Concentration Techniques : Introduction, Principle, Types ...

The concentration techniques principle works on specific gravity. By the addition of ethyl acetate to the formalin-fixed sample and subsequent centrifugation, the parasites present are heavier than the solution and settle in the sediment of the tube. Sample debris is typically lighter relatively and rises to the upper layer of the test tube.

flotation method 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..
