Abstract: A device which has a deliverable sensor, a container for receiving a liquid, a container environment and a signal processing circuit, the input side of which can be connected circuitry-wise to the sensor. The device is designed to perform a capacitive liquid level measurement in normal operation using the sensor, wherein a threshold value can be predefined for the signal processing circuit for normal operation. The device has a classification module which can be connected with an input side or line connection circuitry-wise to the sensor, is designed to make a capacitive measurement of the liquid in the container using the sensor and can be connected circuitry-wise to the signal processing circuit in order to trigger the specification of a threshold value using the sensor for capacitive measurement of the liquid.

Abstract: An inlet valve charges an inner chamber with liquid and has a first axis and an inlet opening with a tool that automatically recloses. The inlet valve has a valve body with a blocking element, and a pressing part; a valve space enclosing the valve body at least partly; a spring mechanism and a sealing element. An open passage region opens into the liquid passage of the pressing part and into the valve space. The spring mechanism presses a sealing surface of the blocking element against the sealing element in a closed position of the valve body. The valve body of the inlet valve can be brought to an open position by pressing the pressing part against the resistance of the spring mechanism. Chamber systems and sample containers with such inlet valves are also disclosed.

Abstract: An inlet valve charges an inner chamber of a system or sample container with liquid and has a first pipetting axis, an inlet opening, it supplies liquid by a laboratory pipette that is automatically reclosed and also has a valve body with a blocking element, a pressing part and a throat, a valve space enclosing the valve body at least partly near the throat, a spring mechanism and a sealing element. The throat connects the blocking element to the pressing part and has an open passage region which opens into the liquid passage of the pressing part and into the valve space. The spring mechanism presses a sealing surface of the blocking element against the sealing element in a closed position of the valve body. The valve body can be brought to an open position by pressing the pressing part against the spring mechanism.
