This dispensing method includes a connection step for connecting a flange part (64) of a piston (65) and a drive member (50) that drives the piston (65), a first movement step for causing the drive member (50) to move to a first position so as to come into contact with the lower surface of the flange part (64), an intake step for raising the piston (65) to thereby take a liquid into a syringe (62) into which the piston (65) is inserted, a second movement step for causing the drive member (50) to move to a second position so as to come into contact with the upper surface of the flange part (64), a discharge step for lowering the piston (65) to thereby discharge the liquid inside the syringe (62), and a separation step for separating the flange part (64) and the drive member (50).

A system may include a first conduit configured to form a first batch of discrete volumes of aqueous fluid separated by spacing liquid disposed between consecutive volumes of aqueous fluid, the spacing liquid being immiscible with the aqueous fluid volumes; a second conduit, fluidically coupled to the first conduit, the second conduit configured to statically hold the first batch of discrete volumes of aqueous fluid; and a third conduit configured to receive the first batch of discrete volumes of aqueous fluid from the second conduit. The third conduit can be configured to transfer the discrete volumes of aqueous fluid of the first batch for downstream processing.

A nozzle includes a mounting opening that is to be connected to an opening portion of a container, an outlet that jets liquid stored in the container, a side face that connects the mounting opening to the outlet, and a liquid storage portion that stores a part of the liquid stored in the container in the nozzle without jetting a part of the liquid from the outlet in a case where the liquid is to be jetted from the dispensing container, that is, in a case where the outlet faces downward in the direction of gravity.

A liquid delivery device that includes a channel having an inner section lower than 9 mm.sup.2 and inner volume lower than 50 mL, a gas mass flowmeter connected to the inlet of the channel, and a pressure control unit suitable to control pressure inside the channel by flowing gas through the gas flowmeter.

An adjustable volume sampling system is disclosed for aseptically retrieving a sample volume of a fluid from an origination container. The system includes a sampling container. A cap is removably attached to the sampling container so as to close off the open top. The cap includes two ports. A first tube is attached to one of the ports. An elongated diptube extends through port into the sampling container and an upper end of the diptube is located inside a portion of the first tube. The diptube can be raised and lowered relative to the sampling container by pinching an stretching the first tube. Syringes are provided for expelling excess material from the sampling container.

A fluid delivery device includes at least one area onto which at least one support element having at least one well may be placed in a defined position. The fluid delivery device further includes at least one pipetting device having a connector configured to releasably connect the at least one pipetting device with a disposable tip and with a fluid displacement element which enables aspiration and ejection of a defined volume of liquid to or from the disposable tip. The at least one pipetting element is movable in a vertical and preferably in at least one horizontal direction. The fluid delivery device also includes a blowing element that has at least one aperture coupled to a source of pressurized gas and is movable in a vertical and preferably at least one horizontal direction. A system includes such a fluid delivery device and the at least one support element.

The present subject matter relates to systems and methods for the formulation of inks from stock solutions in which a liquid handler is configured to draw samples from a plurality of solution components and mix the components together to create one or more ink formulations, and a dispensing robot is configured to transfer the one or more ink formulations to a common substrate to form one or more material samples or a coating element in communication with the liquid handler is configured to transfer the one or more ink formulations to a common substrate to form one or more material samples. A controller in communication with each of the liquid handler and the dispensing robot can be configured to coordinate the creation and transfer of the one or more ink formulations. In addition, the one or more material samples can be analyzed using one or more characterization instrument configured to characterize the material samples on the common substrate.

A method for controlling a magnetic valve and particularly a method for dispensing and/or aspirating a volume of liquid as well as a corresponding dispenser/pipetting apparatus is disclosed. The method for controlling a magnetic valve has measuring a capacitance at the magnetic valve and determining a position of a plunger based on the measured capacitance. The method for dispensing or aspirating a volume of liquid has controlling a flow of a system fluid by a magnetic valve located between a pressure source and a dispenser/pipetting tip, dispensing or aspirating a volume of liquid through an exterior opening of the tip dependent on the flow of the system fluid, wherein controlling the flow and determining a flow time in dependence of the volume of liquid to be dispensed or aspirated, and controlling the magnetic valve is held open for the duration of the flow time.

The invention relates to a method for setting a cell concentration and/or a particle concentration in a dispensing device that has a fluid chamber into which a liquid sample is introduced that has a liquid and cells and/or particles, wherein the cell concentration and/or the particle concentration is determined, in particular in one region of the dispensing device, and the cell concentration and/or particle concentration that has been determined is compared with a target value and the cells and/or particles, in particular one or the other, that are present in the fluid chamber are moved or not moved as a function of the result of the comparison.

The present disclosure is directed to opposables including a body having a plurality of cavities disposed therein. Each cavity can be designed to contain one or more reagents, liquids, or fluids which may be applied to a specimen-bearing surface. In some embodiments, the cavities include one or more reagent chambers, the reagent chambers can have one or more seals such that the reagents, liquids, or fluids contained therein may be stored and released to the specimen-bearing surface.
