    Abstract: A diagnostic cassette includes a substrate, to physically and electrically connect the product to a computing device, a reservoir defined within the substrate to receive a fluid sample for processing by the diagnostic cassette, a reagent to react with the fluid sample deposited in the reservoir to form a solution to enable processing of the fluid sample by the diagnostic cassette, a channel to direct the solution, and a sensor to measure a number of parameters of the solution passing through the channel. A method for measuring microfluidic samples includes receiving, in a reservoir, a fluid sample to be measured, combining the fluid sample with a reagent to create a solution, moving the solution through a channel, and measuring the solution, using sensors, as the solution passes through the channel.

    Abstract: According to an example, a fluid ejection device may include a fluid feed slot, a plurality of fluid ejection chambers in fluid communication with the fluid feed slot, a plurality of drop ejecting elements, in which a drop ejecting element of the plurality of drop ejecting elements is positioned within each of the plurality of fluid ejection chambers, a fluid circulation channel in fluid communication at a first end of the fluid circulation channel with the fluid feed slot and in fluid communication at multiple second ends of the fluid circulation channel with the plurality of fluid ejection chambers, and a fluid circulating element within the fluid circulation channel. The fluid ejection device may also include a bubble dissipating structure positioned within the fluid circulation channel outside of the plurality of fluid ejection chambers.
