    Abstract: A dual direction dispenser may include a fluid channel, a first ejection orifice extending in a first direction from the fluid channel, a first fluid actuator to displace fluid through the first ejection orifice, a second ejection orifice extending in a second direction, different than the first direction, from the fluid channel and a second fluid actuator to displace fluid through the second ejection orifice.

    Abstract: An example microfluidic mixer can include an inlet microfluidic channel portion and a fluid splitting channel portion including an overpass microfluidic channel to receive fluid from a first side of the inlet microfluidic channel portion and an underpass microfluidic channel to receive fluid from a second side of the inlet microfluidic channel portion, where the underpass microfluidic channel extends under the overpass microfluidic channel such that the channels overlap at their respective downstream ends. A fluid recombining channel portion is downstream of the fluid splitting portion and includes an angled recombining surface having an acute angle with respect to a direction of fluid flow, where the angled recombining surface is between the downstream ends of the overpass and underpass microfluidic channels. An outlet microfluidic channel portion is fluidly connected downstream from the fluid recombining channel portion.

    Abstract: An example method includes providing fluid to a chamber. The chamber feeds a first channel terminating at a first droplet ejector and a second channel terminating at a second droplet ejector. The method further includes sequencing ejection of droplets at the first droplet ejector and the second droplet ejector to induce negative pressure to provide a sequenced output flow of the fluid through the first channel to a first target microfluidic network and through the second channel to a second target microfluidic network, and controlling the first and second target microfluidic networks to perform an analytical process with the fluid.

    Abstract: An example device includes a chamber including a fluid inlet, a fluid outlet, and a negative-pressure port. The negative-pressure port is positioned relative to the fluid inlet to draw a droplet of a fluid from the fluid inlet into the chamber when the fluid is applied to the fluid inlet and negative pressure is applied to the negative-pressure port. The fluid outlet is positioned relative to the fluid inlet to collect the droplet. The example device further includes a downstream microfluidic channel connected to the fluid outlet of the chamber. The downstream microfluidic channel communicates capillary action to the fluid outlet of the chamber. The capillary action resists flow of the fluid from the fluid outlet into the chamber induced by the negative pressure applied to the negative-pressure port.
