flotation technique for fecal parasite concentration methods

this technique is predominantly used in parasitology laboratories by exploiting the density of the parasites particularly eggs 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 most commonly used reagent is zinc sulphate
