EXTRACTOR Russian patent published in 2020 - IPC B01D11/00 

FIELD: technological processes.

SUBSTANCE: invention relates to extraction and concentration of trace impurities in analytical chemistry and relates to structures of mass- and heat-exchange apparatus used in sample preparation when determining content of contamination in environmental objects. Extractor can be used for solid-phase and liquid extraction and separation for various combinations of types of samples and solvents of different volume and ratios. Extractor comprises a base, a rotor with a drive and a retainer, a cover with a nozzle for sample introduction and suction tubes. Rotor is additionally equipped with a removable container installed in place of the collector, which is removable. At the bottom of the rotor there is a heater and a drain device; on the cover there is a mixer with vertically opposite doubles inclined blades and a telescopic shaft.

EFFECT: technical result consists in expansion of application area of device with reduction of extraction time and simplification of design.
