home parasitology flotation technique for fecal parasite concentration methods flotation technique for fecal parasite concentration methods. it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube.
the microflotation process is more time consuming and costly than traditional flotation but it does recover more delicate plant remains and is less costly than geochemical methods. microflotation was used successfully to study soil samples from coal-contaminated deposits at chaco canyon.
