Rotors

  • Sorvall rotors
    • Rotors we have:
      • SS-34. Holds 8*50 mL, spins at 20,000 RPM/36,900 RCF
      • GS-3.
      • ____. Holds eppendorf (1.5mL) tubes
  • For reference, the benchtop 50mL centrifuges (e.g. ST-15R with a TX-400 swinging bucket rotor) we have spin at 4696 RCF.

Instructions

Example protocol for AM1:

Janet's SIP3-4 centrifugation:

  • Chill to 4oC with SS-34 rotor inside
  • Fill correct tubes
  • Spin for ___ min at ___ RCF at ___oC

Centrifugation Math & Basics

  • Sigma summary:
    • sedimentation rate is proportional to RFC, and proportional to the square of the particle diameter (cell diameter).
    • Stoke's equation
