Various implementations include a device for analyzing total organic carbon (TOC) within a fluid. The device includes a primary container, an input conduit, and an output conduit. The primary container is hollow and has a primary side wall and a primary end wall. The primary side wall has an inner surface defining a primary cavity and an outer surface opposite and spaced apart from the inner surface. The primary end wall includes a septum that is resiliently penetrable by an analyzer needle of a grab analysis port of a TOC analyzer. The input conduit has an input lumen. The input conduit extends through the primary container such that the input lumen is in fluid communication with the primary cavity. The output conduit has an output lumen.

A collector for collecting urine samples is placed inside a toilet with an extension lip placed on a toilet seat disposed on top of the toilet. Upon collecting urine inside the collector, a sample of urine is extracted from inside the collector. The collector may include a socket. The sealed container may be inserted into the socket to extract the sample of urine. A hollow sleeve may be disposed inside or outside the collector. Urine disposed inside the collector and inside the sleeve may attain the same fluid level responsive to a fluid passage between the collector and the sleeve at the bottom of the collector. The volume of urine extracted from the sleeve may be proportional to the urine collected inside the collector with a known proportionality constant.

A multiple port connecting assembly includes a connector body and a fluid isolation adapter. The connector body includes a first fluid passage extending from an adapter port to a first connector port, a second fluid passage extending from the adapter port to a second connector port, a first seat portion disposed between the first fluid passage and the second fluid passage, and a second seat portion disposed between the second fluid passage and an open end portion of the adapter port. The fluid isolation adapter is removably assembled with the adapter port and includes an adapter body defining a first end passage that connects with the first fluid passage, a second end passage that connects with the second fluid passage, a first seal portion sealing against the first seat portion, and a second seal portion sealing against the second seat portion.

The present invention provides an analytical sample container including an opening of at least about 40 mm and a resealable leakproof seal. The container contains a volume of a stabilizing liquid, including an alcohol, in an amount of at least about 2 mL and less than 50% of the volume of the container. A method of biosample collection is also provided. A mixture of a biosample and a stabilizing liquid from a leakproof sealed analytical sample container is analyzed. The stabilizing liquid includes an alcohol in an amount of about 2 mL to about 50% of a volume of the container.

A system may include a needle and source providing fluid to the needle. The system may include a sheath defining an opening. The needle may be within the sheath. The needle and sheath may define a cavity. The system may include a gasket movable between open and closed positions. The gasket may fluidly seal an end of the sheath so that the fluid exits the needle into the cavity and exits via the opening. The system may include a bottle including a septum proximate the end of the sheath. The system may include a movement system that may displace the gasket to permit fluid to exit the cavity via the end of the sheath and displace the sheath or needle such that the needle extends beyond the sheath. The movement system may displace the needle or bottle such that the needle penetrates the septum and fluid exits into the bottle.

Systems, apparatuses, and methods for enhancing handling of a sample cylinder may include first, second, and third stations, each configured to receive a sample cylinder containing a material sample. The first station may include a first mounting fixture configured to be attached to the sample cylinder, a viewing glass to facilitate inspection of a portion of the material sample, and a first valve configured to remove a portion of the material sample from the sample cylinder. The second station may include a second mounting fixture and a second valve to provide fluid flow between a source of pressurized gas and the sample cylinder, thereby to pressurize the sample cylinder. The third station may include a third mounting fixture configured to be attached to the sample cylinder and a third valve to provide fluid flow between the sample cylinder and ventilation ductwork or a receptable.
