The present application disclosed a cell centrifugation apparatus and a cell centrifugation, washing and culture method. The cell centrifugation apparatus comprises a centrifuge chamber (1) and a liquid pushing plate (2); the centrifuge chamber (1) has a rotation axis, and the centrifuge chamber (1) is used to connected with a rotation drive mechanism (4) and rotate around its rotation axis under drive of the rotation drive mechanism (4), so as to centrifuge a blood sample contained in the centrifuge chamber (1); and one or more liquid pushing plates (2) are arranged in the centrifuge chamber (1), when the centrifuge chamber (1) rotates, the liquid pushing plate (2) is used to push the blood sample to rotate synchronously along the same rotation direction as the centrifuge chamber (1).

A bioreactor includes a flexible container and an impeller assembly having a hollow tube. The impeller assembly is coupled to the flexible container. At least one mixing element is removably disposed on the hollow tube. A drive shaft is adapted to engage the hollow tube of the impeller assembly and facilitate rotational movement of the hollow tube.

Provided is an expandable, modular tower planter having an internal vertical composting capability, and a method of assembling and using the same. Provided in various example embodiments is a modular composting garden container system comprising a base and a plurality of stackable rings forming a tower upon the base, including an optional base ring specially sized, shaped, and positioned to connect the tower to the base. A plurality of perforated, stackable tube sections are provided that are removably assembled into a compost tube assembly of selectable height and mounted within the interior of the tower and above the base. A plurality of holding struts are sized, shaped, and positioned to removably connect the compost tube assembly with the tower and to securely locate the compost tube assembly relative to the tower. Means are provided for recovering nutrient-rich drainage and selective recovery of compost material for reintroduction into the system.

A fluid mixing system includes a flexible bag having an interior surface bounding a compartment. An elongated first tubular connector is disposed within the compartment of the flexible bag, the first tubular connector having a first end and an opposing second end, the first end of the first tubular connector being coupled with the flexible bag. An elongated second tubular connector is disposed within the compartment of the flexible bag, the second tubular connector being more rigid than the first tubular connector and having a first end coupled to the second end of the first tubular connector. A plurality of impeller are disposed on the elongated second tubular connector at spaced apart locations.

The present disclosure provides a fluid delivery consumable for delivering a fluid dose to a bioreactor. The fluid delivery consumable includes a vial for holding the fluid dose, a plunger, and a connector. The vial includes an outlet and an open end opposite to the outlet. The plunger is engaged with the open end and operable to urge the fluid dose toward the outlet. The connector is proximal to the outlet and attachable to the bioreactor. The connector is adapted to transfer the fluid dose from the vial to the bioreactor when the plunger is operated to urge the fluid dose out of the outlet of the vial.
