Abstract
A flexible processing and/or expressor chamber for a biological cell processing apparatus is provided which may include a first side and a second side and having a expandable wall, wherein a first end of the expandable wall is attached to a circumference of the first side of the flexible chamber and a second end of the expandable wall is attached to a circumference of the second side of the flexible chamber. Either or both sides of the chamber may include an axial opening.
Claims18
A flexible centrifuge chamber comprising:
- a substantially flexible first side having a centrally located flattened annulus defining an axial opening;
- a substantially flexible second side having a centrally located flattened annulus defining an axial opening;
- and
- an expandable wall, wherein a first end of the expandable wall is attached to a circumference of the first side of the flexible chamber and a second end of the expandable wall is attached to a circumference of the second side of the flexible chamber, wherein the expandable wall comprises an accordion wall having substantially no rigid portions;
- and wherein the chamber is sterilized.
A processing apparatus for a continuous flow centrifuge, comprising:
- a flexible chamber comprising:
- a substantially flexible first side having a centrally located flattened annulus defining an axial opening;
