Simple and portable seawater filtering device using pipette filler

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.
