PROBLEM TO BE SOLVED: To provide an efficient apparatus and a method for vacuum concentration. SOLUTION: This vacuum concentrator comprises a vacuum chamber 2; a centrifuge rotor 3 arranged in the vacuum chamber 2 with a receiver for receiving a vessel for samples to be dried; a drive motor 6 for driving the centrifuge rotor 3; a vacuum pump 15 connected to the vacuum chamber 2; a tempering device 8 for tempering the sample in the vacuum chamber 2; a pressure sensor 17 for detecting the pressure inside the vacuum chamber 2; and a control and evaluating device 18 which is connected to the drive motor 6, the vacuum pump 15, the tempering device 8 and the pressure sensor 17, for detecting the end point of the vacuum concentration by means of the pressures detected by the pressure sensor 17 in the vacuum chamber 2 and terminating the vacuum concentration when the end point is determined.
