Centrifuge

Spins samples to separate mixtures by density, from blood fractions to macromolecules at extreme g-forces.

Core Principles & Analysis

• Ultracentrifuges reach accelerations around one million times gravity.
• Svedberg’s ultracentrifuge proved proteins are discrete macromolecules, earning the 1926 Nobel Prize.
• Sedimentation rates are still quoted in svedbergs — the unit behind ribosome names like 70S.
