An apparatus and method for mixing materials such as reactants in a container which reduces or eliminates vortexing and swirling, improves mixing and eliminates degradation of the container and/or impeller comprises a container for holding liquids, a magnetic impeller coupled to a drive magnet located outside the container, where the impeller is suspended from a baffle assembly and located above the bottom of the container, a baffle assembly containing at least two vertical baffle elements with a horizontal cross member connecting the baffle elements, a portion or all of each of the baffle elements spaced from the wall of the container and a tube for providing liquid addition to the vicinity of the highly turbulent mixing around the impeller.

A mixer includes a shaft having first end and a second end. An impeller is mounted to the second end of the shaft while the shaft is rotated by a motor attached to the first end. The mixer includes a mixer support shaft and mounting bracket for mounting a diverter between the first end and the second end of the shaft.

A valve assembly for dispensing a measured quantity of a gelatinous semisolid material into a receptacle comprises a cylindrical housing provided with a piston actuatable to move through the throughbore of the housing to a cap provided with a cylindrical sleeve. Mounted within the sleeve is a hollow valve body connected to a sealing member having an end of circular cross-section and a slidable hollow cylindrical body provided with an orifice whose cross-section is substantially equal to that of the end of the sealing member. The barrel is connected to the valve body by springs. In the valve closed position the end of the sealing member is situated in the barrel orifice, preventing the dispensing of the gelatinous material; in the valve open position the barrel is pushed away from the sealing member, allowing the material to be dispensed. The barrel returns to the valve closed position after the material has been dispensed. In use, the material is introduced into the housing; weighing the valve assembly before and after dispensing enables the quantity of dispensed material to be verified.
