HIGHLY EFFICIENT GAS PERMEABLE DEVICES AND METHODS FOR CULTURING CELLS
This invention relates to methods and devices that improve cell culture efficiency. They include the use of gas permeable culture compartments that reduce the use of space while maintaining uniform culture conditions, and are more suitable for automated liquid handling. They include the integration of gas permeable materials into the traditional multiple shelf format to resolve the problem of non-uniform culture conditions. They include culture devices that use surfaces comprised of gas permeable, plasma charged silicone and can integrate traditional attachment surfaces, such as those comprised of traditional tissue culture treated polystyrene. They include culture devices that integrate gas permeable, liquid permeable membranes. A variety of benefits accrue, including more optimal culture conditions during scale up and more efficient use of inventory space, incubator space, and disposal space. Furthermore, labor and contamination risk are reduced.
Cell culture vessel

The substrate includes a plurality of microcavities (220), each microcavity of the plurality of microcavities includes a concave surface defining a well and an opening, the concave surface of each microcavity includes at least one aperture including a dimension less than or equal to about 15 microns defining a path from the well to the second region. A cell culture vessel including a substrate including a plurality of microcavities and a layer of porous material is also provided. Methods of culturing cells in the cell culture vessel are also provided.
BIOREACTOR AND METHOD OF FORMING COMPLEX THREE-DIMENSIONAL TISSUE CONSTRUCTS
A bioreactor and method of forming complex three-dimensional tissue constructs in a single culture chamber. The bioreactor and methods may be used to form multi-phasic tissue constructs having tissue formed from multiple cell types in a single culture chamber. The bioreactor includes at least one translation mechanism to facilitate translation of one or more tissue constructs without direct user intervention, thereby providing a closed, sterile environment for complex tissue fabrication. The bioreactor may be used as a stand-alone device or as part of a large-scale system including many bioreactors. The large-scale system may include a perfusion system to monitor and regulate the tissue culture environment.
Gas Collection Device
The present invention relates to a gas collection device and is directed to a gas collection device for collecting a gas which is generated while microorganisms are cultured in a super absorbent polymer product. The gas collection device may comprise a constant temperature chamber having an interior that is configured to be maintained at a set temperature; a culture flask unit located inside the constant temperature chamber and configured to culture a bacteria therein; an adsorption unit located outside the constant temperature chamber and configured to receive a gas inside the culture flask unit; a pump unit connected to a rear end of the adsorption unit and configured to suck the gas inside the culture flask unit into the adsorption unit; and a mass flow controller located outside the constant temperature chamber and configured to control a flow rate of the gas sucked into the adsorption unit.
CELL CULTURE CONTAINER AND CELL CULTURE SYSTEM
A cell culture container includes: a container body; a cell culture insert having a tubular portion and an oxygen-permeable membrane; and a lid member. The container body is provided with an opening that communicates with an interior of the container body. The tubular portion includes an upper end and a lower end, and is inserted in the opening such that the lower end is located inside the container body. The lower end side of the tubular portion is closed by the membrane. The upper end side of the tubular portion is closed by the lid member. The lid member includes a lower surface that faces toward an interior of the tubular portion. The lid member is provided with an electrode insertion port and a culture medium outlet port that each communicate with the interior of the tubular portion at the lower surface.
Columnar Cell Culture Vessel
A columnar cell culture vessel is disclosed. The columnar cell culture vessel according to an embodiment of the present disclosure may include: a cylindrical body having a chamber disposed therein, an inlet disposed through one side in an axial direction, and an outlet disposed through in the axial direction; a first cap coupled to the inlet and having an inflow port disposed therethrough; a second cap coupled to the outlet and having a discharge port disposed therethrough; and a support which is filled in the chamber and to which cells are attached to be cultured, wherein a culture solution is introduced into the chamber through the inflow port and discharged to the outside of the chamber through the discharge port.
BIOREACTORS CONFIGURED FOR UV STERILIZATION, AND METHODS OF USING UV STERILIZATION IN BIOPROCESSES
In some variations, a UV-sterilizable bioreactor system comprises: a chamber configured to carry out a reaction; a component configured for introducing a gas into the chamber; and one or more UV light sources configured to expose ultraviolet light to surfaces within the chamber. Some variations provide a method of cleaning and sterilizing a bioreactor, comprising: providing a bioreactor system with a chamber to carry out a reaction, a component for introducing a gas into the chamber, and one or more UV light sources to expose ultraviolet light to chamber surfaces; cleaning the chamber; and exposing the chamber to UV radiation to sterilize the chamber. The disclosed technology is a fundamental advance in the field of sparged bioreactors, for many types of commercial fermentations. The bioreactor may incorporate materials that are expressly incompatible with steam sterilization, which allows for the use of lower-cost materials, among many other benefits from UV sterilization.
Massively parallel, multiple-organ perfusion control system
A fluidic cartridge comprises a fluidic disk having a plurality of alignment openings; a fluidic chip comprising a body, one or more channels formed in the body in fluidic communications with input ports and output ports for transferring one or more fluids between the input ports and the output ports, and a plurality of protrusions formed on the body and received in the alignment openings of the fluidic disk for aligning the fluidic chip to the fluidic disk; an actuator operably engaging with the one or more channels for selectively and individually transferring the one or more fluids through the one or more channels from at least one of the input ports to at least one of the output ports at desired flow rates; and a tube member defining a cylindrical housing for accommodating the fluidic disk, the fluidic chip and the actuator therein.
CELL CULTURE VESSELS WITH STABILIZER DEVICES
A cell culture vessel includes a vessel body, support columns, and a stabilizer device. The vessel body defines a cell culture chamber enclosed between a bottom wall and a top wall. The support column is within the cell culture chamber and extends between the top wall and the bottom wall. The stabilizer device covers a width and length of the cell culture chamber and has a column engaging structure that is sized to slidingly engage the support column such that the stabilizer device is movable along the support column as a liquid culture medium is received in the cell culture chamber. The support column guides the stabilizer device along a length of the support column as the stabilizer device rises with rising liquid level in the cell culture chamber during a liquid culture medium filling operation.
