A closure and a container assembly are disclosed. The closure includes a first visual identifier and a second visual identifier, wherein the second visual identifier is different from the first visual identifier. The first visual identifier may be a first color, and the second visual identifier may be a second color. At least one of the first and/or second visual identifier may include a fluorescent compound having a characteristic fluorescent spectra. The first visual identifier and the second visual identifier may be provided on the annular skirt of the closure. The fluorescent compound may be provided on at least one of the closure and the container assembly and can be used to facilitate automated visualization of the fluorescent compound under fluorescence excitation light.

Provided herein is technology relating to testing fluid specimens and particularly, but not exclusively, to apparatuses, devices, methods, systems, and kits for testing a fluid specimen, e.g. urine, saliva, or other body fluids, to detect specified chemical components in the specimen.

A bottle cap includes a lower cap body that is threaded for attachment about an opening in a solvent bottle and an upper cap body attached to the lower cap body. A liner disposed inside the lower cap body includes at least one opening to pass a solvent tube while limiting evaporation of the solvent in the bottle. Features in the upper cap body permit identification flags to be attached. Each flag has an opening to pass a corresponding tube and includes one or more characters or symbols, color-coding and/or shape-coding to identify the corresponding solvent and/or a system inlet to which the tube is connected at its other end. The upper and lower cap bodies are independently rotatable about a cap axis and allow the bottle cap to be removed from or attached to the bottle without the need to remove any tubes passing through the bottle cap.

The present disclosure relates to an automated assay system adapted to receive consumables in the conduct of an assay. The assay system includes at least one of a loading cart, a door support system, a waste storage unit, and a robotic subsystem. The loading cart is configured to organize and transport consumables necessary for the performance of the assay system. The door support system is configured to maintain stability of doors of the automated assay system. The waste storage unit is configured to provide convenient disposal of consumables associated with the automated assay system. The robotic subsystem is configured to transport consumables within the automated assay system.

A specimen collection assembly and method for detecting the same are disclosed. The specimen collection assembly includes a specimen collection container having an open top end, a closed bottom end, and a sidewall extending therebetween defining an interior adapted to receive a biological specimen. The specimen collection container also includes first indicia containing information. The assembly further includes a cap having thereon second indicia, the cap being removably engagable with the open top end of the container. The second indicia contains the same information as the first indicia.

A system for connecting a reagent container to a socket. The container has a cap with an outlet comprising a collar having an opening on its side, the collar surrounding a spout with a movable valve. The valve has a tube surrounded by a disk. A plug is centrally arranged within one end of the tube so the outer walls of the spout form-fit with the inner side of the tube and the inner walls of the spout form-fit with the outer side of the plug for closing the spout. The plug is connected to one end of the tube and a socket for accommodating the outlet of the container's cap. The socket comprises at least two movable levers to engage into openings of the collar and a socket gasket on one side for taking up the tube of the valve and tubing on the opposite side to drain liquids.

A sample vessel assembly, comprising a base member including a base flange having first and second opposing surfaces, first and second sides intersecting with one another; and a first sidewall extending from the first surface at a distance from the first and second sides; and a lid member, including: a lid flange having third and fourth opposing surfaces, third and fourth sides intersecting with one another; and a second sidewall extending from the third surface at a distance from the third and fourth sides, the second sidewall engageable with the first sidewall such that the first surface of the base flange and the third surface of the lid flange are in an opposing spaced-apart relationship with one another and such that the first and second sidewalls cooperate with one another to define a sample chamber. Further disclosed is a method for automated analysis of samples in a sample vessel assembly.
