Provided are systems and methods for collecting and storing a microbiome-derived gaseous sample.

A biological sample collection system can include (i) a sample collection vessel having an opening for receiving a biological sample, (ii) a plug assembly that includes a post with a fluid vent therethrough, a collar disposed about the post, and a plug that initially obstructs the fluid vent, and (iii) a sealing cap coupled to the collar and comprising a reagent chamber for storing a sample preservation reagent. The sealing cap is configured to associate and form a fluid tight connection with the sample collection vessel such that associating the sealing cap with the sample collection vessel causes a physical rearrangement of the plug assembly such that the plug is detached from the post, thereby permitting sample preservation reagent to pass from the regent chamber to the sample collection vessel.

The present invention relates to an assay device for determining the presence and/or amount of an analyte of interest in a sample, the assay device comprising: a) a housing that includes a liquid receiving unit that is adapted to accommodate one or more types of liquid; b) a mixing chamber adapted for containing a solution that is a product of one more types of liquid, and for receiving a sample to interact with said solution; c) an actuating lid which is capable of being actuated to enable the transfer of the liquid into the mixing chamber; and d) an assay means that is in fluid communication with said mixing chamber for determining the presence and/or amount of an analyte of interest in the sample after the interaction of said sample with said solution in the mixing chamber.

Microarrays, hybridization seals and related methods. An apparatus includes a substrate including a plurality of probes and a hybridization seal. The hybridization seal includes an evaporation barrier and a layer including walls that form a grid pattern and define a plurality of sample chambers that are to receive fluid. The layer includes a first side removably coupled to the substrate and a second side that is coupled to the evaporation barrier. The evaporation barrier includes barrier sections that cover the probes and include one or more slits that allow the barrier sections to have a convex profile or a concave profile depending on an amount of the fluid within the corresponding sample chamber.

Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.

The present invention relates to a heat preservation shell (4) for an analyzer. At least one liquid passage (402) for conveying the liquid is embedded in a shell wall of the heat preservation shell. The liquid passage (402) is embedded in the shell wall of the heat preservation shell (4), on one hand, the liquid transported or preserved in the liquid passage is subjected to the heat preservation function of the heat preservation shell, so that the liquid transported or preserved in the liquid passage (402) maintains the preset temperature, thereby avoiding the influence of the external environment temperature on the transported liquid; and on the other hand, the space of the shell wall of the heat preservation shell is effectively utilized, the situation that various liquid pipelines are intricately distributed inside or outside the heat preservation shell (4) is avoided, thereby increasing the space utilization rate.

The present invention relates to a method and a system (400) for filling a closed container (200) with a fixative solution. The system comprises a container (200) comprising a container body (230) for receiving a biological specimen, a lid (220) for selectively closing the container body (230) and a port (100) forming a unidirectional barrier in a direction from the inside (IC) to the outside (OC) of the closed container (200). The system further comprises a dispensing apparatus (500) having a filling nozzle (300) for dispensing the fixative solution. The filling nozzle (300) is relatively moveable with respect to the container (200) between a retracted position and a filling position to fill the container (200) with the fixative solution.

Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.

A biological sample collection system includes (i) a sample collection vessel having an opening for receiving a biological sample, (ii) a selectively movable valve comprising a core and a collar disposed about the core, and (iii) a sealing cap coupled to the valve and including a reagent chamber for storing a sample preservation reagent. The valve is configured to retain the sample preservation reagent in the reagent chamber when the valve is in a closed configuration. The sealing cap is configured to associate and form a fluid tight connection with the sample collection vessel. Associating the sealing cap with the sample collection vessel causes the valve to be placed in an open configuration in which a fluid vent through the core is placed into fluid communication with the reagent chamber, thereby causing or allowing sample preservation reagent to pass from the regent chamber to the sample collection vessel.
