Centrifugation - Centrifuge Definition Centrifuge Machine ...

Centrifugation Definition. Centrifugation is the process that uses centrifugal force for the separation of two liquids in a mixture. In this process, the denser component of the mixture migrates away from the axis and the lighter component migrates towards the axis. The process of centrifugation is carried out in a centrifuge, as shown in Fig 7.

Dec 31, 2021 The centrifuge is used principally to extract and separate of uranium-238 and uranium-235. The gas centrifuge is based according to the plan of constant flow of gases into and out of the centrifuge unlike other centrifuges that work with batch processing. They are placed in cascades in order they can be split into two parts based on their isotopes.

Dec 31, 2021 What characteristic is used to classify aquatic biomes? Aquatic biomes can be generally classified based on the amount of salt in the water. Freshwater biomes have less than 1% salt and are typical of ponds and lakes, streams and rivers, and wetlands. Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries.
