The invention relates to a tempering apparatus for tempering a sample comprising: at least one tempering block configured for receiving at least one sample, at least one tempering device arranged for tempering the tempering block, at least one temperature measurement device assigned to the tempering device, at least one control loop to which the tempering device and temperature measurement device are assigned to, at least one control device configured for control of the tempering of the tempering block, wherein the tempering apparatus comprises at least two temperature measurement devices assigned to the control loop, and that to the tempering apparatus a testing device for performing a test method is assigned to, wherein the testing device comprises a signal-connection to at least one of the at least two temperature measurement devices, such that at least one testing quantity of the tempering apparatus is detectable, which characterizes the operational status of the tempering apparatus.

Tempering apparatus with testing device and method for testing a tempering apparatus

A device for mechanically decollating cells from a cell composite, particularly a shear rotor, a cell isolation unit including such a shear rotor and a method for decollating cells from a cell composite. The aforementioned device includes a rotor having a rotor wall, which is concentrically arranged in a receptacle. A rotor seat is connected to a motor and to which the rotor can be fixed in a detachable manner. A rotational movement of the motor can be transmitted to the rotor by means of the rotor seat. The rotor tapers longitudinally towards the bottom of the receptacle so that different circumferential speeds of the rotor can be transmitted to a liquid sample in the receptacle via the rotor wall.

The invention relates to a method for testing of a tempering apparatus, wherein the method comprises the following steps: starting of the method; operation of at least said first tempering device for the duration of at least one first period from at least one first time; detection of at least one measurement temperature from said at least one first temperature measurement device, which is assigned to said first tempering device, at least at a second time; determining at least one first testing quantity of the tempering apparatus by using said at least one measurement temperature; and comparison of said first testing quantity with one reference quantity.

A configuration of mini-volume reaction receptacles () of which the receptacle housings () each enclose an elongated chamber () of which the ends are connected to apertures () formed in the receptacle housing. The receptacle housings have identical base surfaces and have a small height relative to the base surface, and are stacked on one another while their base surfaces are mutually aligned. At least one aperture of a receptacle housing communicates with at least one aperture of a vertically adjacent receptacle housing, as seen in the direction of stacking. The receptacles () are mechanically interlocked in a direction transverse to the direction of stacking and can be plugged one into another. Each receptacle housing defines at least one aperture () at its top side that is accessible to a pipette.
