Decantation Definition. Decantation is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below. The process can be carried out by tilting the mixture after pouring out the top layer. This process can also be used to separate two ...

Magnetic separation. The increasing use of magnetic solid carriers in biochemical and molecular biology processes has many advantages compared to other non-magnetic separation processes. The term 'magnetic' means that the support obtains a magnetic moment when placed in a magnetic field. Thus, it can be displaced.
