Directions for any flotation technique must be followed exactly to produce reliable results. Formalin-Ethyl Acetate Sedimentation Concentration. By centrifugation, this concentration procedure leads to the recovery of all protozoa, eggs, and larvae present; however, the preparation contains more debris than is found with the flotation procedure.

floatation method of stool concentration

2020-10-19  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..

General Parasitology and Helminthology: Floatation

The principle is to use an emulsifying fluid of a greater specific gravity than that of the parasite eggs, which result in flotation of eggs in the solution. Thereby mere examination of the solution in the top most layer will clearly indicate the presence of egg. The faecal material and fiber settle at the bottom.
