ROTARY VACUUM CONCENTRATOR

摘要

PURPOSE: A rotary vacuum concentrator is provided to freely control the inside temperature of a chamber through a cooling device and a heating device and to prevent pollution and deformation of a liquid sample by exactly analyzing a sample. CONSTITUTION: A rotary vacuum concentrator includes a chamber(3) receiving a sample rotating device(2) for rotating a liquid sample(1), a cooling tube wound on an outer side of the chamber, a heating device(5) mounted on a lower portion of the cooling tube, a cooling device(6) including the cooling tube, a controller(7) electrically connected with the heating device to control the temperature by a program, a gas supply device connected at a side of the chamber through a pipe(8). The gas supply device automatically injects sterilized gas and nitrogen gas into the inside of the chamber when a vacuum condition of the chamber is removed.
