A standard Liebig condenser has a straight vapor path flowing through a coolant jacket and is so named because its use was made popular by a German chemist , Justus Baron Von Liebig , it was invented long before it had that name by another German chemist Christian Ehrenfried Weigel . My picture is simply a copy of a glass laboratory used condenser called a Davies condenser Not an inside out laburg or whatever
