## Abstract

A system for mixing a bioprocessing fluid includes a container receiving the bioprocessing fluid and a support member supporting the container in an interior of a housing. A first channel is bounded by a first stationary arm and a second stationary arm with the first channel receiving the container. A first mixing arm and a second mixing arm are located in the interior. The first mixing arm is connected to the second mixing arm by a connecting member. The first mixing arm is located in the first channel and the second mixing arm is located in a second channel. The connecting member is movable to cause the first mixing arm to contact a first outer surface of the container to cause mixing of the bioprocessing fluid.
