    Abstract: A microfluidic valve may include a firing chamber having an orifice, a first portion of a liquid conduit connected to the firing chamber at a first port, a second portion of the liquid conduit connected to the firing chamber at a second port and a thermal resistor. The thermal resistor is to form a bubble within the firing chamber to expel liquid from the firing chamber through the orifice such that a first meniscus forms across the first port and a second meniscus forms across the second port to interrupt liquid flow between the first portion and the second portion of the liquid conduit.

    Abstract: An object focuser may include a substrate, a sample fluid passage supported by the substrate, a first inertial pump supported by the substrate to pump a sample fluid entraining an object through the sample fluid passage, a first sheath fluid passage, a second inertial pump supported by the substrate to pump a first sheath fluid through the first sheath fluid passage, a second sheath fluid passage and a second inertial pump supported by the substrate to pump a second sheath fluid through the second sheath fluid passage. The first sheath fluid passage and the second sheath fluid passage are connected to the sample fluid passage at a convergence on opposite sides of the sample fluid passage.

    Abstract: An example device with a microfluidic channel for use in a chamber is provided, the example device comprising: a chamber to contain a fluid; a microfluidic channel located internal to the chamber, the microfluidic channel having an entrance within the chamber and an exit within the chamber, the microfluidic channel defined by a housing located within the chamber; a unidirectional displacement mechanism inside the microfluidic channel, the unidirectional displacement mechanism located between the entrance and the exit; and a controller to activate the unidirectional displacement mechanism to cause the fluid from the chamber to enter the microfluidic channel via the entrance and leave the microfluidic channel via the exit thereby agitating the fluid within the chamber, the fluid otherwise being non-moving.
