An automated analyzer includes a rod-like member 12a, a driving portion 12c, and a control mechanism 30. The driving portion 12c lifts and lowers the rod-like member 12a a direction of being inserted into and removed from the container 24. The control mechanism 30 controls the driving portion 12c so that the rod-like member 12a is lifted after being lowered so that a tip portion of the rod-like member 12a reaches a first position in the liquid L, and at a time when the rod-like member 12a reaches a second position where the tip portion is not separated from the liquid, an upward motion of the rod-like member 12a is stopped for a given period of time to reduce liquid film adhering to the rod-like member.

A method of cleaning an aspiration tube in a specimen measuring apparatus includes: moving the aspiration tube while discharging a cleaning liquid onto an outer side surface of the aspiration tube; stopping the aspiration tube in a state where a tip of the aspiration tube or a droplet attached to the tip contacts a surface of a flow of the cleaning liquid; and moving the stopped aspiration tube in a direction away from the surface of the flow of the cleaning liquid.

Apparatus (2) for testing a liquid specimen, which apparatus (2) comprises: (i) a container (4) for the liquid specimen; (ii) a lid (6) for closing the container (4) after the liquid specimen has been provided in the container (4); (iii) first securing means (8) by which the lid (6) is secured to the container (4); (iv) a test capsule (10) for securing to the lid (6) when the lid (6) is on the container (4); (v) second securing means (12) by which the test capsule (10) is secured to the lid (6); and (vi) a response chart (14) which is operable in response to contact with the liquid specimen, and the apparatus (2) being such that: (vii) the lid has an openable portion (18) which when opened permits a liquid specimen in the container (4) to enter the test capsule (10); (viii) the test capsule (10) has opener means (20) for opening the openable portion on the lid (6) when the test capsule (10) is secured to the lid (6); and (ix) the response chart (14) is inside the test capsule (10) and is contacted by the liquid specimen when the liquid specimen enters the test capsule (10).

Systems and methods for delivering fluid to a microfluidic device is provided. The system includes a multi-well plate having a plurality of wells and an inlet tube having a first end being in communication with the one or more wells of the multi-well plate and a second end being in communication with a microfluidic device. The first end of the inlet tube is moveable between the plurality of wells of the multi-well plate to deliver fluid to the microfluidic device from the plurality of wells of the multi-well plate.

A pipette-fillable fluid reservoir body. The fluid reservoir body includes two or more discrete fluid chambers therein. At least one of the fluid chambers contains a pressure compensation device and at least another one of the fluid chambers is devoid of a pressure compensation device. Each of the fluid chambers is in fluid flow communication with a fluid supply via, and each of the fluid chambers have sidewalls and a bottom wall attached to the side walls, wherein the bottom wall slopes toward the fluid supply via. The fluid reservoir body also includes an ejection head support face in fluid flow communication with the fluid chambers for attachment of a fluid ejection device to the ejection head support face for ejecting fluid from the fluid chambers.

The present disclosure relates to a system for separating a sample including a device and a positive pressure source. The device can include a housing with a proximal end having an interface and a proximal end opening, a distal end opening opposite the proximal end opening, and an interior wall defining an interior of the housing; a bottom frit connected to the interior wall, extending across the interior of the housing, and located proximately to the distal end to minimize sample loss; and a resin disposed within the interior of the housing between the bottom frit and the proximal end. The positive pressure source can connect to the interface of the proximal end to apply positive pressure to the sample. A controller can control the applied positive pressure to the sample via the positive pressure source according to a relationship between the bottom frit, the resin, and the positive pressure.

In various implementations, a dropper for a bottle may include a bulb with a flange and an extended leg. The dropper may be used as a cap, in some implementations, with or without a skirt. The dropper may inhibit leaks from a bottle when the dropper is used as a cap for the bottle.

The invention relates to an assembly for contactless pressure-controlled release of a fluid comprising a non-compressible compartment, at least two fluids in fluidic contact and enclosed inside the non-compressible compartment, one of the two fluids being compressible, and one channel for fluid flow.

A washing apparatus includes a stage, a suction nozzle, and a control unit. On the stage, an analytical unit is mounted. In the analytical unit, a well having a hole shape including a bottom surface and an inner peripheral surface is formed. The suction nozzle sucks a solution in the well. The control unit, after controlling the suction nozzle to sucks the solution in the well, controls the stage to rotate the stage on which the analytical unit is mounted at a predetermined speed of rotation, and controls the suction nozzle to suck a residue of the solution existing in the well.

The specimen container according to one or more embodiments may include a container main body including an opening and a cap arranged to close the opening of the container main body and including a slit formed to allow an aspiration tube to pass therethrough. The cap according to one or more embodiments may include a slit-formed portion in which the slit is formed and an elastic portion provided to surround the slit-formed portion and that is elastically deformed to movably support the slit-formed portion.
