Abstract:
The present invention provides a roller bottle for cell growth culturing, the roller bottle including a bottom wall; a top wall having an opening formed therethrough; and, a side wall extending between the top and bottom walls, a plurality of corrugations being defined in the side wall. Further, a distance is defined between the top and bottom walls, and the corrugations are selectively deformable to alter the distance. Advantageously, with the present invention, a single roller bottle may be provided with its length being adjustable in response to cell culture size and density.
Abstract:
A disclosure is made of various apparatus and methods for culturing and preserving cells and tissue in ways that minimize contamination potential, direct cells to reside in desired areas, allow uniform cell distribution during seeding, provide optimal growth conditions by controlling the amount of medium residing in proximity of cells, allow desired compounds and molecules to reside in proximity of the cells, allow co-culture, provide for efficient scale up, allow a desired shape of tissue to be created while retaining a closed system, and allow cryopreservation and reconstitution of cell and tissue while retaining a closed system. The apparatus and methods can be combined to prevent the need to remove the tissue from the enclosure at any point during the sterilization, seeding, culturing, cryopreservation, shipping, or restoration process. Also disclosed is an apparatus and method of pipette interface with a container in a manner that blocks contaminants from entering the container.

Abstract:
A device and a method for the cultivation of cells is disclosed that utilizes external pneumatic pressure responsive to liquid level sensors to gently recirculate and cause turbulence in cell growth medium to promote cell growth without any shearing action and without a stir motor or mechanical manipulation means.
Abstract:
A disposable device and method for axenically culturing and harvesting cells and/or tissue in consecutive cycles. The device consists of a sterilisable disposable container which may be partially filled with a suitable sterile biological cell and/or tissue culture medium. The container has means for removing excess air and/or waste gases therefrom, and means for introducing inoculant and/or culture medium and/or additives therein. A reusable harvesting means enables harvesting of at least a portion of the medium containing cells and/or tissue when desired, thereby enabling the device to be used continuously for at least one subsequent consecutive culturing/harvesting cycle. The portion of medium containing cells and/or tissue remaining from a previously harvested cycle may serve as inoculant for a next culture and harvest cycle.
Abstract:
The present invention relates to a photobioreactor for the cultivation of photosynthetic micoorganisms having at least one light bank substantially totally immersible in the liquid microbial culture contained in the photobioreactor so that substantially all of the emitted light is absorbed in the culture. The light bank comprises a plurality of light tubes in substantially close proximity to each other, electrical leads extending from the light tubes to a source of electric power and an enclosure means enclosing at least the portions of the electrical leads into the lead tubes to render such points impervious to the liquid microbial culture. The light bank serves as a light source as well as may be arranged to form channels for the circulation of the liquid culture within the photobioreactor.
Abstract:
A simple and functional apparatus is disclosed for use in the home, field and other places in which water or other fluids can be evaluated for the presence of bacteria. Also disclosed is a convenient tablet reagent for use with liquid peroxide with the apparatus.
Abstract:
A FERMENTOR COMPRISING A NORMALLY HORIZONTAL CYLINDRICAL CHAMBER HAVING CLOSED ENDS AND INCLUDING A PLURALITY OF APERTURED DISCS ROTATABLY MOUNTED IN THE CYLINDER, INLET CONDUITS FOR BIOLOGBICAL NUTRIENTS AND AIR ONE END OF THE CLOSED CYLINDER AND CONDUITS FOR REMOVING AIR, SPENT NUTRIENTS AND BIOLOGICAL PRODUCTS AT THE OTHER END OF THE CYLINDER, THE DISCS BEING ADAPTED FOR CONTINUOUSLY ROTATABLY CARRYING PORTIONS OF LIQUID NUTRIENT FROM THE
BOTTOM OF THE CYLINDER INTO A GAS PHASE AT THE TOP OF THE CYLINDER, IS DISCLOSED.
Abstract:
A photobioreactor system includes a frame, a reflective wall coupled to the frame such that the reflective wall defines and circumferentially surrounds an interior chamber, and multiple light sources coupled to the reflective wall such that the multiple light sources circumferentially surround the interior chamber. The interior chamber is configured to receive a container that holds and supports growth of a desired organism.
Abstract:
Disclosed herein are platforms, systems, and methods including a cell culture system that includes a cell culture container comprising a cell culture, the cell culture receiving input cells, a cell imaging subsystem configured to acquire images of the cell culture, a computing subsystem configured to perform a cell culture process on the cell culture according to the images acquired by the cell imaging subsystem, and a cell editing subsystem configured to edit the cell culture to produce output cell products according to the cell culture process.
