摘要:
Apparatus and methods of mixing and dispensing small samples are 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.

Apparatus and methods of mixing and dispensing small samples are 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 such as a helical spring (28) which is compressible towards the impeller under applied load. 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.
