Embodiment Construction

[0050] As described above, aspects of the present invention provide a fluid assessment system. The system can include a cartridge that includes a channel configured to draw liquid into the channel by capillary action. The cassette may include a first panel and a second panel positioned proximate to the first panel. The inwardly facing surface of each plate may include a corresponding region forming a channel. Each region may have an affinity for liquids. The close proximity of the plate and the areas that have an affinity for the liquid causes the liquid to be drawn into the channel by capillary action. A cartridge may include one or more additional properties and / or a system may include one or more additional components to perform the evaluation.

[0051] It should be understood that unless otherwise indicated, each value is an approximation and that every range of values ​​contained herein includes the endpoints defining that range. As used herein, unless otherwise state...

Abstract

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. Theclose proximity of the plates and the regions having an affinity for the liquid causes 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.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of US Provisional Application No. 62 / 479,513, filed March 31, 2017, which is hereby incorporated by reference. technical field [0003] The present disclosure relates generally to the evaluation of dispensed liquids, and more specifically, to liquid evaluation solutions using one or more channels in a cartridge. Background technique [0004] Liquid handling systems are essential tools and are widely used in laboratories used in biology, chemistry, and other fields. A common example of a liquid handling system is a pipette. Pipettes are used to transfer accurate volumes of liquids from one container to another, e.g. for analysis, chemical reactions, and other purposes. Pipettes generally include a piston placed at the end of the pipette which expels air. The piston can be operated to reduce the air pressure above the liquid to draw the liquid into the pipette tip, or to incr...
