The invention relates to an apparatus according to the present invention for generating the motion of a tool, in particular for the work on biological cell material, in particular for performing ICSI, comprises at least one actuator element, an actuated member, a motion section, at which can be arranged a tool and which is linked to the actuated member, the actuated member being elastically deformable, the actuator element being linked to the actuated member such that an actuation by the actuator element elastically deforms the actuated member by a distance, which corresponds to a length change of the actuated member, wherein said length change causes said motion of the motion section. Further, a corresponding method for generating a tool motion is provided.

A method for the quantitative real time analysis of fluorescent samples is provided, at which each of the samples is excited to fluoresce by a sample individual light source () and the intensity of the light which is emitted by the samples is measured. For a highly precise measurement of even low light intensities for the purpose of reduction of the analysis time, each light source () is switched on and off-during a defined interval by a clocked pulse sequence of constant pulse frequency alternately. The measurement of the intensity of the emission light during these intervals is exclusively performed during the switch-on phases of the light, source ().

The invention relates to a method for photometrically investigating sample radiations of at least one sample, which are caused by the radiation of N emitter elements of at least one radiation element wherein said N emitter elements are emitting radiation during time periods which at least partially overlap, to detect the sample radiation of at least two samples as a sum signal during time periods which at least partially overlap and to evaluate the sample radiation of at least one individual sample from said sum signal.

Device and method for radiometric measurement of a plurality of samples

The invention relates to a laboratory apparatus for simultaneously carrying out reactions in a plurality of samples which are arranged in an array. The apparatus includes an illumination device, which emits illumination light onto the samples, a detection device, which generates a signal dependent on the light intensity of the light coming from the samples and which forwards the signal to an evaluation device, and a monitoring device for checking the functioning of the illumination device. The illumination device has a plurality of light-emitting diodes assigned in each case to one of the samples, and the monitoring device has electrical devices which can be used to perform an electrical functional check of the light-emitting diodes. The monitoring device is adapted to generate a signal when a functional disturbance of a light-emitting diode is ascertained.

Laboratory apparatus for simultaneously carrying out reactions in a plurality of samples

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.
