The present disclosure provides for a sensor system for determining a flow rate of a fluid flow within a fluid channel comprising an elastic segment arranged next to a rigid segment, wherein a first pair of electrodes is provided at the rigid segment and a second pair of electrodes is provided at the elastic segment of the fluid channel. The system further comprises a sensor unit for detecting a capacitance of the first and second electrode pairs, and a processing unit for calculating and monitoring a distance between the electrodes of the second electrode pair based on the detected capacitance of the first electrode pair and the second electrode pair, wherein the first electrode pair is in contact with the rigid segment and the second electrode pair is in contact with the elastic segment. Moreover, a respective method for determining a flow rate of a fluid flow within a fluid channel is provided by the present disclosure, as well as a use of the sensor system.

Flow rate sensor system, method for and use of such system for determining a flow rate

A device for the thermal treatment of test samples is presented. The device comprises a sample holder and one or more thermoelectric elements which are in thermal contact with the sample holder. The sample holder comprises at least two holding positions configured to hold test sample consumables. The sample holder comprises an internal working fluid and a hollow body with an inner bottom surface and an inner top surface connected to each other with a pillar. The pillar extends along a vertical axis perpendicular to the inner bottom surface and substantially in the middle of the distance between the at least two holding positions. A laboratory instrument and a method for the thermal treatment of test samples is also presented.

Device for the thermal treatment of test samples

A method to monitor and control the temperature of a sample holder of a laboratory instrument during execution of a temperature profile on the sample holder is presented. The laboratory instrument comprises a sample holder with high temperature uniformity and at least three identical temperature sensors. The measured actual temperatures of the sample holder are processed in order to determine if the execution of the temperature profile should be continued or aborted. Furthermore, temperature sensors which measure actual temperatures that do not fulfil certain requirements are excluded from further monitoring and controlling the temperature of a sample holder.
