  • Method for vacuum concentration
    Patent number: 8857073
    Abstract: Vacuum concentrator, comprising a vacuum chamber with a closure which may be sealed in an airtight manner, a centrifuge rotor arranged in the vacuum chamber with at least one receiver for at least one vessel for samples to be dried, a drive motor arranged outside the vacuum chamber for driving the centrifuge rotor, a vacuum pump connected to the vacuum chamber, a tempering device associated with the vacuum chamber for tempering the at least one sample in the vacuum chamber, a pressure sensor associated with the vacuum chamber for detecting the pressure inside the vacuum chamber and an electrical control and evaluating device which is connected to the drive motor, the vacuum pump, the tempering device and the pressure sensor, for detecting the end point of the vacuum concentration by means of the pressures detected by the pressure sensor in the vacuum chamber and terminating the vacuum concentration when the end point is determined.
