A device suitable for performing chemical and/or biological reactions, having a vessel 12 defining at least one reaction chamber 14 configured for holding liquids. Said chamber has at least one chamber inlet 22 and at least one chamber outlet 24. An upper mixing assembly 32a and a lower mixing assembly 32b are located inside the chamber 14, and each mixing assembly has a Venturi or eductor pump 36a, 36b, said pump having a motive fluid inlet (38, fig. 2), an aspirate inlet (40a, 40b, fig. 2) and an outlet (42, fig. 2), the Venturi pump 36a, 36b configured for accepting liquid contents of the chamber 14 into the motive fluid inlet (38, fig. 2) as motive fluid. The aspirate inlet may be in fluid communication with a gas or liquid reagent reservoir, and each mixing assembly can have an associated liquid-driving pump to drive motive fluid through said Venturi pumps. These liquid-driving pumps could be activated separately to one another. |
