Abstract: A droplet dispensing apparatus includes a droplet ejection device, a microplate holder, and a sheet stand. The droplet ejection device has a solution holding vessel and an array of nozzles for ejection of droplets communicating with the solution holding vessel. The microplate holder is configured to hold a microplate into which the droplets are ejected. A test sheet being colored or discolored at a place where a light-transmissive droplet is received for testing the array of nozzles can be placed on the sheet stand. The droplet ejection device is configured to move to a first position above the microplate holder for ejection of droplets into the microplate and to a second position above the sheet stand for ejection of droplets onto the test sheet.

Abstract: A droplet dispensing apparatus includes a droplet ejection device, a microplate holder, a sheet stand, an image capturing device and a controller. The image capturing device is configured to move to a position above the sheet stand. The controller is configured to perform image processing on image data generated from an image captured by the image capturing device when the image capturing device is at the position above the test sheet on the sheet stand, to determine a size of each of test patterns formed by droplets dropped on the test sheet from the array of nozzles. The controller is further configured to generate a data file including the determined size of each of the test patterns. The test sheet colors or discolors at a place receiving a light-transmissive droplet.
