## Picture

## 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

- Rotors we have:
- For reference, the benchtop 50mL centrifuges (e.g. ST-15R with a TX-400 swinging bucket rotor) we have spin at 4696 RCF.

## Centrifugation Math & Basics

- Sigma summary:
- sedimentation rate is proportional to RFC, and proportional to the square of the particle diameter (cell diameter).
