CENTRIFUGE: Hand-driven

• Hand-driven Centrifuge useful for use in the school laboratory.

(Wikipedia excerpt: ..."..is a device that uses centrifugal force to subject a specimen to a specified constant force - for example, to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction.

At the same time, objects that are less dense are displaced and moved to the centre. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top.[1] A centrifuge can be a very effective filter that separates contaminants from the main body of fluid.

Industrial scale types are commonly used in manufacturing and waste processing to sediment suspended solids, or to separate immiscible liquids. An example is the cream separator found in dairies. Very high speed types able to provide very high accelerations can separate fine particles down to the nano-scale, and molecules of different masses. Large types are used to simulate high gravity or acceleration environments (for example, high-G training for test pilots). Medium-sized types are used in washing machines and at some swimming pools to draw water out of fabrics. Gas types are used for isotope separation, such as to enrich nuclear fuel for fissile isotopes...")
