The maximum gas-liquid mass transfer capacity of 250ml shaking flasks on orbital shaking machines has been experimentally investigated using the sulphite oxidation method under variation of the shaking frequency, shaking diameter, filling volume and viscosity of the medium. The distribution of the l

In Part I of the article there were reported profound differences in behaviour between the bottom and the upper stages of a multiple-impeller vessel under gassed conditions: the volumetric mass transfer coefficient, kLa, for the bottom stage was by up to 50% lower than that for the upper stages. A p
