PROCEDIMENTO DI CONCENTRAZIONE DI CAMPIONI PER EVAPORAZIONE DEL SOLVENTE ED EVAPORATORE-CONCENTRATORE CENTRIFUGO PER LA REALIZZAZIONE DI QUESTO PROCEDIMENTO |
摘要 |
The centrifugal evaporator-concentrator comprises a central tubular pivot (18) surmounted by a nozzle (35) and constituting the pivot axis of a rotor (9) rotating in a vessel (8) closed by a cover (11). With the rotor rotating in the partial vacuum created by a vacuum pump (33), a small quantity of gas or air is temporarily and periodically admitted into the vessel, this gas being heated by a heating resistor (38) inside the vessel for the purpose of heating by conduction the specimens to be concentrated and of accelerating the rate of evaporation. |
