Witryna24 mar 2024 · The agitation system typically consists of an impeller, a drive mechanism (magnetic or direct) and a motor. The goal is to deliver a power input into the culture medium to generate efficient mixing, and to get a homogeneous distribution of the temperature, DO and pH inside the bioreactor. Witrynathat the impellers act independently of each other, while our Applikon vessels are outfitted with a single impeller. An additive power number (Np) can then be used in calculations for a suitable power input. The resulting combined Np (1.3) of the UniVessel ® SU impellers is similar to the Np of the single impeller in the Applikon reading eps files
