Patent ID: 8070354

Claim:
A system for mixing a bioprocessing fluid comprising: a container receiving the bioprocessing fluid; a support member supporting said container in an interior of a housing; a first channel bounded by a first stationary arm and a second stationary arm, said first channel receiving said container; a second channel bounded by a third stationary arm and a fourth stationary arm and, said second channel configured to receive a second container; a first mixing arm and a second mixing arm located in said interior, said first mixing arm connected to said second mixing arm by a connecting member, said first mixing arm located in said first channel and said second mixing arm located in said second channel; said connecting member movable to cause said first mixing arm to move toward said first stationary arm to contact a first outer surface of said container to cause mixing of the bioprocessing fluid and to cause said first mixing arm to move toward said second stationary arm to inhibit contact between said first mixing arm and said first outer surface; and said second mixing arm moving toward said third stationary arm when said first mixing arm moves toward said first stationary arm and said second mixing arm moving toward said fourth stationary arm when said first mixing arm moves toward said second stationary arm.
