The device (1) has an insulated tank (4) containing liquid gas (5) at a boiling point and arranged exchangers (6, 6', 6'') through gas streams to be cooled with exchangers that are connected with transfer lines (7, 7', 7''). An additional exchanger (8) ensures the pre-cooling of cold gas designed to cool a sample that is supplied with gaseous vapor (5') produced by the boiling of the liquid gas. Additional exchangers (8', 8'') ensure the pre-cooling of the cold gases to ensure the lift and rotation of the samples supplied by the gases that are evacuated. |
