<p>The vacuum concentrator has a pressure sensor (17) attached with a vacuum chamber (2) for detecting a pressure inside the vacuum chamber. An electrical control and evaluating device (18) is connected to a drive motor (6), a vacuum pump (15), a heating device (8) and the pressure sensor. The electrical control and evaluating device detects an end point of the vacuum concentration using the pressure detected by the pressure sensor in the vacuum chamber and terminates the vacuum concentration when the end point is determined. An independent claim is also included for a method for the vacuum concentration of samples.</p> |
