    摘要: A counterbalanced, dual submarine-type liquid mixer provides a pair of counterbalanced mixing devices that move at opposing ends of a balance bar (40) suspended above the surface of a liquid (10) to be mixed. The bar (40) is able to pivot so as to vertically move its ends (44, 46) alternately between a raised and a lowered position in such a manner that when one of the mixing devices is in a raised position in the liquid (10), the other of the mixing devices is in a lowered position and each of the two mixing devices tends to counterbalance the other.

    摘要: A pneumatic bioreactor includes a vessel containing a fluid to be mixed and at least one mixing device driven by gas pressure. A first embodiment includes a floating impeller that rises and falls In the fluid as gas bubbles carry it upward to the surface where the gas is then vented, permitting the impeller to sink in the fluid. The floating impeller may be tethered to a second impeller with a flexible member and pulley. The mixing speed is controlled with electromagnets in the vessel acting upon magnetic material in the impeller or its guides. In another embodiment, floating pistons mix the fluid, pushing it through a mixing plate with one or more apertures. In a third embodiment, the mixing device is a rotating drum vvith bubble-catching blades and rotating mixing plates with apertures. The top of the vessel for these mixers may include a closed top and sterile filters.
