  • Publication number: 20240255538
    Abstract: A liquid dispensing device provides an input flow of liquid from a single inlet into an internal manifold, and distributes or divides the input flow from the manifold into a group of individual liquid circuits that direct respective output flows to outlets, from which controlled volumes of liquid can be dispensed into respective containers such as the wells of a multi-well plate. The volume of liquid dispensed into one container may be different from that dispensed into another container. Each liquid circuit may include a valve that regulates the liquid flow in that liquid circuit, which may be based on feedback from flow rate sensors. Two or more liquid dispensing devices may be stacked horizontally to provide additional unique liquid circuits and different liquids if desired.
