The most commonly used reagent is zinc sulphate. Operculated eggs as well as schistosoma and infertile Ascaris eggs are not easily recovered by this method. Also trophozoites are

Read MoreTwo optical methods were used to determine the concentration of sugar (sucrose) solution. The first employed a hollow perspex prism, a prism spectrometer and a monochromatic light source. The angles of minimum deviation for different sugar samples were determined, whose values were used to compute the refractive indices of these samples.
