Abstract
Filtration of seawater from the intertidal and
coastal areas for separating chlorophyll pigments
or particulate organic matter (POM) requires
vacuum and for creating vacuum, a suction pump
operated using AC/DC is essential. From the field
or sea, large quantities of water samples have to
be saved, brought to the laboratory and preserved
by freezing until the filtration. Seawater filtration
in remote areas with no power supply or portable
suction pump is difficult but can be made possible
by deploying a simple device involving filtering flask,
a rubber hose and a safety pipette filler
