Abstract
A multipart chamber for cultivating cells for observing long-term cell cultures. Extremely small distances can be achieved between the objective of the microscope and the planes inside the chamber resulting for cell observation. Further, the chambers can have conduits attached thereto for feeding or draining liquid or gaseous materials therein.
Claims16
A microscope chamber for cultivating cells comprising:
- a multipart housing (1) with at least a first housing part (2) with a first recess (12) and a second housing part (6) with a second recess (12a);
- said first recess of said first housing part and said second recess of said second housing part arranged in axial alignment when said multipart housing is closed;
- said first housing part and said second housing part forming a portion of an interior of said microscope chamber;
- at least a first and a second sealing ring (15, 15a) each of which being positioned in said first recess (12) and said second recess (12a) and surrounding an axis of said first and second recess;
- first and second disks (13, 13a), each of which is provided on said first and second housing parts, which closes said interior of said microscope chamber to the outside and forms an observation window with said at least first and second sealing rings (15, 15a) resting against an inner surface of said first and second disks (13, 13a), with at least said first disk of said first housing part being supported on a surface facing away from an interior of said microscope chamber and being directly opposite to said first sealing ring (15) being supported on a holding plate (19);
- said holding plate having an opening (20) that exposes said observation window and is removably attached to said first and second housing parts;
- and
- a cell carrier ring (16) on which a cell carrier (17) is held, and which is positioned in between said at least first and second sealing rings (15, 15a), with said at least first and second sealing ring resting against said cell carrier ring (16) such that said interior of the chamber is divided into two separate part-chambers.
