Questions and Answers

What is the main purpose of ultracentrifuges in bioprocessing?

  • To clarify insulin liquor
  • To prepare bacterial enzymes by removing bacteria
  • To conduct colloidal research (correct)
  • To separate blood plasma from whole blood
  • How is a Filtration Centrifuge classified based on its mechanism of separation?

  • By the speed of centrifugation
  • By the porous medium through which liquid passes (correct)
  • By the size of the rotor used
  • By the type of particles to be settled
  • In bioprocessing, why should centrifugation be closely partnered with other process equipment?

  • To enhance the speed of centrifugation
  • To decrease the density difference of solid and liquid phases
  • To integrate the entire process effectively (correct)
