The present invention is related to the field of bio/chemical sampling, sensing, assays and applications. Particularly, the present invention is related to how to make the sampling/sensing/assay become simple to use, fast to results, highly sensitive, easy to use, using tiny sample volume (e.g. 0.5 uL or less), operated by a person without any professionals, reading by mobile-phone, or low cost, or a combination of them.

An autosampler sets an injection valve to be in a sample filling state when a sample loop is filled with a sample, and, after completion of filling with the sample, switches the injection valve to an intermediate state and first connects only one end of the sample loop to a liquid delivery channel and an analysis channel. After the above, the injection valve is switched to the sample injection state and the sample loop is interposed between the liquid delivery channel and the analysis channel, so that the sample is injected into the analysis channel.

An environmental sampling and assay system, having a coupon storage assembly, storing coupons; an environment sampling assembly, the sampling assembly mixing an environmental sample with a liquid to create a sample-liquid, bearing the environmental sample; a coupon moving assembly; a coupon wetting assembly for automatically wetting a coupon with the sample-liquid; a coupon perceiving device; a data input, adapted to receive a signal; and a data processing and control assembly, controlling the environmental sampling system, the coupon moving assembly, the wetting assembly and the coupon perceiving device. Further, the coupon moving assembly can retrieve a coupon from the coupon storage assembly and move it in a linear manner to the coupon wetting assembly.

It is provided a measuring cartridge (1) for measuring at least one constituent of a liquid sample, in particular blood, and for performing quality control, the cartridge comprising: a casing (3) insertable into a reception opening (51) of a measuring instrument (50), the casing (3) at least partly surrounding an inner space (5); wherein the inner space contains: a measurement cell (7) comprising a reception space (9) for the sample and at least one sensor area (11) with which the sample is in contact when loaded into the reception space (9); plural quality control containers (13a,13b,13c) for respectively holding different quality control solutions (15a,15b,15c); a solution routing system (17) adapted to selectively route one of the quality control solutions (15a,15b,15c) from the respective quality control container (13a,13b,13c) into the reception space (9) of the measurement cell (7).

A gas sampler (30) is provided with a connection portion (C1) connectable to a sample tank (20), a sample loop (PL) for holding a sample gas introduced from the sample tank (20) to the connection portion (C1), pneumatic switching valves (V1 to V6) for switching a flow path connected to the sample loop (PL), a control piping (81) for transmitting a driving pressure to the switching valves (V1 to V6), a pump (31) for suctioning an inside of the sample loop (PL), and a pressure accumulation tank (80) for accumulating the pressure generated by the operation of the pump (31) as a source pressure.

A digital slide scanning apparatus includes a safety light curtain that operates to disable the motor that rotates the carousel when the presence of an object (e.g., the fingers of an operator) is detected within a predetermined area of the carousel. The light curtain also operates to disable the motor that rotates the carousel when an improperly positioned glass slide or slide rack is detected. The digital slide scanning apparatus also includes a multi-color status indicator for each rack slot that indicates the rack slot location of an improperly positioned glass slide or slide rack.

A sample container for use in imaging includes a bottom portion and a wall portion extending upwardly from the bottom portion. The lid overlies the cavity when in the closed position, and a plurality of latches are coupled to the lid and extend substantially orthogonally from the lid. A plurality of recesses are coupled to the wall portion, each recess of the plurality of recesses being adapted and configured to receive one of the plurality of latches. A first alignment structure is within the cavity and is adapted and configured to align a sample lengthwise and widthwise within the cavity such that the sample is aligned relative to an imaging system when the sample container is engaged with the imaging system. A second alignment structure is at least partially within the cavity, and is adapted and configured to align the sample height wise within the cavity.

A medical device is configured to be attached to a part of a circulation circuit of an extracorporeal circulation device and to be inserted with an insertion member for performing a test related to blood clotting, and includes a storage portion configured to store a blood, and a main body portion configured to drop the blood stored in the storage portion onto the insertion member. The stored blood is used as samples for testing and monitoring of blood conditions (e.g., clotting) during extracorporeal circulation.
