Abstract: A mounting means is provided for mounting a device comprising at least one mounting shield, a pivot bearing arranged in the mounting shield and a rotor mounted perpendicularly in the pivot bearing, an axis of rotation of the rotor being oriented substantially perpendicularly when the device is mounted on the mounting means, and the mounting means having resilient properties. In one embodiment, the resilient properties of the mounting means are direction-dependent, in particular orthotropic. As a consequence of the direction-dependent resilient properties of the mounting means, oscillations excited by a rotary movement of the rotor strike a mounting, the pivot point of which does not coincide with the axis of rotation of the rotor, but is set apart therefrom. This makes it much more difficult to excite the mounting means to form unstable oscillations, so that such oscillations are effectively damped.
Abstract: The invention relates to a swing-out unit for a centrifuge, with the swing-out unit comprising sample vessel recesses and being insertable in a centrifuge rotor head to be swivelable about a swing-out axis, with the axes of at least two sample vessel recesses being arranged in a skewed manner with respect to one another. As a result, more sample vessels can be inserted in a swing-out unit than was previously possible with limited overall space.
Abstract: The invention relates to a centrifuge cup, which has a container and a cover. The cover has a lever including a guide element in each case on opposing edge areas thereof. The guide elements are able to be introduced into an associated guide path of the container by pivoting the lever. The guide elements are implemented in such a way that in a closed state of the cover with the container, a clamping force (F) having vertical force component (Fy) and horizontal force component (Fx) is provided at a contact point or a contact line of the guide elements with the particular associated guide path.
Abstract: The invention relates to a cover closure for housings of laboratory devices and the like, in particular for centrifuge housings, in which a cover hook is engaged by a closure hook and brought into a closing position, and the closing and opening movement of the closure hook essentially being caused by an eccentric in connection with a crank guide and a guide path.
Abstract: The invention is relative to a climatic cabinet with a door, a utilization space, a specimen storage device, an inner transport device and a transfer opening. A buffer specimen storage device and an outer transport device are arranged on the outside in front of the transfer opening. The outer transport device establishes a transport connection between the buffer specimen storage device and the transfer opening by which a specimen can be brought between the buffer specimen storage device and the inner transport device. The invention has the advantage that the dwell time of the blade in an area with outside temperature is restricted to a minimum, as a result of which an ice-free transfer of specimen slides can be carried out even given a high transfer frequency and great differences of temperature and of atmospheric moisture.

Abstract: The present invention relates to a rotor for laboratory centrifuges, the rotor including a rotor housing that is open to the top and at least one recess for taking up centrifuge containers, with the recess being formed in the peripheral area of the rotor as a concentric, circumferential ring trough having an inner wall and an outer wall and with the ring trough being stiffened in a spoke-type manner in such a way using centrifuge containers that are distributed radially and over the circumference of the ring trough that the centrifuge containers support the inner wall and the outer wall rigidly against one another. Furthermore, an adapter for receiving a sample container and for use in such a rotor is suggested.

Abstract: The invention relates to a shaking incubator with at least one specimen storage device comprising several superposed specimen storage spaces. A shaking unit comprising a specimen storage position, a shaking platform and a base unit is arranged in at least one specimen storage space. The invention makes it possible to shake different specimens, located in the same specimen storage device, individually and independently of each other under incubator conditions.

Abstract: The present invention relates to a fixing device of a cover for a centrifuge rotor, a receiving chamber of the centrifuge rotor, which is driven using a drive unit, for receiving samples to be centrifuged being closable aerosol-tight using the cover. The fixing device is provided with an opening so that the drive unit is accessible through the fixing device and the cover without removing the cover. The present invention has the advantage that the rotor may be removed from the centrifuge and the rotor remains closed aerosol-tight at the same time. In addition, simple, one-handed operation is made possible.
