[Problems] Objects include providing a cover film for testing that can be well fixed to a substrate having a groove and does not adversely affect the groove, providing a testing member comprising the cover film for testing, and providing a method of manufacturing the testing member.

[Solution] The cover film for testing (1) comprises a base material (10) and a thermoplastic resin layer (20) laminated on one surface side of the base material (10). The thermoplastic resin layer (20) constitutes an outermost layer at one side of the cover film for testing (1).

[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.

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.

The invention relates to an apparatus comprising: a measuring head (10) having a slot (18) for receiving a measurement cell (26) and means (28) for emitting electromagnetic radiation, and means (32, 36) for detecting radiation from said emission means (28) after it has passed through the measurement cell (26); means (16) for translatably driving and means (12, 14) for translatably guiding, allowing the substantially vertical longitudinal movement of the measurement head (10); at least two recesses (44) each intended for receiving a measurement cell (26) and arranged one above the other in a longitudinal direction, the recesses (44) as well as the driving means (16) and the guiding means (12, 14) being configured such that during the translational movement of the measurement head (10) along the nominal travel thereof each recess is placed inside the slot (18) of the measurement head (10).

This inverted microscope comprises the following elements: an immersion objective lens, a medium container which is disposed above the immersion objective lens with a gap, and which has a bottom surface having a transparent portion and being capable of retaining a first immersion medium between the transparent portion and the immersion objective lens, and also which is capable of storing inside thereof a second immersion medium having a refractive index which is the same as or similar to that of the first immersion medium; and a movable stage to support a sample container, which accommodates a specimen, in a horizontally movable manner inside the medium container and which has a transparent portion in at least a part of a bottom surface thereof.

A detection system including a detection device and an assay device. The detection device includes a space for receiving an assay device, a drive arrangement engaging the assay device to rotate the assay device, a light source arranged to direct light towards the assay device, and a diffuser arranged to diffuse light from the light source. The diffuser is arranged between the light source and the space. The detection device includes a light receiver arranged to receive light from the light source that has passed through the assay device.

A plate assembly includes a first sample holder for receiving a plurality of samples, wherein the first sample holder is a transparent foil sheet and includes a plurality of cuvettes configured to receive a sample. A sample fixing plate for positioning the samples is placed in the cuvettes, wherein the sample fixing plate includes a plurality of inserts to be inserted into the cuvettes such that per cuvette a chamber is formed between the first sample holder and the inserted sample fixing plate. The chamber ensures the structural integrity of a single sample. At least one slot is formed next to each insert to allow the transmission of light emitted by the light-sheet microscope. The sample fixing plate also includes at least two opposite magnets and a sample holder frame for receiving the sample holder and the sample fixing plate fitted to each other. The sample holder frame has a planar flat sheet, which includes at least one receiving element configured to receive the first sample holder and the sample fixing plate inserted therein, wherein the bottom of the receiving element is made of transparent material. The sample holder frame includes a planar flat edge extending around the circumference of the sheet where the dimensions of said edge enable a scanning unit of a lightsheet microscope to operate continuously.

A method for analyzing a fluid sample by radiation. The method includes providing a cuvette having a cuvette body with an interior space for receiving the fluid sample, and an upper opening for filling and removing the fluid sample, and a lower opening for analyzing the fluid sample by the radiation, introducing the fluid sample into the interior space, irradiating the fluid sample with a primary radiation, and analyzing the fluid sample by receiving a secondary radiation originating from the fluid sample by a detection device.
