Abstract: The present disclosure provides a bioreactor for cell processing. The bioreactor comprises a container including a base section comprising a sensor window chosen from a transparent sensor window or a translucent sensor window, a top section arranged opposite to the base section and comprising a fluid inlet and a fluid outlet, and a sidewall extending between the base section and the top section and defining an internal volume of the container adapted to hold a cell suspension. At least one optical element disposed on the sensor window within the internal volume, the at least one optical element adapted to emit a fluorescence signal in response to incident light, the fluorescence signal associated with one or more parameters of the cell suspension.

Abstract: An assembly for handling biological material, including a planar interface having at least one port, and a component retaining element, spaced apart from the planar interface, configured to retain a component for handling biological material, in which at least one component chosen from the planar interface and the component retaining element is moveable to bring the port and the component retaining element into registration with one another. The registration between the at least one port and the component retaining element adapted to form a fluid communication pathway may be provided between a component retained by the component retaining element and a container associated with the planar interface through the port.
