Abstract
A concentrating vortex shaker for the simultaneous shaking and concentration of a multiplicity of liquid samples comprises a heat-conductive block having a plurality of openings for receiving laboratory vessels containing sample liquids and removably mounted on a base provided with an adjustable eccentric drive for displacing the block in a gyrating motion. An airtight cover is removably mounted on the block and forms a chamber above the samples which can be controllably evacuated. The samples can be heated or cooled by a temperature-controlled liquid which is fed through a channel formed in the block or heated by an adjustable electrical heater provided in the block mounting or cooled by a cooling plate, upon which the block mounts.
