General Parasitology and Helminthology: Floatation technique

Floatation technique. 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.
