TL;DR: In this paper, the axial impellers combination (3WHu) provides more effective homogenization performance than the impellers with combined radial and axial flow (HBT+2WHu, HBT+ 2WHd, HBLT+2Wu, and 3WHu), while the radial impeller combination is the worst.

TL;DR: In this article, power consumption, local and average volumetric mass transfer coefficient (k L a ) were compared for six impeller combinations in a 50L perspex tank with xanthan gum solutions.

TL;DR: The utility model provides a multifunctional testing device, during it will put same reactor into by detection electrode with as the standard electrode that the reference was compared to the parallel, reactor's contrast test condition is set for according to a predetermined detection project and after, observe and the record by detection electrodes and standard electrode's data, then according to data judgment by detecting electrode's performance, by detector electrode at least including miniature pH electrode and miniature oxide electrode, noncontact pH detecting system and the non -contact dissolved oxygen detection device of dissolving.

TL;DR: In this paper, a modular defoaming paddle and a combination formula defooaming paddle's miniature bioreactor should make up formula defobanding paddle and include paddle, retaining ring, and a pair of paddle level sets up in the outer lane of retaining ring.

TL;DR: In this paper, the authors present an electrode comparison testing method and a multifunctional testing device, which includes the steps of putting detected electrodes and a standard electrode as the parallel comparison reference into the same reactor, setting the comparison testing conditions in the reactor according to preset detection items, and judging the performance of the detected electrodes according to the data.
