Principle of Bioreactor An ideal Bioreactor Should Have Following Qualities  An ideal bioreactor should possess the following qualities: Bioreactor Design Important factors need to be consider in designing … Read more

A centrifuge uses centrifugal force in order to separate different components from a fluid. This is done by spinning fluid at high speeds within a container. It can then separate fluids with different densities (e.g. Cream from milk, or liquids and solids. It causes particles and substances that are denser to move in the radial … Read more
