<p>Liquid sample sampling device has an evacuation orifice (22) connected to tubular needles (31, 32). A vent nozzle (13) and a central conduit (23) are connected to a tubular needle (33) between the needles (31, 32). The end of the needle (33) is placed inside a sample flask (2), above the ends (41, 42) of the needles (31, 32). The orifice determines a desired level (3) of a liquid sample in the flask. An independent claim is also included for a process of cleaning the above liquid sample sampling device.</p> |
