IMHOFF CONE. The Imhoff cone is used for the settleable BEAKERS. Beakers are common
solids testing of wastewater. pieces of laboratory equipment.
They come in sizes from 1 ml to
4000 ml. They are used mainly for
mixing chemicals and to measure
approximate volumes.
GRADUATED CYLINDERS. Graduated cylinders
also are basic to any laboratory
and come in sizes from 5 ml to
4000 ml. They are used to
measure volumes more accurately
than beakers.
