Abstract
Provided is a culture plate having a plurality of accommodating parts for culturing cells, said culture plate comprising a base material which has a plurality of through holes and a gas-permeable sheet which has a flat part that is adhered to a lower surface of the base material and a plurality of recessed parts that are positioned below the through holes and that form the accommodating parts by closing the through holes.
Claims22
A culture plate comprising:
- a plurality of accommodation parts for culturing cells;
- a base material including a plurality of through-holes;
- and
- a gas-permeable sheet, the gas-permeable sheet including:
- a flat surface part attached to a lower surface of the base material, and
- a plurality of recesses disposed below the through-holes so as to close the through-holes and form the accommodation parts.
3 more elements
A method for manufacturing a culture plate, the method comprising:
- providing a base material including a plurality of through-holes;
- obtaining a gas-permeable sheet by deforming a planar sheet and forming a plurality of recesses at positions corresponding to the through-holes;
- and
- bonding the gas-permeable sheet to the base material in a state in which the plurality of recesses are disposed at positions of the plurality of through-holes.
1 more element
A method for manufacturing a culture plate, the method comprising:
- providing a base material and a jig in a combined state, the base material including a plurality of through-holes, the jig including a protrusion at a position corresponding to the plurality of through-holes;
- disposing a gas-permeable sheet on a first surface side of the base material;
- and
- forming a recess in the gas-permeable sheet by pressing against the protrusion part the gas-permeable sheet that is heated, in a state where the protrusion part protrudes from the through-hole to the first surface side, and attaching the gas-permeable sheet to the base material.
