Disc-stack separation

Centrifugal clarification in which a stack of closely spaced conical discs multiplies the effective settling area, enabling continuous liquid-solid and liquid-liquid separation at 5,000-15,000 xg for cell harvest.

Where it's used

Disc-stack centrifuges
High-speed centrifugal separators that stack conical discs to multiply settling area, clarifying fermentation broth and cell culture at 5,000–15,000 ×g with continuous automatic solids discharge — the primary harvest and clarification machine of bioprocessing, now extending into gamma-irradiated single-use bowls for small-batch and perfusion work.
