sulfate flotation concentration in parasitology

  • 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.Operculated eggs as well as schistosoma and infertile Ascaris

    The egg opercula pop open due to the high specific gravity of the zinc sulfate, fill with zinc sulfate, and sink to the bottom of the tube. Therefore, using this method, both the surface film and sediment must be examined before reporting the concentration as negative. REFERENCES. Garcia, L.S. 2016.
