Gewinnung repräsentativer Wassermischproben mit einem einfachen kontinuierlichen Sammelgerät

The sampling device consists of a weighted wide-necked bottle with a siphon pipe inserted in its top through which water enters the bottle while air escapes out of the bottle through a pipe with a valve that is inserted in the top, too. Due to the variable setting of the valve the period of time for the filling of the bottle can be controlled between few minutes and up to 24 h.
