the first and second syringe pumps, and the control cassette interface. The controller is configured to selectively operate the drive, the first and second syringe pumps, and the interface to provide a procedure according to a protocol.
