Beschreibung
Zusammenfassung:	A cartridge for evaluating the volume of an aliquot of liquid is described. The cartridge can have one or more well tabs that pivot into a position in which liquid dispensed into a corresponding well is placed in contact with a capillary and surface tension draws the liquid from the well into the capillary. Comparison of the liquid-air interface with markings on or near the capillary, can reveal the volume of liquid dispensed. One or more additional features, such as well tabs that are stable in a substantially vertical orientation and/or a groove for protecting and/or self-aligning the capillary can ensure that the device operates properly.
