An apparatus for filling a cartridge with medical gas, comprising a sealing mechanism designed to removably seal against the open end of an uncapped and empty cartridge, evacuate the cartridge, producing at least a partial vacuum therein, fill the cartridge with medical gas at a predetermined pressure and temperature, and maintain the predetermined pressure and temperature while the cartridge is capped is presented.

Apparatus for filling pressurized gas cartridges for medical use

A system for preparing a refrigerant sample for analysis including a pressure regulator assembly including a pressure regulator and provisions for heating a refrigerant sample contained within an interior region of the pressure regulator. The pressure regulator defines an inlet through which the refrigerant sample is delivered and an outlet through which the refrigerant sample is expelled. The system also includes a filter assembly having an inlet that is fluidly connected to the outlet of the pressure regulator to receive the vaporized refrigerant sample from the pressure regulator, at least one filter for removing contaminants from the refrigerant sample, and an outlet that is configured to be coupled to a refrigerant analysis system for analyzing a composition of the refrigerant sample.
