Abstract

Wynalazek dotyczy urządzenia do kontrolowanego warstwowego nalewania cieczy, zwłaszcza do warstwowego nalewania cieczy rozdzielanych w procesie wirowania na gradiencie stężeń, przy czym urządzenie obejmuje komorę podawczą (11), komorę odpływową oraz element regulacji przepływu cieczy z komory podawczej (11) do komory odpływowej charakteryzującego się tym, że element regulacji przepływu cieczy obejmuje mechanizm tłokowy (19) oraz co najmniej jednej kanał przepływowy (32) znajdujący się w ścianie tulei przepływowej (31), przy czym mechanizm tłokowy (19) obejmuje tuleję przepływową (31) oraz ruchomy w niej osiowo tłok (20) wyposażony w trzpień (23) oraz wargę (22) szczelnie przylegającą do wewnętrznej powierzchni ściany tulei przepływowej (31). Wynalazek także dotyczy zestawu do wirownia na gradiencie stężeń obejmującego urządzenie do kontrolowanego warstwowego nalewania cieczy oraz pojemnik do wirowania.
