CDC - DPDx - Diagnostic Procedures - Stool Specimens

Flotation techniques (most frequently used: zinc sulfate or Sheather’s sugar) use solutions which have higher specific gravity than the organisms to be floated so that the organisms rise to the top and the debris sinks to the bottom. The main advantage of this technique is to produce a cleaner material than the sedimentation technique.

Zinc sulphate flotation of faeces. - CAB Direct

The zinc sulfate flotation technique for the concentration of eggs in faeces has been compared with the results of direct microscopical examination of faeces, and the tabulated results show that the zinc sulfate technique has great advantages over the faecal film in cases of infection with Ascaris lumbricoides, Trichuris trichiura, Ancylostoma sp. and Enterobius vermicularis, but in Taenia spp.

Silver Lead Zinc Ore Processing Method using Flotation

The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate. Over-grinding of silver minerals is detrimental to efficient flotation recovery, so the Flash Flotation Unit-Cell is used in the grinding circuit to recover a large part […]

Flotation Technique for Fecal Parasite Concentration

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
