摘要： A liquid evaluation system can include a cartridge including a channel configured to pull a liquid into the channel by capillary action. The cartridge can include a first plate and a second plate located in close proximity to the first plate. An internal facing surface of each plate can include a corresponding region forming the channel. Each of the regions can have an affinity for the liquid. The close proximity of the plates and the regions having an affinity for the liquid cause the liquid to be pulled into the channel by capillary action. The cartridge can include one or more additional attributes and/or the system can include one or more additional components for performing the evaluation.

摘要： A liquid evaluation system can include a cartridge including a channel configured to pull a liquid into the channel by capillary action. The cartridge can include an upper plate and a lower plate located in close proximity to the upper plate. The lower plate includes a deposition region for dispensing liquid. The extent of the deposition region in one or more directions can be defined by a repellant barrier, such as a boundary with a set of areas configured to be repellant to the liquid. An internal facing surface of each plate can include a corresponding region forming the channel. Each of the regions can be configured to have an affinity for the liquid. The close proximity of the plates and the regions having an affinity for the liquid cause the liquid to be pulled into the channel by capillary action.

摘要： 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.

摘要： 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.

摘要： A liquid evaluation device including a cartridge with one or more channels formed between two closely spaced substrates is disclosed. The cartridge includes one or more liquid flow structures, each of which can be located in a deposition region for a channel, an entrance region for the channel, and/or an interior region of the channel. Each liquid flow structure is configured to facilitate liquid flow to shape and/or locate the liquid in the channel for measuring a volume of the liquid located in the channel.
