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 …
2013-5-1 · The concentration of phosphate flotation concentrate with P 2 O 5 grade lower than the commercially acceptable phosphate quality was upgraded in the use of tribo-electrostatic technique. The concentration of the flotation concentrate stream was conducted under both triboelectrification and inductive charging mechanism.
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.
