A liquid dispensing device. The liquid dispensing device has a tray for holding a liquid at a relatively constant level. A syringe is used for drawing fluid from the tray. A liquid container containing a liquid is positioned upside-down in the tray. Atmospheric pressure on the liquid in the tray and a vacuum inside the liquid container prevents liquid from draining from the container except when the liquid level in the tray drops to a level sufficient to allow air into the liquid container and to allow fluid to flow from the liquid container into the tray. The fluid flows from the liquid container into the tray until the level of liquid in the tray returns to the relatively constant level. The positioning of the syringe for drawing fluid is simplified in that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

What is claimed is: 1. A liquid dispensing device, comprising: A. a tray for holding a liquid at a relatively constant level defining an approximately constant tray liquid level, B. a liquid container containing a liquid having an opening and positioned upside-down in said tray such that atmospheric pressure on the liquid in said tray and vacuum inside said container prevents liquid from draining from said container except when the liquid level in said tray drops to a level sufficient to allow air into said liquid container and to allow fluid to flow from said liquid container into said tray so that the level of the liquid in said tray returns to said approximately constant tray liquid level, and C. a syringe for drawing liquid from said tray, wherein positioning of said syringe for drawing fluid is simplified by reason of the fact that the level of fluid in said tray is maintained at said approximately constant level despite withdrawal of quantities of fluid from said tray. 2. The liquid dispensing device as in claim 1, wherein said tray is air-tight to allow for long term air-tight storage of fluid. 3. The liquid dispensing device as in claim 1, wherein said tray further comprises a threaded spin ring for attaching said liquid container to said tray. 4. The liquid dispensing device as in claim 3, wherein said liquid dispensing device is at least one liquid dispensing device, wherein said automated liquid handling device comprises: A. a robotic syringe grabber positionable above said at least one liquid dispensing device, B. at least one horizontal positioning linear actuator for horizontally positioning said robotic syringe grabber above said at least one liquid dispensing device, and C. a computer programmed to control said at least one horizontal positioning linear actuator and said robotic syringe grabber. 5. The liquid dispensing device as in claim 1, wherein said tray comprises a tapered opening to mesh with tapered diameter of said liquid container for an air-tight seal. 6. The liquid dispensing device as in claim 1, further comprising a locking syringe adapter for receiving said syringe. 7. The liquid dispensing device as in claim 1 wherein said syringe is a plurality of differently sized syringes, further comprising a plurality of interchangeable syringe adapters, each interchangeable syringe adapter configured to receive one of said plurality of differently sized syringes. 8. The liquid dispensing device as in claim 1, further comprising a syringe adapter for receiving said syringe, wherein said syringe adapter is engraved with the size of said syringe. 9. The liquid dispensing device as in claim 1, further comprising at least one syringe wiper for wiping off excess fluid on said syringe. 10. The liquid dispensing device as in claim 1, wherein said tray comprises a conically tapered inner tray bottom. 11. The liquid dispensing device as in claim 1, wherein said tray comprises a conically tapered inner tray top. 12. The liquid dispensing device as in claim 1, wherein said tray comprises: A. a liquid container receiving section for receiving said liquid container, and B. a syringe receiving section for receiving said syringe, C. an arched roof section between said liquid container receiving section and said syringe receiving section, wherein air flows from said syringe receiving section to said liquid container receiving section via said arched roof section and fluid flows from said liquid container receiving section to said syringe receiving section via said arched roof section. 13. The liquid dispensing device as in claim 1, wherein said syringe is manually removably inserted into said liquid dispensing device by the hand of an operator. 14. The liquid dispensing device as in claim 1, wherein said syringe is automatically removably inserted into said liquid dispensing device by the utilization of an automated machine, and wherein liquid is automatically transferred to a liquid receiving device. 15. The liquid dispensing device as in claim 14, wherein said automated machine comprises a barcode reader and said tray comprises a tray barcode, wherein said tray barcode comprises information indicative of the size of a syringe adapter attached to said tray. 16. The liquid dispensing device as in claim 15, wherein said tray barcode and said syringe adapter are color coded to match. 17. The liquid dispensing device as in claim 14, wherein said syringe means is manually removably inserted into said liquid dispensing device by the hand of an operator. 18. The liquid dispensing device as in claim 14, wherein said syringe means is automatically removably inserted into said liquid dispensing device by the utilization of an automated liquid mixing means, and wherein liquid is automatically transferred to a liquid receiving means. 19. A liquid dispensing device, comprising: A. a tray means for holding a liquid at a relatively constant level defining an approximately constant tray liquid level, B. a liquid container means containing a liquid having an opening and positioned upside-down in said tray such that atmospheric pressure on the liquid in said tray means and vacuum inside said container means prevents liquid from draining from said container means except when the liquid level in said tray means drops to a level sufficient to allow air into said liquid container means and to allow fluid to flow from said liquid container means into said tray means so that the level of the liquid in said tray means returns to said approximately constant tray liquid level, and C. a syringe means for drawing fluid from said tray means, wherein positioning of said syringe means for drawing fluid is simplified by reason of the fact that the level of fluid in said tray means is maintained at an approximately constant level despite withdrawal of quantities of fluid from said tray means. 20. A method for dispensing liquid, comprising the steps of: A. inserting a syringe into a liquid dispensing device, wherein said liquid dispensing device comprises: 1. a tray for holding a liquid at a relatively constant level defining an approximately constant tray liquid level, and 2. a liquid container containing a liquid having an opening and positioned upside-down in said tray such that atmospheric pressure on the liquid in said tray and vacuum inside said container prevents liquid from draining from said container except when the liquid level in said tray drops to a level sufficient to allow air into said liquid container and to allow fluid to flow from said liquid container into said tray so that the level of the liquid in said tray returns to said approximately constant tray liquid level, wherein positioning of said syringe for drawing fluid is simplified by reason of the fact that the level of fluid in said tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from said tray, B. drawing liquid into said syringe, C. removing said syringe from said liquid dispensing device, and D. dispensing liquid from said syringe into a liquid receiving device. 21. A liquid dispensing device, comprising: A. a tray for holding a liquid, B. a liquid container containing a liquid having an opening and positioned upside-down in said tray such that liquid from said container maintains a liquid level in said tray at an approximately constant liquid level such that atmospheric pressure on the liquid in said tray and the vacuum inside said container prevents liquid from draining from said container except when the liquid level in said tray drops to a level sufficient to permit a small quantity of liquid to drain from said container and to permit a small quantity of air to enter said container, and C. a syringe for drawing fluid from said tray, wherein positioning of said syringe for drawing fluid is simplified by reason of the fact that the level of liquid in said tray is maintained at an approximately constant level despite withdrawal of quantities of liquid from said tray.
