Kurigatani tekinoroji idasanzwe yo gutandukanya ibintu, itandukanye na distillation gakondo ishingiye ku ihame ryo gutandukanya itandukaniro. Ubu ni inzira yo gusibanganya no kweza ibintu byangiza ubushyuhe cyangwa ibintu bitetse cyane ukoresheje itandukaniro munzira yubusa yimikorere ya molekile munsi yumuvuduko mwinshi. Ahanini ikoreshwa mubimashini, imiti, peteroli, ibirungo, plastike namavuta nizindi nganda.
Ibikoresho byimurwa bivuye mu cyombo cyo kugaburira mu buryo bwa disillation jacketted evaporator. Binyuze mu kuzenguruka kwa rotor no gushyushya guhoraho, amazi yibikoresho arasakara muri firime yoroheje cyane, yuzuye imivurungano, hanyuma igasunikwa hepfo muburyo bwa spiral. Mugihe cyo kumanuka, ibintu byoroheje (bifite aho bitetse) mumazi yibintu bitangira guhinduka, kwimukira muri kondereri yimbere, hanyuma bigahinduka amazi atemba agana kumurongo wakira flask. Ibikoresho biremereye (nka chlorophyll, umunyu, isukari, ibishashara, nibindi) ntibizimuka, ahubwo, bitembera kurukuta rwimbere rwumuyaga mwinshi mubyiciro biremereye byakira flask.
