    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.Operculated eggs as well as schistosoma and infertile Ascaris
