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.

A system for algae cultivation includes an algae shade having a gas permeable transparent sheet coated with a gas permeable membrane layer. The gas permeable membrane layer is coated on a top side of the gas permeable transparent sheet and a bottom side of the gas permeable transparent sheet respectively, and the gas permeable membrane layer has a thickness of from 1.0 nm to 10,000 nm. A method of cultivating algae using the algae shade is also provided.

A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

The subject invention pertains to a novel gas exchanger system and methods for culturing spheroids, comprising a substrate exhibiting hierarchical high aspect ratio surface features, where the surface geometry incorporates small dimple indentations in the surface and even smaller vent holes or channels that penetrate through the surface, and coated with a superhydrophobic material that forms a contiguous stabilized plastronic air-liquid interface from surface tension that resists the culture medium volume's pressure and guides cells to form spheroids, where the interface serves as an oxygen source and does not slow down nutrient diffusion giving better control over the culture environment.

A cover for a slurry container is provided. The cover includes a plurality of attachable cover units including a first attachable cover unit and a second attachable cover unit. Each of the attachable cover units has at least one edge with an attachable portion. The first attachable cover unit is attached to the second attachable cover unit at the edge of the first and second attachable cover units having the attachable portion.
