Systems and methods for performing measurements of one or more materials are provided. One system is configured to transfer one or more materials to an imaging volume of a measurement device from one or more storage vessels. Another system is configured to image one or more materials in an imaging volume of a measurement device. An additional system is configured to substantially immobilize one or more materials in an imaging volume of a measurement device. A further system is configured to transfer one or more materials to an imaging volume of a measurement device from one or more storage vessels, to image the one or more materials in the imaging volume, to substantially immobilize the one or more materials in the imaging volume, or some combination thereof.

A control section causes one dispensing mechanism of either a reagent dispensing mechanism or a sample dispensing mechanism to first discharge a predetermined amount of a liquid into the reaction container, and then, with respect to the cases where the amount of a liquid to be discharged by the other dispensing mechanism is larger or smaller than the amount of the liquid in the reaction container, causes the other dispensing mechanism to discharge the liquid such that the discharge speed in the case where the amount of the liquid to be discharged is larger is decreased relative to the discharge speed in the case where the amount of the liquid to be discharged is smaller.

The automatic analysis device 100 is provided with: a specimen dispensing mechanism 101 that dispenses subject blood plasma and/or normal blood plasma to be added to correct the coagulation time of the subject blood plasma, into a plurality of specimen containers 103; reaction containers 104 that contain the subject blood plasma and/or the normal blood plasma; a reagent dispensing mechanism 106 that dispenses a reagent into the reaction containers 104; and a detecting unit 113 which applies light from a light source 115 to the subject blood plasma and/or the normal blood plasma to which the reagent is added in the reaction containers 104, and which measures the coagulation time on the basis of the obtained scattered light and/or transmitted light.

A jet-mixer for a fluid mixing system includes a housing including a mixer port formed in an inner surface of the housing, and a rotor rotatably disposed in the housing, the rotor including a rotor blade, wherein the rotor includes a first angular position in the housing restricting fluid flow through the mixer port, and a second angular position allowing fluid flow through the mixer port, wherein, in response to rotation of the rotor in the housing, the jet-mixer is configured to inject a first fluid jet through the mixer port into the passage of the fluid conduit that has a pulsed velocity profile.

The present invention is to provide a flow cytometer comprising: flow cell; a liquid feeding unit for feeding a liquid different from a sample liquid containing sample particles to the flow cell; a sample liquid feeding unit for feeding the sample liquid to the flow cell after the liquid is sent to the flow cell; and a detector for detecting the sample particles flowing through the flow cell.

The present invention is related to the field of microfluidics and compound distribution within microfluidic devices and their associated systems. In one embodiment, present invention aims to solve the problem of molecule and compound absorbency into the materials making up laboratory equipment, microfluidic devices and their related infrastructure, without unduly restricting gas transport within microfluidic devices.

A receptacle comprises opposed members, a plurality of chambers having perimeter walls defined by seals formed between the opposed members and portals interconnecting the chambers, and a rigid frame supporting the opposed members at their peripheral edges. The frame comprises a front frame portion and a rear frame portion, and the peripheral edges of the opposed members are retained between the front and rear frame portions. An inlet port extends between the front and rear frame portions and is in fluid communication with one of the chambers.

A method of processing a sample in a receptacle comprising a plurality of chambers. Each of the chambers is connected to at least one other chamber by a portal and at least a first one of the chambers is formed of a flexible material. The method includes the steps of causing gas bubbles contained in the first chamber to accumulate in a portion of the first chamber, applying a compressive external force to the first chamber to cause some or all of the liquid contents of the first chamber to flow into an interconnected second chamber through a portal connecting the first and second chambers; and preventing the gas bubbles accumulated in a portion of the first chamber from flowing through the portal into the second chamber
