Embodiments of the present invention may provide fluid flow coordinators, passive flow field modifiers, or even inwardly protruding helical spines which can be used in continuous, scalable, low energy usage, bioreactor systems perhaps to provide optimal mixing of microorganisms with nutrients, gases, or the like or even to move microorganisms, such as algae, in and out of light for effective and optimal growth.

A system and method of growing and harvesting algae provided whereby the system encompasses incubation tanks, internal lighting, chilled air diffusers, and an inline incubation tank for continuous batch processing. A centrifuge separates algae from growth media, and the media is processed through a series of reclamation steps so that cleaned water is reused for fresh media.

A device for storing, incubating or manipulating biological samples, in particular incubating device or shaking device, comprising a sample chamber, an irradiation chamber, and a holder with a UV light source, wherein a sidewall of the irradiation chamber comprises a first mounting member and wherein the holder comprises a second mounting member configured to interact with the first mounting member for pre-mounting the holder to the sidewall.

Embodiments disclosed herein relate to novel flasks, methods and systems employing said novel flasks, and sensors for use within said flasks and systems. In some embodiments, flasks and systems described herein are used to culture cells and/or detect changes in pH levels or dissolved oxygen and/or carbon dioxide levels in a cell culture sample resulting from the growth of living cells contained within a reaction vessel such as a flask. The devices may be used to detect changes in pH and dissolved oxygen levels in a liquid contained in the reaction vessel due to growth of living cells.

A photobioreactor includes one or more annular chambers concentrically positioned about a central axis, and an algae slurry contained within the one or more annular chambers.

A fine particle measurement device includes a support stand (20) that has a groove (F) extending in a predetermined direction and is configured to support in the groove an observation container (10), which has an elongate shape and accommodates a liquid sample containing a fine particle therein such that an extending direction of the groove (F) coincides with a longitudinal direction of the observation container (10); and an imaging unit (40) that is configured to capture an image of the fine particle in the observation container (10) at a position where the support stand is out of a field of view, the observation container (10) being supported by the support stand (20).

An open raceway algae cultivation system includes a channel configured to contain an algae cultivation fluid. The channel includes a contraction zone having a width and a depth and an expansion zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel and includes an entrance and an exit. A width of the contraction zone decreases leading into the entrance of the pump, and a depth of the contraction zone is greater than a depth of at least a portion of the channel located outside of the contraction zone. A bottom of the channel at a beginning of the contraction zone is lower than a bottom of the channel at an outlet of the expansion zone, and the contraction zone increases in depth along at least a portion of its length.

Embodiments of the present invention may provide fluid flow coordinators, passive flow field modifiers, or even inwardly protruding helical spines which can be used in continuous, scalable, low energy usage, bioreactor systems perhaps to provide optimal mixing of microorganisms with nutrients, gases, or the like or even to move microorganisms, such as algae, in and out of light for effective and optimal growth.

A photoreactor for cell assay and array chemical and biochemical reactions has a reaction chamber, an input aperture, and a lamp. A specimen receptacle with a reflective surface is positioned within the reaction chamber. The lamp has a light source, a temperature control system, and a lens. The light source is mounted onto the temperature control system and the lens is mounted onto the temperature control system. Accordingly, the temperature control system is able to moderate the temperature of the light source and the reaction chamber. The input aperture is an inlet that enables the lamp to be mounted onto the reaction chamber and retained in optical communication with the specimen receptacle. The positioning of the input aperture enables the light from the light source to be evenly distributed across an exterior surface of a specimen placed within the specimen receptacle.

The present disclosure provides methods and materials for the cultivation and/or propagation of a photosynthetic organism. Such methods may comprise the use of a lamp assembly that comprises a plurality of circuit boards, each comprising at least three edges, arranged in a substantially spherical shape defining an interior lamp assembly volume, wherein the plurality of circuit boards comprise a first planar surface in contact with the interior lamp assembly volume and an opposing second planar surface comprising light emitting diodes (LEDs); and a barrier that surrounds the plurality of circuit boards forming the substantially spherical shape.
