These CEPA centrifuges are designed for rapid cell removal and clarification of fermentation broth and similar liquid-solid mixtures in "clarifying" configurations; or for the separation of two liquids in "separating" configurations. Models range from a small lab unit, through large production-scale systems capable of processing up to 3000 L/hr. All use bottom feed, retain solids in the bowl and expel supernatant from upper tray(s). All wetted surfaces are stainless steel (except optional silicone bottom valve). All floor models feature 3-phase electric motors for rapid acceleration. Basic configurations include one bowl, ancillary equipment, and tools.
