Abstract
An apparatus for evaluating physicochemical properties of sample materials contained in an array of vessels includes: a light detector; a light source for transmitting a light beam through the sample material in a vessel to the light detector; an analyzer for processing data from the light detector to determine concentration-related properties of the sample material as a function of time; and a mixing system. The mixing system includes: a plurality of magnetic stirrer elements, each for being placed in a sample material in a different one of the array of vessels; an array of magnetic drive elements, each associated with a different one of the array of vessels and being magnetically coupled with a magnetic stirrer element in an associated vessel; and a drive mechanism coupled to the array of magnetic drive elements for simultaneously moving each of the magnetic drive elements relative to an associated vessel.
