Abstract
Official abstract text for this publication.
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.
