FIELD: agriculture.
SUBSTANCE: device comprises a heat-insulating housing with two heating chambers, an automatic switch, a programmable control unit of thermal mode and four quick-change covers: a cover for dry destruction with low maintenance insert in the heat-resistant containers of the heat-resistant cassette with a cup, restructured in the heating chambers, a cover for wet destruction with high maintenance insert in a sand bath in the heat-resistant containers of the heat-resistant cassette with a cup, restructured over the heating chambers, a cover for wet destruction in the heat-resistant tubes of the cassette with the tubes restructured with the required depth of immersion into the heating chambers, and a cover for wet destruction in Kjeldahl vials above the heating chambers.
EFFECT: invention enables to unify, simplify and accelerate the preparation of materials.
