A centrifuge is used to separate particles suspended in a liquid according to particle size and density, viscosity of the medium, and rotor speed. Within a solution, gravitational force will cause particles of higher density than the solvent to sink, and those less dense than the solvent to float to the top.
What are two practical uses of centrifuges?
Some common examples of centrifugation include:
- The extraction of fat from milk in order to produce skimmed milk.
- The removal of water from moist lettuce with the help of a salad spinner.
- The Spin-drying of water in washing machines in order to remove water from the clothing.
What is the importance of a centrifuge and why is it important?
A centrifuge is a piece of laboratory equipment used to separate heterogeneous mixtures. When the apparatus containing the mixture spins at a high speed, the centrifugal force pushes the heavier material to the bottom of the vessel. This helps separate the mixture based on differences in the density of the materials.
