Abstract
A measurement device containing one or more capillaries to measure the volume of a dispensed fluid and determine the volumetric accuracy of the dispensing device. The measurement device can contain a reservoir containing the fluid to be measured and there may be an additional reservoir for a secondary fluid. A viewing window is necessary to complete a manual measurement and may include a magnifying lens. The liquid well by the capillary inlet may be shaped such that the measurement fluid is directed toward the capillary. The well may have features designed to position the dispensing device toward the capillary, or to position the well proximal to the capillary after it is filled. The well may also have surfaces or coatings which attract or do not attract various types of substances. The measurement device may interface with sensors to output measurement data.
