Hardware for magnetic 3D culture
First Claim
1. A magnetic cell culture system, comprisinga cell culture vessel, and a cap shaped to fit over or under said cell culture vessel, said cap including a lip around an outer edge of said cap, wherein said lip fits over and surrounding an outer edge of said cell culture vessel, said cell culture vessel having one or more wells, and said cap having one or more depressions on said cap corresponding to a center of the one or more wells, wherein one or more magnets are affixed to said cap inside said one or more depressions such that said one or more magnets sit above or below said cell culture vessel and do not touch a media in said cell culture vessel,wherein said cap comprises magnet position adjusters configured to adjust the position of said one or more magnets affixed into said one or more depressions in two or more of the three spatial directions, wherein the position of said one or more magnets can mechanically, electrically and/or magnetically be adjusted in said two or more of the three spatial directions, and wherein the cell culture vessel is a Petri dish, a cell culture flask, or a multiwell culturing plate.

1. A magnetic cell culture system, comprising
a cell culture vessel, and a cap shaped to fit over or under said cell culture vessel, said cap including a lip around an outer edge of said cap, wherein said lip fits over and surrounding an outer edge of said cell culture vessel, said cell culture vessel having one or more wells, and said cap having one or more depressions on said cap corresponding to a center of the one or more wells, wherein one or more magnets are affixed to said cap inside said one or more depressions such that said one or more magnets sit above or below said cell culture vessel and do not touch a media in said cell culture vessel, wherein said cap comprises magnet position adjusters configured to adjust the position of said one or more magnets affixed into said one or more depressions in two or more of the three spatial directions, wherein the position of said one or more magnets can mechanically, electrically and/or magnetically be adjusted in said two or more of the three spatial directions, and wherein the cell culture vessel is a Petri dish, a cell culture flask, or a multiwell culturing plate.
- 8. A magnetic cell culture vessel, comprising a vessel having a plurality of wells in an array, a cap covering said plurality of wells, said cap having a lip surrounding an outer edge of said vessel and a plurality of magnets in an array affixed to said cap, such that each well of said plurality of wells has a magnet of said plurality of magnets over or under said well at a center of said well and said magnet does not touch a media in said well when said cap sits in place over or under said vessel, wherein said cap comprises magnet position adjusters configured to adjust the position of said one or more magnets affixed into said one or more depressions in two or more of the three spatial directions, wherein the position of said one or more magnets can mechanically, electrically and/or magnetically be adjusted in the two or more of the three spatial directions, and wherein the vessel is a Petri dish, cell culture flask, or a multiwell culturing plate.

11. A magnetic drive, comprising a cap sized to fit over or under an ANSI/SLAS microtiter plate having a plurality of wells,
said cap having a lip around an outer edge thereof, said lip fitting around an outside edge of said ANSI/SLAS microtiter plate, said cap having a plurality of depressions having a plurality of magnets affixed thereinto, such that each well of said plurality of wells has a magnet of said plurality of magnets over or under said well at a center of said well when said magnetic drive is disposed over or under said ANSI/SLAS microtiter plate such that said magnet does not touch a media in said well, and wherein said cap comprises magnet position adjusters configured to adjust the position of said one or more magnets affixed into said one or more depressions in two or more of the three spatial directions, wherein the position of said one or more magnets can mechanically, electrically and/or magnetically be adjusted in said two or more of the three spatial directions.
