This invention relates generally to devices, systems, and methods for avoiding bubble formation in a fluidic chamber during filling of the fluidic chamber with a liquid. A first and second piece are operatively coupled to form the fluidic chamber. A protrusion protrudes into a volume of the fluidic chamber such that there is a distance of minimal approach between an apex of the protrusion and a surface of the fluidic chamber. The protrusion forms a channel that extends from one of an inlet and the outlet of the fluidic chamber to the protrusion apex. A maximum distance of travel through the fluidic chamber volume exists between the inlet and the outlet. A cross-sectional area of the fluidic chamber volume increases from the protrusion apex to a transverse plane of the fluidic chamber and decreases from the transverse plane to the other one of the inlet and the outlet.

Disclosed is a container rack configured to hold a plurality of containers, the container rack configured to be installed in a rack installation portion of a specimen analysis device, the container rack comprising: a holding portion including a plurality of holding holes through which body portions of the containers pass and which hold head portions of the containers; and a leg portion configured to support the holding portion, the leg portion provided from the holding portion to below the containers held in the holding holes, wherein the leg portion is configured such that the containers in the holding holes are exposed in a bottom view, and wherein the container rack is configured such that when the container rack is installed in the rack installation portion of the specimen analysis device, movement of the containers held in the holding holes is restricted by the rack installation portion.

Reusable network of spatially-multiplexed microfluidic channels each including an inlet, an outlet, and a cuvette in-between. Individual channels may operationally share a main or common output channel defining the network output and optionally leading to a disposable storage volume. Alternatively, multiple channels are structured to individually lead to the storage volume. An individual cuvette is dimensioned to substantially prevent the formation of air-bubbles during the fluid sample flow through the cuvette and, therefore, to be fully filled and fully emptied. The overall channel network is configured to spatially lock the fluidic sample by pressing such sample with a second fluid against a closed to substantially immobilize it to prevent drifting due to the change in ambient conditions during the measurement. Thereafter, the fluidic sample is flushed through the now-opened valve with continually-applied pressure of the second fluid. System and method for photometric measurements of multiple fluid samples employing such network of channels.

A blood testing device for detecting hemolysis in a blood sample is described. The blood testing device comprises an housing for containing the blood sample. The housing has a treatment window and an optical zone formed therein. The blood testing device further includes an acoustic transducer positioned to selectively generate acoustic forces directed into the treatment window of the housing and a control unit for selectively actuating and deactuating the acoustic transducer to permit colorimetric analysis of plasma within the blood sample.

An optical measurement device is provided. The device includes first and second optical fibers; first and second reaction vessels, and a light guide stage coupled to the first and second optical fibers. The light guide stage is driven to simultaneously optically connect the first and second optical fibers with the first and second reaction vessels. The device includes a measurement device for receiving emissions from the first and second reaction vessels, and a connecting end arranging body that supports the first and second optical fibers along a path. The arranging body is driven along the path between a first position, in which the first optical fiber is optically connected with the measurement device so that light is transmittable from the first reaction vessel, and a second position, in which the second optical fiber is optically connected with the measurement device so that light is transmittable from the second reaction vessel.
