ABSTRACT:
A mixer is intended for mixing substances, resuspending pellets and disintegrating living cells, such as yeast cells. The mixer includes a tube holder and an electric motor with striking attachment(s). The main part of the holder is rigid rings coaxial with and located subsequently along the motor shaft. Each ring has a number of holes the tubes sit in. Diameters of the holes are larger then diameters of the tubes, so that there are gaps between the tubes and the rigid rings. The attachment(s) of the motor is disks with blades, affixed to the motor shaft. When the motor shaft rotates the blades strike against the tubes. Struck tubes are repelled by the rigid ring (due to a gap between the tubes and rings), get a new strike from the blades and so on. As a result, the substance inside the tube receives a turbulent motion which provides mixing, resuspending and disintegrating effects.
