Preparation and stability studies of emulsions

The physical stability of the emulsion is important to keep the dispersion intact. A stable emulsion is one in which the dispersed globules retain their character and remain uniformly distributed throughout b the continuous phase.

Determination of particle size by Sieve analysis

Particle that are placed on sieve set have uniform size of pore.when the sieve set is shaken normally the smaller particle are passed through the screen and higher particle are retained

Determination of HLB value of given surfactant

The hydrophilic-lipophilic balance of a surfactant is a measure of the degree to which it is hydrophilic or lipophilic, determined by calculating values for the different

Determination of flow properties of powder

Angle of repose is defined as the maximum angle possible between the surface area of the pile of powder and horizontal plane. The angle of repose is given by
