Abstract: A cell culture vessel has a wall and cell culture surface having a plurality of microcavities for culturing cells in three-dimensional conformation, referred to as “spheroids”. The inner surface of the wall and the cell culture surface define a cell culture chamber of the vessel. The wall is attached to the cell culture surface in a way that does not provide flat surfaces on or around the cell culture surface so that the vessel provides an environment suitable for the production of a homogeneous population of three-dimensional cell clusters, or spheroids.

The microcavity substrate comprises a plurality of microcavities, and each microcavity is configured such that cells cultured in the well form a spheroid. The cell culture device may be a reservoir open well microcavity plate used for spheroid cell culture.

Abstract: 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.

Abstract: A cell culture system for culturing cells is provided. The cell culture system including a cell culture vessel with a cell culture chamber for culturing cells, an inlet through which liquid can flow for filling the cell culture vessel, and an outlet through which fluid can exit the cell culture vessel. The system also includes at least one fill sensor arranged to detect liquid within the cell culture vessel reaching a fill level at a predetermined position of the cell culture vessel during filling of the cell culture vessel, where the at least one fill sensor can generate a detection signal when liquid within the cell culture vessel reaches the fill level. Also included is an actuator to change an orientation of the cell culture vessel in response to the detection signal.

Abstract: A cell culture system is provided that includes a cell culture vessel having an interior cavity to house a cell culture substrate in a cell culture space, and at least one port for at least one of fluid inlet to the interior cavity and fluid outlet from the interior cavity. The system further includes a piston having a distal end disposed in the cell culture vessel above the cell culture space, the distal end of the piston being sealed with an airtight seal within the interior cavity. The system also includes a driver coupled to the piston to move the piston so as to increase and decrease a distance between the distal end and the cell culture space. The driver can pressurize the interior cavity via actuation of the piston to harvest cells from the cell culture space through the at least one port.

Abstract: Vial assemblies comprising a tubular body and a flexible bottom or flexible liner are described herein, wherein the flexible bottom or liner is configured to compress at least partially upon the application of force. Methods for storing and removing frozen samples from such vial assemblies are also described herein.

Abstract: A cell culture assembly includes a film defining a plurality of wells extending into the film, where each well of the plurality of wells defines a perimeter extending around the well, the plurality of wells defines an outer perimeter extending around the plurality of wells and extending between the perimeters of adjacent wells of the plurality of wells, and the outer perimeter extending around the plurality of wells defines a wave shape, and a sidewall member coupled to the film, where at least a portion of the sidewall member is oriented transverse to the film, the sidewall member including an engagement portion defining a wave shape that is complementary with the outer perimeter of the plurality of wells.

Abstract: Various implementations of a pipette tip system are disclosed having a number of innovative features. In one implementation, a pipette tip tray includes a support plate and one or more sleeves extending downward from the bottom of the support plate. The sleeves can be configured to increase the stability of pipette tips stored in the tray. In another implementation, a pipette tip rack includes a rack base having one or more support walls extending underneath a pipette tip tray having downward extending sleeves. The thickness of the sidewalls of the sleeves can be reduced in the area of the support walls so that the support walls can reach the bottom of the support plate. In another implementation, a pipette tip rack includes a cover having a cushioning layer on the bottom of the cover that contacts the top of the pipette tips and stabilizes them during handling and transport.

Abstract: A flask assembly that includes: an Erlenmeyer flask; and a liner bag comprising a single opening the bag sized to fit within the flask and having a thickness from about 0.0254 mm to about 0.508 mm. The liner bag is configured for cell culturing and ease of insertion of the bag into the flask. In addition, the liner bag comprises a gas-permeable, polymeric material. Further, the liner bag can include a pocket adapted to receive a removable flask insertion element and/or at least one foldable seam configured to facilitate insertion of the bag into the flask. The liner bag can also include a vent having a gas permeability that is greater than the gas permeability of the gas-permeable, polymeric material employed in the balance of the bag.
