  • Publication number: 20250060288
    Abstract: 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.

  • Publication number: 20230087063
    Abstract: A dispensing assembly and related methods to facilitate dispensing of a fluid sample from a sample cylinder may include a sensor connected to one or more of conduits of the dispensing assembly and configured to provide indication of a leak in the conduits. A cap assembly may include a cap body and one or more cap conduits positioned to engage with a flush fluid source and provide fluid flow between the flush fluid source and a flush conduit. The cap assembly further may include a first quick connect coupler for connection and disconnection to a second quick connect coupler connected to a flush conduit. A pressure control device may be provided to prevent damage resulting from pressure to containers containing flush fluid. Inlet and outlet conduits connecting to the sample cylinder may configured to be flexible and align with corresponding connectors on the sample cylinder.
