Systems and methods for facilitating placement of labware components
Certain configurations are described herein of a fluid handling apparatus that comprises a projector configured to provide an image of labware onto a support. The provided image can be used to assist a user in proper placement of the labware onto the support. The system can be configured to determine if the labware has been properly placed prior to beginning any fluid handling operations.
1. A fluid handling system comprising:
a support configured to receive at least one labware component at a labware site on the support; and
a projector configured to guide alignment of the at least one labware component at the labware site at least by providing an image of the at least one labware component onto the support;
at least one camera; and
a device comprising:
one or more processors; and
memory storing instructions that, when executed by the device, cause the one or more processors to assist in guiding the alignment by:
determining whether the at least one labware component is aligned on the support based on a comparison between one or more first pixels representing the at least one labware component and one or more second pixels representing the image of the at least one labware component;
causing the projector to provide the image using a first color based on the at least one labware component being aligned at the labware site; and
causing the projector to provide the image using a second color, different from the first color, based on the at least one labware component not being aligned at the labware site.
2. The fluid handling system of claim 1 , in which the projector is positioned above the support.
3. The fluid handling system of claim 1 , in which the projector is configured to provide a second image of a second labware component onto the support.
4. The fluid handling system of claim 1 , in which the projector is positioned below the support.
5. The fluid handling system of claim 1 , in which the projector is configured to project the image that is less than an entirety of the at least one labware component.
6. The fluid handling system of claim 1 , in which the support is configured to receive a microwell plate comprising a plurality of individual wells and in which the projector is configured to project an image of the microwell plate that is less than an entire image of the microwell plate.
7. The fluid handling system of claim 1 , in which the support is configured to receive a microwell plate comprising a plurality of individual wells and in which the projector is configured to project an image of the microwell plate that is an entire image of the microwell plate.
8. The fluid handling system of claim 1 , in which the projector is configured to project the image using visible light.
9. The fluid handling system of claim 1 , in which the projector is configured to project the image using non-visible light.
10. The fluid handling system of claim 1 , in which the projector comprises a DLP chip and a light source.
11. The fluid handling system of claim 1 , in which the projector comprises a liquid crystal panel and a light source.
12. The fluid handling system of claim 1 , in which the fluid handling system comprises a common light source that is used as a light source of the projector and as a light source of a detector of the fluid handling system.
13. The fluid handling system of claim 12 , in which the light source comprises a lamp, a light emitting diode, a laser, or a device that emits light.
14. The fluid handling system of claim 1 , in which the projector is further configured to project user instructions.
15. The fluid handling system of claim 1 , in which the image of the at least one labware component provided by the projector is at least 5% smaller than the at least one labware component.
16. The fluid handling system of claim 1 , in which the support comprises a reflective material.
17. The fluid handling system of claim 1 , in which the support comprises a material effective to diffuse light received from the projector.
18. The fluid handling system of claim 1 , further comprising a second projector configured to provide an image different from the image of the at least one labware component.
