A modular cell culture system includes a standalone cell culture subunit with an interior cavity to house a cell culture substrate in a cell culture space, a radial flow manifold below the cell culture space, a fluid inlet to supply fluid to a center of the manifold, and a fluid outlet to remove fluid from the cavity. The cavity is arranged for fluid to flow in from the fluid inlet, then through manifold, then through the cell culture space, and then out through the fluid outlet. The subunit further includes an alignment feature on at least one of a top and a bottom of the standalone cell culture subunit. The manifold can supply fluid at a uniform rate across a width of the cell culture space, and the alignment feature aligns with an alignment feature of another standalone cell culture subunit, such that multiple standalone cell culture subunits are stackable.

A method of transferring a liquid between multiple containers in cell culture. A first container of multiple culture containers each having a port for transferring content, a three-way stopcock and a medium supply container having one port are connected by a tube, and one pump is arranged therebetween; when the number of containers in the multiple culture containers is two, the three-way stopcock and a second culture container are connected by a tube; when the number is three or more, a three-way stopcock is newly provided between the immediately connected culture container and the three-way stopcock, and connection of the newly provided three-way stopcock and a subsequent culture container by a tube is repeated, whereby all culture containers are connected to the three-way stopcock; and the culture medium is transferred from the medium supply container to each container in the multiple culture containers via the three-way stopcock by the pump.

The present invention relates to smart tank for a bio-pharma process line, a smart tank assembly, a method for assembling a smart tank and a system comprising multiple smart tanks. The smart tank comprises a top plate element, at least one sidewall element, and a bottom plate element, wherein the top plate element, the at least one sidewall element and the bottom plate element are arranged to form a reservoir for receiving at least one biochemical medium. The smart tank comprises further at least one channel, for guiding the at least one biochemical medium and/or an operating medium.

A device for homogenizing a multicomponent fluid including a main channel, a first and a second buffer channels, a collector connected to the main channel with a main conduct, to the first buffer channel with a first fiber and to the second buffer channel with a second fiber. The collector further includes a flow separation point aimed at dividing the main conduct into the first and second fibers, a pumping unit configured to move the multicomponent fluid from the main channel to the first or the second buffer channels through the collector and move the multicomponent fluid from the first or the second buffer channels to the main channel through the collector.

A microfluidic device for cell culture and screening, including a covering element with a plurality of openings configured for introducing and collecting fluids, and a central through hole; an intermediate element with a plurality of microchannels, a plurality of supply tanks and at least one waste tank, and a blind bottom cavity; a lower element, with a collecting tank and a recessed central portion; and a slide housed in a housing pocket. The intermediate element is interposed between the covering element and the lower element to form an upper optical window and at least one culture chamber. The plurality of microchannels puts in fluid communication the plurality of supply tanks, the at least one culture chamber and the waste tank.

A flow path cassette includes superimposed first and second flexible sheets, where a plurality of flow paths are disposed therebetween and detection channel portions are disposed at one or more points along one or more of the plurality the flow paths. Each of the detection channel portions includes a first bulging portion and an opposing second bulging portion. A plate member is aligned with the second bulging portion, and a deformation preventative member is aligned with the first bulging portion. The plate member may move with the second bulging portion, while the deformation preventative member prevents deformation of the first bulging portion.

A bioreactor for culturing of cells is described. Screens suitable as a cell growth scaffold may comprise crossed fibers. Screens may be contained loosely in a screen holder, which in turn may be contained inside a manifold assembly. A lower manifold, screen holder and upper manifold may have identical or similar interior open cross-sections. Flow of liquid medium can occur upwardly through the array of screens, then flowing over a weir in the presence of an air pocket, and into a moat and a pump. The screen holder may have slots whose exterior-facing ligaments are rounded, and may have grooves whose interior-facing edges are rounded. These components may be located inside an incubator suitable to maintain desired environmental conditions and cleanliness.

A method for separating a suspension includes dispensing a liquid suspension into a compartment of a first bag assembly. The first bag assembly is then rotated using a centrifuge so as to at least partially separate the suspension, the first bag assembly being disposed within a first insert that is housed within a first cavity of a rotor of the centrifuge, the first insert having an annular lip portion that freely projects out of the first cavity of the rotor by a distance of at least 1 cm.

A system for processing biological particles including bioprocessing microfluidic devices, reservoirs, buffer tanks and two fluidic connection systems. A first fluidic connection system includes valves and connecting elements between valves, so that each reservoir or port configured to connect a reservoir may be in fluidic connection with each buffer tank, and a second fluidic connection system includes valves and connecting elements between valves, so that each bioprocessing microfluidic device may be in fluidic connection with each buffer tank.
