Provided are an automated analyzer for analyzing a substance contained in an unknown sample and a liquid reservoir, the analyzer and the reservoir being capable of saving users' operation without remarkably increasing the number of components. A flow path outlet of an overflow portion of the liquid reservoirs projects closer to the inner circumferential side of a drain flow path than to an inner circumferential surface side of an outer wall of the drain flow path serving as a destination to which liquid overflows. In addition, the flow path outlet projects so as to come into contact with an outer wall of the inner pipe. The flow path outlet of the overflow portion projects into the drain flow path so as to be located below an upper end of the outer wall of the drain flow path.

A gene sequencing substrate and a method for manufacturing the same, and a gene sequencing device are provided. It belongs to the technical field of gene sequencing, and can solve the problem of high cost of the high-throughput sequencing chip in the prior art. The gene sequencing substrate of the present disclosure comprises a plastic material with concave structures as base substrate, and the concave structures serve as reaction cells. Since the base substrate has plasticity, the concave structures can be formed by a simple process to reduce the cost of the gene sequencing substrate. Meanwhile, a first protective layer may be provided on the inner wall of the concave structures for preventing the inner wall of the concave structures from being corroded by the reaction liquid.

A microfluidic system can include a substrate comprising an elastic material and defining a microfluidic channel. The substrate can have a first set of dimensions defining a thickness of a wall of the microfluidic channel and a second set of dimensions defining a width of the microfluidic channel. A transducer can be mechanically coupled with the substrate. The transducer can be operated at a predetermined frequency different from a primary thickness resonant frequency of the transducer. A thickness and a width of the transducer can be selected based on the first set of dimensions defining the thickness of the wall of the microfluidic channel and the second set of dimensions defining the width of the microfluidic channel.

(57) Abstract: The present invention relates to a container (1) for small liquid volumes having at least one inlet chamber (2), at least one outlet chamber (3), an open top end (4) and a bottom end (5), wherein the bottom end (5) comprises at least one access region (7); wherein the at least one inlet chamber (2) is capable of accommodating a swab stik (16); wherein the at least one inlet chamber (2) has at least one open top end (11a) and is connectable to at least a first free end (8) of a flowpath (9) via the at least one access region (7); and wherein the at least one outlet chamber (3) has at least one open top end (11b) and is connectable to at least another free end (10) of the flowpath (9) via the at least one access region (7); a kit, an interface for fluid handling, and a method for analyzing a sample liquid (18).

The present invention relates to a device (10) for use in fluid sample analysis. It is described to position (310) a top part (20) of the device (10) adjacent to a base part (30) of the device so as to define a fluidic receiving region in between, the top part being provided with a through opening fluidly connected to the fluidic receiving region, and the bottom part being provided with a radiation window adjacent to the fluidic receiving region. A fluidic sample is supplied (320) through the opening (24). The fluidic sample is moved laterally (330) in the fluid receiving region without the use of an intermediary membrane between the top part and the base part. A radiation is emitted (340) to the fluid receiving region. A radiation is detected (350) that is reflected by the device. A presence of the fluidic sample is determined (360) on the basis of a measured reflectance value based on the detected radiation.
