An embodiment of the present disclosure is a sample vessel for a holding a sample for analysis by a sample analyzer. The sample vessel includes a body that includes a bottom, an open top spaced from the bottom along a first axis, a side wall that extends from the open top to the bottom, and an interior chamber for holding a sample and that extends from the open top toward the bottom along the first axis. The body includes an opaque portion, a first translucent portion, and a second translucent portion spaced from the first translucent portion a distance that extends along a second axis that is perpendicular to the first axis. The first and second translucent portions are each disposed along the bottom of the body.

A cuvette in which a fluorescent enzymatic reaction can be carried out that is for analyzing a sample includes at least one vertical wall and a bottom. The cuvette is made of a transparent or translucent material and a portion of the cuvette is partially covered on the outside with a sleeve including an inner coating made of retro-reflective material that is in contact with the cuvette.

[Problems] Objects include providing a cover film for testing which can be well fixed to a substrate having a groove and in which a pressure sensitive adhesive does not invade into the groove, providing a testing member comprising the cover film for testing, and providing a method of manufacturing the cover film for testing. [Solution] The cover film for testing (1, 2) comprises a base material (10) and a pressure sensitive adhesive layer (20) laminated on one surface side of the base material (10). The cover film for testing (1, 2) has a region in which the pressure sensitive adhesive layer (20) does not exist in the plan view.

The present invention relates to a system for conducting the identification and quantification of micro-organisms, e.g., bacteria in biological samples. More particularly, the invention relates to a system comprising a cooling, heating and fan arrangement for maintaining a predetermined optimum temperature of the samples during testing; a visual, circumferential and axial alignment system for aligning the samples within the carousel; a transfer system for transferring the samples from the carousel to the centrifuge; a balancing system of minimizing the rotational vibrations of the centrifuge; a safety system and anti-tipping design for the sample containing system; liquid dispensing arms for dispensing the buffered saline solution; and discharge ports for discharging and disposing of the liquid removed from the samples to a location external of the system.

A microfluidic apparatus has a microchannel that includes at least one vertically oriented segment with a top section having a relatively wide opening and a bottom section having a relatively narrow opening. The top section is larger in volume relative to the bottom sections, and the middle sections taper down in at least one dimension from the top section to the bottom section. One or tens or hundreds of vertically-oriented segments may be provided, and they are fluidly coupled to each other. Each segment acts as a pressure-volume-temperature (PVT) cell, and the microchannel apparatus may be used to determine a parameter of a fluid containing hydrocarbons such as the dew point of the fluid or the liquid drop-out as a function of pressure.

The present invention relates to a system for conducting the identification and quantification of micro-organisms, e.g., bacteria in biological samples. More particularly, the invention relates to a system comprising a disposable cartridge and an optical cup or cuvette having a tapered surface; an optics system including an optical reader and a thermal controller; an optical analyzer; a cooling system; and an improved spectrometer. The system may utilize the disposable cartridge in the sample processor and the optical cup or cuvette in the optical analyzer.

A gas sensor includes: a gas detection unit including a light source and a detector; and a gas passage including a first end, a second end and a hollow part. The hollow part has a shape in which a cross-sectional area of a flow passage grows smaller. The gas passage includes: a member that divides the hollow part into at least a first area and a second area; a gas inflow port; and a gas outflow port. The gas flows from the gas inflow port into the hollow part, flows in the first area to arrive at the gas detection unit, and the gas located in the gas detection unit flows in the second area and flows out from the gas outflow port.

A cuvette comprising a pyramidal shaped cavity with four sides surfaces, which are connected to each other by curves, wherein side surfaces and curves merge into a transition area that is located above a ring followed by a cone above the bottom of the pyramidally shaped cavity.

The invention relates to a counting chamber for a microscope, adjustable in height. The method measures a cell count at two different chamber heights and deduces the concentration of particles without an exact calibration of the absolute height, as the height difference gives a measurement of the missing volume and therefore an estimate of the particle concentration.
