20080206857 | Device and method for reducing bubble formation in cell culture - A device for minimizing the formation of bubbles or foam in cell culture is disclosed. The device has a manifold which directs the inflow of cells and cell culture media into a cell culture vessel so as to allow for displaced air or gas to vent from the cell culture vessel without mixing with the incoming cell culture media, thereby preventing the mixing of air and cell culture media and minimizing the formation of bubbles or foam inside the cell culture vessel. | 08-28-2008 |
20080299649 | Cell culture apparatus for co-culture of cells - A multilayered cell culture apparatus for the co-culturing of at least two cell types is disclosed. The cell co-culture apparatus is defined as an integral structure having a plurality of cell culture chambers in combination with tracheal space(s). The body of the apparatus has imparted therein gas permeable membranes in combination with tracheal spaces that will allow the free flow of gases between some cell culture chambers and the external environment. In addition, some cell culture chambers may have limited access to air creating relatively lower oxygen content cell culture chambers. The size of the apparatus, and location of an optional neck section, allows for its manipulation by standard automated assay equipment, further making the apparatus amenable to high throughput applications. | 12-04-2008 |
20090191620 | LIMITED ACCESS MULTI-LAYER CELL CULTURE SYSTEM - The present invention provides a multi-layer cell culture device having a rectangular footprint and having multiple cell culture chambers separated by tracheal air spaces, each cell culture chamber having a port and a port cover or an external manifold structured and arranged to allow for transfer of fluid into and out of the cell culture device with reduced risk of contamination, and methods of using the device. | 07-30-2009 |
20090298163 | MULTILAYER CELL CULTURE VESSELS - A multilayered cell culture apparatus for the culturing of cells is disclosed. The cell culture apparatus includes a unitary flask body including a rigid upper and lower surface, connected by side walls. The cell growth apparatus comprises multiple cell growth chambers stacked in vertical alignment and orientation within the unitary flask body. The stacked chambers are held in position by unitary connecting columns that run through each cell growth chamber and terminate at the rigid upper and lower surfaces of the apparatus. The cell growth chambers are separated by tracheal spaces that allow air from the external environment to contact the cell growth surface of each individual cell growth chamber. | 12-03-2009 |
20090298164 | ASSEMBLY OF CELL CULTURE VESSELS - A cell culture apparatus includes a cell culture chamber formed by a first major surface, an opposing second major surface spaced apart from the first major surface, and a first side wall around the first chamber and extending between the first and second major surfaces. A portion of the first sidewall proximate the first major surface comprises an infrared absorbent material, and a portion the first sidewall proximate the second major surface is formed from substantially non-infrared absorbent material. The first major surface is formed by a gas permeable polymeric film that is impermeable to cell culture liquid. | 12-03-2009 |
20090298180 | CELL CULTURE APPARATUS AND METHOD - A cell culture apparatus includes a housing, a bag and an inflatable bladder. The bag is disposed in the housing and has an interior surface defining a chamber for culturing cells. The bladder is disposed in the housing, external to the bag, and is sufficiently inflatable and expandable to exert pressure on the bag when the chamber is substantially free of fluid. The bladder may be inflated and expanded to reduce movement of the bag within the housing. Alternatively, or in addition, the bladder may be inflated and expanded to apply a mechanical stress on cells cultured within the chamber of the bag. | 12-03-2009 |
20100055764 | CELL CULTURE APPARATUS AND METHOD - Cell culture apparatuses and methods for culturing cells include bags for culturing cells. The bags are folded and unfolded to control cell culture conditions. As the bags are folded, segmented sealed chambers for culturing cells are formed. As the bags are unfolded, the segments are unsealed allowing for exchange of fluid between the regions of the subchambers. | 03-04-2010 |
20100112698 | Device for Trapping Extraneous Gas - A device for trapping extraneous gas or bubbles is disclosed. The device is defined as having a gas collection area in a tapered neck portion such that when used as a cell culturing apparatus, extraneous gas or bubbles are trapped and isolated from the cell growth areas where cells or media reside. | 05-06-2010 |
20100119418 | MULTI-WELL PLATE AND METHOD OF MANUFACTURE - A method of manufacture and assembly of multiwell plates employing targeted radiation at an interface in order to achieve bonding is disclosed. The method accommodates glass and polymer attachment as well as polymer to polymer attachment. Resultant plates have unique flatness and optical properties. | 05-13-2010 |
20100190197 | NESTED PERMEABLE SUPPORT DEVICE AND METHOD FOR USING THE NESTED PERMEABLE SUPPORT DEVICE - A nested permeable support device is described herein that can be used to perform various experiments to test new therapeutic compounds (new chemical entities). In one application, the nested permeable support device is used to perform a first pass assay to determine the bioavailability of a new chemical entity following absorption through the digestive tract and metabolism by the liver. | 07-29-2010 |
20100216229 | CELL CULTURE SYSTEM WITH MANIFOLD - A cell culture apparatus includes cell culture units having cell culture chambers, each with at least one manifold. The manifold connects the cell culture unit to a fluid flow channel. The manifold has a dam which allows liquid to pool in the manifold and allows for the creation of an airspace in the manifold, which reduces hydrostatic pressure inside the apparatus and enables the stacking of multiple cell culture units. Embodiments include cascading manifolds, manifolds having reservoirs, and manifolds having valves. | 08-26-2010 |
20100227405 | METHODS OF USING MULTILAYERED CELL CULTURE APPARATUS - A multilayered cell culture apparatus for the culturing of cells is disclosed. The cell culture apparatus is defined as an integral structure having a plurality of cell culture chambers in combination with tracheal space(s). The body of the apparatus has imparted therein gas permeable membranes in combination with tracheal spaces that will allow the free flow of gases between the cell culture chambers and the external environment. The flask body also includes an aperture that will allow access to the cell growth chambers by means of a needle or cannula. The size of the apparatus, and location of an optional neck and cap section, allows for its manipulation by standard automated assay equipment, further making the apparatus ideal for high throughput applications. | 09-09-2010 |
