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.

Abstract: The present relates to a container and to a device for indirect material cooling and to a method for producing the container according to the invention. Through the present invention a much more efficient indirect heat transfer is facilitated from the exterior of the container into the interior of the container. The improvement of the heat conductivity and of the heat transfer of centrifuge containers yields a reduction of the necessary power of the refrigeration system for cooled centrifuges. Through the higher performance of the centrifuge a higher speed can be run for identical centrifuge temperatures and/or at the same centrifuge temperature and speed, the input power of the refrigeration unit can be reduced.

Abstract: A closure lock, in particular to a lock for a cover of a laboratory centrifuge and a housing of the laboratory centrifuge. The closure lock provides a particularly effective, loadable and safe lock which is not only actuatable through a power drive, but which also provides robust self blocking with respect to strong vibrations and high crash energies.

Abstract: A laboratory centrifuge according to the invention provides much better de-mixing rates of centrifuged samples since providing at least one rotation compressor introduces substantially less vibration into the laboratory centrifuge, so that much lower remixing rates are provided.

Abstract: The number of releasable licenses is registered in a first entity, the resource to be used being attributed and/or having withdrawn from it, by a second entity, a releasable license for use which is registered in the second entity and/or a license. In a synchronization step the difference between the number of licenses allocated for use since a previous synchronization step and the licenses released again in this time is repeatedly reported from the second entities to the first entity respectively, this difference being taken as a basis for reducing or increasing the number of releasable licenses registered in the first entity, and conversely the resultant number of releasable licenses is reported from the first entity to the second entity and is registered there as the number of releasable licenses.
