Ultracentrifuges running at speeds upto 100000 rpm is normally used for the_____________________?
Correct answer: D. Separation of isotopes based on their density or molecular weights difference
- A. Dewaxing of lubricating oil
- B. Concentration of rubber latex
- C. Separation of cream from milk
- D. Separation of isotopes based on their density or molecular weights difference
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.
