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 120 and can then be skimmed from the top of the tube The most commonly used reagent is zinc lated eggs as well as schistosoma and infertile Ascaris ...As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.Get Price

May 03 2016 · 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 techniqueMore Details
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 sppMore Details
Sheathers sugar solution which can be homemade see Recipe for Sheathers sucrose solution or purchased commercially has a higher specific gravity 127 than standard salt solutions such as zinc sulfate specific gravity of 118 or sodium chloride and sodium nitrate specific gravity of 118 to 120 This characteristic makes it aMore Details
Flotation medium will distort larvae and rupture protozoa trophs Note that this same “fixed head procedure” can be used in a swing head centrifuge 3 Swinging Head Centrifuge – for Giardia Standard Qualitative Fecal wZinc Sulfate 1 Weigh out estimate 2 or 5 grams of feces 2 Mix with 10ml of Zinc Sulfate solution 3More Details
However the zinc sulfate procedure was more effective for the detection of protozoan cysts Hymenolepis nana and hookworm eggs The results indicate that the Formalinethyl acetate procedure provides a suitable alternative to the Formalinether method and they demonstrate the value of using both flotation and sedimentation procedures in theMore Details
