The invention relates to a fill-level measuring device for a laboratory cabinet device, for measuring a fill-level in a liquid container in the interior of the laboratory cabinet device, which detects the fill-level by comparing the measurement of two NTC temperature sensors, the first of which is arranged in the air of the interior and the second in the liquid of the liquid container.

Fill-level measuring device for a laboratory cabinet device

The invention relates to a measurement apparatus for measuring the concentration of a gaseous substance. The apparatus comprises a light source, a light sensor, and a housing comprising at least one first housing member having a low thermal conductivity. A light path is formed from said light source to said light sensor, wherein the light path passes through a measurement region within said housing. The light source is configured to emit light with a spectral distribution such that said light is absorbed by said gaseous substance. Said light sensor is configured to receive the light emitted by the light source after it has passed through the measurement region. The first housing member comprises a thermal shielding region facing said measurement region on its one side and said light sensor on its other side, and is configured to permit the passage of light.

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.

Apparatus and method for generating a tool motion

The invention relates to an actuator apparatus () for generating the motion of a tool, in particular for the work on biological cell material, which provides at least one electrically controlled actuator element (), a motion section (), at which a tool can be arranged and which is linked to the at least one actuator element, an electrical control device () for controlling the at least one actuator element, an electrical measurement device (), which is configured to perform a measuring method for measuring at least one electrical capacitance quantity of the at least one actuator element, wherein the capacitance quantity is usable to provide information on the status of the actuator apparatus. Further, a corresponding method for obtaining and utilizing said information on the actuator apparatus is provided.

Actuator apparatus with control device

System for generating the motion of a tool, in particular for the work on biological cell material, which includes an apparatus, the apparatus providing a tool section, at which a tool can be arranged, and at least one actuator element arranged to move the tool section, the system further comprising a system control device.

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.

Stacked array of reaction receptacles

A system for detecting fluids in a microfluidic component having at least one microchannel including a limitation wall which has two surfaces which, facing the microchannel in a transparent area, are inclined towards each other at an acute angle, with the system further including a photo transmitter and a photo receiver which are disposed outside the component and are directed to the inclined surfaces in the transparent area of the limitation wall in such a way that if a gas is waiting in the microchannel on the two surfaces, a light ray emitted by the photo transmitter impinges on the photo receiver following a total reflection on the two surfaces and, if a liquid is waiting in the microchannel, the light ray enters the microchannel on at least one of the two surfaces and, as a result, the incidence of light into the photo receiver is reduced or prohibited.
