Rotors
Rotors we have:
- SS-34. Holds 8*50 mL, spins at 20,000 RPM/36,900 RCF
- Tubes:
- Can't be autoclaved.
- Actually, Amanda might have autoclaved them before.
- Can't write on body; can only write on cap. Sandy says stickers don't stick.
- Can't be autoclaved.
- Tubes:
- GS-3.
- For bigger bottles.
- ???.
- 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.
- There are stickers with maximum speeds. These were set by Katya, a Lidstrom Lab manager, circa 2011. It is unknown what the motivation was for keeping the rotors below maximum speed.
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).
