Abstract

Systems and methods for creating a localized environment for a cell culture plate are described herein. An example system can include a dock shaped to receive the cell culture plate, and a gas distribution device positioned on the dock. The gas distribution device can include a frame including a plurality of sides connected to form an opening, an internal channel within the frame for directing a gas mixture within the gas distribution device, an inlet port in fluid communication with the internal channel for receiving the gas mixture, and a plurality of apertures in fluid communication with the internal channel. The plurality of apertures can be spaced apart from one another along the frame and configured to direct the gas mixture toward the opening.

Claims (28)

1. A system for creating a localized environment for a cell culture plate, comprising:

a dock shaped to receive the cell culture plate; and

a gas distribution device positioned on the dock, comprising:

a frame comprising a plurality of sides connected to form an opening;

an internal channel within the frame for directing a gas mixture within the gas distribution device, wherein the internal channel is disposed around the opening and is configured to direct the gas mixture around a periphery of the cell culture plate;

an inlet port in fluid communication with the internal channel for receiving the gas mixture; and

a plurality of apertures in fluid communication with the internal channel, wherein the plurality of apertures are spaced apart from one another along the frame and configured to direct the gas mixture toward the opening and around the periphery of the cell culture plate, and wherein the gas distribution device is configured to maintain a localized environment proximate the cell culture plate without disruption during physical interaction with the cell culture plate.

2. The system of claim 1 , further comprising a heater configured to provide heating energy to the cell culture plate.

3. The system of claim 1 , wherein the gas mixture comprises a CO 2 concentration of about 2-100%.

4. The system of claim 1 , wherein the gas distribution device provides a localized environment proximate the cell culture plate having a CO 2 concentration of about 0.5-20%.

5. The system of claim 1 , wherein at least some of the plurality of apertures are non-uniform in size.

6. The system of claim 1 , wherein the spacing between at least some of the plurality of apertures are non-uniform.

7. The system of claim 1 , wherein a cross sectional area of the internal channel varies along a length of the internal channel.

8. The system of claim 1 , wherein the dock and the gas distribution device respectively comprise complementary magnets, and wherein the magnets are positioned to align the gas distribution device on the dock.

9. The system of claim 1 , wherein the gas distribution device mechanically engages the dock.

10. The system of claim 1 , further comprising a lid configured to enclose the cell culture plate and at least a portion of the gas distribution device.

11. The system of claim 10 , wherein the lid comprises magnets configured to secure the lid to at least one of the gas distribution device or the dock.

12. The system of claim 10 , wherein the lid comprises a gripping feature configured to mate with a robotic gripper.

13. The system of claim 1 , further comprising a processor configured to determine a desired flow rate for the gas distribution device.

14. The system of claim 2 , wherein the heater is configured to support the cell culture plate within the dock.

15. A method for creating a localized environment for a cell culture plate, comprising:

introducing a pressurized gas mixture into a gas distribution device positioned on a dock shaped to receive the cell culture plate, the gas distribution device comprising a frame comprising a plurality of sides connected to form an opening, an internal channel within the frame for directing the gas mixture within the gas distribution device, an inlet port in fluid communication with the internal channel for receiving the gas mixture, and a plurality of apertures in fluid communication with the internal channel, wherein the internal channel is disposed around the opening and is configured to direct the gas mixture around a periphery of the cell culture plate;

channeling the gas mixture within the internal channel of the gas distribution device;

expelling the gas mixture via the plurality of apertures in fluid communication with the internal channel, wherein the plurality of apertures are spaced apart from one another along the internal channel and are configured to direct the gas mixture at least partially toward the opening of the gas distribution device and around the periphery of the cell culture plate; and

maintaining, using the gas distribution device, a localized environment proximate the cell culture plate without disruption while a user physically interacts with the cell culture plate.

16. The method of claim 15 , further comprising providing a heater configured to provide heating energy to the cell culture plate.

17. The method of claim 15 , wherein expelling the gas mixture further comprises expelling a gas mixture having a CO 2 concentration of about 2-100%.

18. The method of claim 15 , wherein expelling the gas mixture forms a localized environment proximate the cell culture plate having a CO 2 concentration of about 0.5-20%.
