Abstract: 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.

Abstract: A device for inspecting microscopic objects. A plurality of LEDS is arranged in an array underneath a lens. Some of the LEDS are lighted and some of the LEDS are unlighted. A computer is in control of the LED array. The computer turns on selected LEDS from the array to form the lighted LEDS. Also, the computer turns off selected LEDS from the array to form the unlighted LEDS. The lighted LEDS form a pattern of lighted LEDS underneath the lens. In a preferred embodiment, the lens is connected to a computer controlled camera and the microscopic objects are microscopic crystals.

Abstract: 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 such that the opening of the liquid container defines a vertical position that is slightly below the liquid level 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 until the fluid level in the tray drops to a level approximately equal to the vertical position of the opening. The positioning of the syringe for drawing fluid is simplified by reason of the fact that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

Abstract: A device and method for the automated storage and retrieval of trays holding subject matter. A computer system is programmed to control a storage gantry to move the trays between a storage rack and an automated machine. In a preferred embodiment, the subject matter in the trays is a plurality of micro-well plates in which microscopic crystals may be growing and the automated machine is configured to inspect and classify microscopic crystals. The automated machine has an indexing device for sequentially placing microscopic crystals in camera-view of a camera and a control computer is programmed to control the indexing device and to cause the camera to take images of the microscopic crystals and then transfer the images to a classifying processor where the images are classified. In a preferred embodiment, the microscopic crystals are protein crystals that have been grown in the wells of micro-well plates.
