Witryna• The number of impellers will depend on the height of the liquid in the reactor. Each impeller will have between 2 and 6 blades. Most microbial fermentations use a Rushton turbine impeller. • A single phase (ie. 240 V) agitator … 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
