A drying suppression device including: a main body housing a well plate; and an openable/closable lid provided on the main body, the main body including: a holder section that holds the well plate; a liquid storage tank that stores liquid; and a support section that supports the holder while keeping the holder section away from an inner bottom surface of the liquid storage tank, wherein, with the lid being closed, an inner space surrounded by the liquid storage tank and the lid communicate with an outside space.

An assembly includes a single-use sterilizable bag for containing a biological material. The single-use sterilizable bag has at least one insertion opening; and at least one insertable component configured to be inserted into the single-use sterilizable bag via the at least one insertion opening. The at least one insertable component includes a positioning unit for positioning the insertable component with respect to the single-use sterilizable bag and at least one of a processing unit and a sensing unit for handling the biological material.

The present invention relates to an average-density-adjustable structure and more specifically provides a structure the average density of which is adjusted by changing the material of the structure and the size of a void formed therein and which can thereby float on the surface of or in a liquid and can easily bond with or change a material present in a gas or liquid by being equipped with a first material, which is one among an organic catalyst, an inorganic catalyst, a microorganism, and a biomolecule.

Provided is a cell suspension culturing apparatus suitable for large-scale culture of cells, the cell culturing apparatus comprising a culture solution aspirator having a double-tube structure comprising an outer tube and an inner tube inserted in a lumen of the outer tube, and a suspension culture vessel, wherein in the culture solution aspirator, the outer tube comprises a filter through which a culture solution is passed, the inner tube comprises a suction port for the culture solution passed through the filter, and an air hole which communicates the lumen of the outer tube with the outside is disposed distally in a direction of insertion of the outer tube into the suspension culture vessel.

Systems and methods for monitoring and tracking the behavior of cells and tissues in a culturing medium, for example, in a cell culture medium or an in vivo tissue environment, using a tissue scaffold system having one or more sensor arrays. Such monitoring systems include a tissue scaffold system and one or more sensor arrays on the tissue scaffold system in vertically stackable configurations. The sensor array(s) are configured to monitor electrical impedance and/or electrophysiological activities of cells or tissues which may be provided to an external data acquisition system for production of a three-dimensional (3D) map.

The invention relates to a method for the simultaneous heterotrophic and mixotrophic cultivation of microalgae, to a system for the simultaneous heterotrophic and mixotrophic cultivation of microalgae and to the use of the method and/or the system for the cultivation of microalgae.

The invention discloses a bioreactor 10 for cell culture and expansion, comprising a bioreactor chamber 17, a filter 13 disposed within the chamber 17 and at least one tether 14 loosely tethering the filter to the bioreactor chamber. In an embodiment, the tether(s) allow the filter 13 to move from side to side and/or up and down within the chamber 17, preferably without touching an inner surface of the bioreactor chamber 17. Alternatives show, two, three or four tethers, but one or more tethers can be used.

In one embodiment, an algae cultivation system includes a photobioreactor adapted for immersion in growth media contained within the growth media reactor, the photobioreactor including a closed container including multiple panels that together define an interior space in which algae can be cultivated, at least one of the panels being transparent, a porous membrane filter incorporated into one of the panels that enables water, carbon dioxide, and nutrients contained within the growth media to pass into the interior space but prevents contaminants contained within the growth media from passing into the interior space, and a gas control valve incorporated into one of the panels that when open enables photosynthetic gas produced by algae growth within the container to escape but when closed prevents the photosynthetic gas from escaping so as to build pressure within the container that forces water out from the container and dewaters the algae.

Disclosed is a device for exposing an algal solution to light, for a photobioreactor, this exposure device including a flat support including at least one opening capable of holding at least one shaft, the shaft being made of a liquid-tight, translucent or even transparent flexible material, and including an open end capable of holding a sleeve, the sleeve being translucent, or even transparent, and arranged to seal and attach the shaft to the support. The exposure device has positive floatability in water. Also disclosed is a photobioreactor equipped with such a device and a start-up method for such a photobioreactor.
