Ultracentrifuges running at speeds upto 100000 rpm is normally used for the_____________________?
Correct answer: A. Separation of isotopes based on their density or molecular weights difference
- A. Separation of isotopes based on their density or molecular weights difference
- B. Concentration of rubber latex
- C. Separation of cream from milk
- D. Dewaxing of lubricating oil
Explanation
Ultracentrifuges operating near 100,000 rpm generate extremely high centrifugal fields, allowing separation of isotopes or molecules with small density or molecular-weight differences. Cream separation and latex concentration require much lower centrifugal intensities.
