Basic physical properties of solutions with high precision are highly needed. The conventional devices can’t meet this demand. However, the magnetic suspension balance (MSB) could solve this problem. This paper summarizes the applications of MSB on the basic physical properties such as density, solubility, diffusion coefficient, adsorption, mass transfer, interfacial tension, specific volume, and so on. There is also a brief introduction about the measurement on fluid viscosity by the MSB after renovation.
