On an underside (18) arranged remote from the loading opening (20a), the receptacle (20) has an unloading opening (20b), which can be closed by means of a closure mechanism (38) arranged in the housing (14). The closure mechanism (38) is provided with a slide (40, 42), via which the slide (40, 42) is movable to the unloading opening (20b) to permit closure and is movable from the unloading opening (20b) to an opening position to permit opening.

The invention relates to a method for producing at least one closed region on a carrier surface of a carrier, wherein the method comprises the following steps: a. adding a first fluid comprising at least one cell and/or at least one particle to the carrier surface and b. adding a second fluid, wherein the second fluid is immiscible with the first fluid and at least partially covers the first fluid and c. acquiring at least one item of cell information and/or of at least one item of particle information and d. producing the closed region on the basis of the at least one acquired item of cell information and/or the at least one acquired item of particle information.

A cell sheet-forming member provided with a surface for forming a cell sheet, wherein the surface comprises a plurality of flat parts and a plurality of concavo-convex parts. Each flat part has a shape extending along a first direction and the plurality of the flat parts are aligned along a second direction intersecting with the first direction over the entire surface. Either of convex parts or concave parts have a stepped structure and individual concave and convex parts include a plurality of the stepped structures which fill gaps between flat parts adjacent to each other, wherein the pitch of said stepped structures is from 100 nm to 10 μm inclusive.

A corneal tissue culture system and a corneal tissue culture method for increasing corneal endothelial cell density, healing of damaged corneal endothelial cell, and stimulating corneal endothelial cell proliferation are disclosed. The corneal tissue culture system comprises a tissue culture medium and a tissue culture dish to reduce metabolic pressure and reduce corneal tissue edema.

An automatic processing device of culture plates (2) for microbiological samples, wherein the processing device (1) includes a support frame (3); a slide (4) provided with a seating (5) configured for removably housing a culture plate (2) and movably mounted on the support frame (3) so as to be selectively displaceable between a first loading position, a plurality of image-acquiring positions, and a first unloading; a camera (6) of a linear type, provided with an optic (7) of a telecentric type and a trilinear sensor, and arranged according to a vertical axis (8) such as to acquire, at an image-acquiring zone, a multiplicity of linear images of corresponding linear portions of an upper surface of the culture plate (2), during the displacing of the slide (4); a first lighting device (11) orientated such as to illuminate the linear portions of an upper surface of the culture plate (2); an advancing device (14) of the slide (4) configured such as to enable obtaining a constant and substantially vibration-free advancing speed of the slide (4) in the image-acquiring zone; and an electronic control device (9) of a functioning of the camera (6), of the lighting device and of the advancing device (14).

A method and apparatus for locating and selecting a colony of microorganisms on a culture dish and identifying microorganisms in said selected colony using MALDI. The method comprises the automated steps of locating and selecting a colony of microorganisms on a culture dish; obtaining a sample of said selected colony of microorganisms; depositing at least some of said sample of said selected colony of microorganisms on a target plate; and transferring said target plate with said sample in an apparatus for performing MALDI for identification of said sample of said selected colony of microorganisms. A sample of a colony of microorganisms is automatically deposited on a depositing spot such that the sample covers at most approximately half of said one of the depositing spots of the target plate. A suspension of a sample of microorganisms is automatically prepared by automatically picking the sample with a picking tool and submerging the picking tool with said sample in a suspension, after which the picking tool is vibrated in vertical sense only to release the sample from the picking tool.

A microcavity dish (10) for cultivating cells includes a dish body including a sidewall (16) that encloses a cell culture chamber within the dish body. The dish body has a top and a bottom (12). The bottom includes a cell culturing substrate comprising an array of microcavities (46). The sidewall includes a transition portion (30) that divides the sidewall into an upper portion and a lower portion that is offset inward relative to the upper portion defining a liquid medium delivery surface (26) that extends at least partially along an interior surface (28) of the sidewall and slopes toward the bottom.

The present invention relates to a tissue cell culture device which includes a tissue cell culture body. The porous material used as the tissue cell culture body is a porous metallic material which is formed by pore cavities classified by a pore size of the material and cavity walls surrounding to form the classified pore cavities. The cavity wall surrounding to form an upper level of large pore cavity is provided with a lower level of small pore cavity. The pore cavities in the same level are in communication with each other. The pore cavities in different levels are also in communication with each other. This device is particularly beneficial for cell cultivation and allows tissue cells to grow freely and normally in a three-dimensional space.

The present invention relates to a Petri dish comprising a dish body which comprises a bottom wall and a side wall which extends along an outer circumference of the bottom wall, the bottom wall and the side wall of the dish body form an upper opening space adapted to accommodate cultures; a dish lid adapted to cover the upper opening space from above the dish body, the dish lid comprises a top wall and a side wall which extends along an outer circumference of the top wall, wherein the dish body and the dish lid are two independent members that are detachable, and the side wall of the dish body is formed on the outer side thereof with a ring for gripping that extends circumferentially, and the ring for gripping having an outer diameter larger than that of the dish lid. The Petri dish according to the present invention has a simple structure. Through the ring for gripping on the dish body, the user can easily hold the dish body without accidentally dislodging the dish lid or sliding it off the dish body.
