A cuvette for analysis of liquids, including a first cuvette portion and a second cuvette portion, which are joined together, with a cuvette cavity, an inlet passage and an outlet passage being formed between the first cuvette portion and the second cuvette portion, the inlet passage and the outlet passage both in communication with the cuvette cavity, wherein the outlet passage is provided therein with a labyrinth-like sealing structure, which prevents backfill of a gas that has been discharged from the outlet passage during filling of a liquid to be analyzed in the cuvette.

An embodiment of the present disclosure provides a liquid collector that collects liquid, the liquid collector including: a flow passage member including a flow passage that connects one end and other end of the flow passage member; a contact member that is disposed at the one end of the flow passage member, that includes an elastic material, and that is configured to come into contact with a target from which liquid is to be collected; and a container that receives the liquid discharged from the flow passage at the other end of the flow passage member.

The present application provides a child-resistant liquid dispensing closure apparatus, which includes a plunger and pipet, and preferably a dosage measuring system that is integrated that appears as the plunger is withdrawn from the pipet. The closure may be used for a bottle containing a liquid for oral administration of solutions, syrups, suspensions, elixirs, tinctures, concentrates, and the like.

Registration of a patterned flow cell may utilize fiducials comprising sets or groupings of features (e.g., sites, sample wells, nanowells) having known locations and in which the placement of the features is not in accordance with a periodic pattern or is otherwise distinguishable from the periodic pattern of sites present in non-fiducial regions of the flow cell substrate. In certain embodiments the positioning of the sites that are part of the fiducial represent a break or discontinuity in the periodic pattern of sites that are otherwise present on the surface of a patterned flow cell.

[Problem] To ensure that a fluid is prevented from overflowing from a well and exposing the user to a biohazard. [Solution] A cartridge for use in measuring a component to be measured contained in a fluid includes a recessed well, formed for storing the fluid, the well including: a lower barrel portion that defines a lower space having a closed bottom; and an upper barrel portion that is formed above the lower barrel portion and defines an upper space having an opening on the top end, wherein a step portion is formed between the lower barrel portion and the upper barrel portion, the step portion being formed on an inner wall surface of the well and defining a step that continuously connects the inner wall surface of the lower barrel portion and the inner wall surface of the upper barrel portion.

Disclosed is a device including a substrate having a plurality of detection areas to receive at least a portion of a sample having an analyte or suspected of having an analyte and at least one reference marker adjacent to at least one of the detection areas, wherein each of the detection areas detects a specific analyte and the at least one reference marker defines a scale mark, a shape mark, a color mark, or a combination thereof. Also disclosed is an imaging system and method for using the device and imaging system.

Broadly speaking, embodiments of the present techniques provide a modular sample processing device which allows a user to perform any number of biological processes within a single device, in the order the user requires. The device is customisable—a user may select two or more modules and connect them in series to form the device in which the biological processing takes place. Advantageously, this may enable a user to perform multiple processes within a single device and potentially outside of a laboratory (e.g. during field work) or outside of sterile/aseptic environments. Furthermore, the device is a hand-held device, which means the device is compact and easy to transport and use for field work.

The present invention relates to a method for determining an analyte using surface enhanced RAMAN spectroscopy and to a device which is suitable for this purpose.

The present invention relates to a kit with which a user can conveniently and hygienically collect bio-samples using a collecting rod. A collection kit for collecting a bio-sample using a collection rod according to the present invention comprises: a cap on the lower part of the central part of which a filter is detachably mounted, wherein a cover is formed on the upper part of the filter; a collection rod having a collection unit and a handle part; and a tube fastened with the cap and for accommodating the extraction solution.

A liquid evaluation system can include a cartridge including a channel configured to pull a liquid into the channel by capillary action. The cartridge can include a first plate and a second plate located in close proximity to the first plate. An internal facing surface of each plate can include a corresponding region forming the channel. Each of the regions can have an affinity for the liquid. The close proximity of the plates and the regions having an affinity for the liquid cause the liquid to be pulled into the channel by capillary action. The cartridge can include one or more additional attributes and/or the system can include one or more additional components for performing the evaluation.
