Determination of surface tension by drop weight method
The stalagmometer is consist of a capillary bore with a bulb at the middle. The surface tension of the given liquid can be determined by using the following formula.
Determination of surface tension by drop count method
The stalagmometer consist of a glass capillarytube with a bulb at the middle.There is a capillary bore at the tip of the stalagmometer.
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.
