principle of centrifuge
Answers
Answer:
where centrifugal acceleration causes denser substance & particles to move outward in the radial direction . at the same time objects that are less dense are displaced and move to the center.
Answer:
Principle of centrifuge -
In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it floats to the top.
The greater the difference in density, the faster they move. If there is no difference in density (isopycnic 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
