Question

Principle of Centrifugation...​

Answer 1

Explanation:

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

Centrifugation is the process that uses centrifugal force for the separation of two liquids in a mixture. In this process, denser component of the mixture migrates away from the axis and lighter component migrates towards the axis. The process of centrifugation is carried out in a centrifuge. Centrifugation is used to seperate contents of mixtures in which the size of solute particles is so small that they easily pass through a filter paper.The principle is that the denser particles are forced to the bottom and the lighter particles stay at the top when the centrifugal machine rotates speedily.

Answer 2

CENTRIFUGATION

⏬In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it float to the top.

⏬The greater the difference in density, the faster they move. If there is no difference in density (isopyknic conditions), the particles stay steady.

⏬To take advantage of even tiny differences in density to separate various particles in a solution, gravity can be replaced with the much more powerful “centrifugal force” provided by a centrifuge.

⏬A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a potentially strong force perpendicular to the axis of spin (outward).

⏬The centrifuge works using the sedimentation principle, where the centripetal acceleration causes denser substances and particles to move outward in the radial direction.

⏬At the same time, objects that are less dense are displaced and move to the center.

⏬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.
