Apparatus and method for mixing small samples of material

摘要

An apparatus and a method of mixing and dispensing small samples is described. Samples may be mixed in a small vessel (12) which is provided with an impeller (20) located at or adjacent its base (14) and driven by a shaft (22) extending through the base. Mounted for rotation within the vessel, either with the impeller or independently thereof, is an agitator means. Samples may be dispensed from the vessel using a piston member (40) having a through passage (44). The piston member is insertable into the vessel to force the sample therefrom through the passage.
