  • Patent number: 10031051
    Abstract: A device for collecting a sample and for depositing the sample in a sample-receiving port of a measuring apparatus comprises a first connection element (8) with three connections for fluid, and a second connection element (7), and a hollow needle (5) for collecting and depositing the sample. A first feed line (9) for a first washing liquid is connected via a first pump to a first connection for fluid of the first connection element (8). A second feed line (10) for a second washing liquid is connected via a second pump to a second connection for fluid of the first connection element (8). A connection for fluid of the second connection element (7) is connected to the third connection for fluid of the first connection element (8), and the second connection element (7) is connected to a dosing device (1) and to the hollow needle (5). A valve (2) is arranged between the third connection for fluid of the first connection element (8) and the second connection element (7).

  • Publication number: 20060261964
    Abstract: A safety device for laboratory work, especially for fluid chromatography systems includes a level measuring arrangement which is connected to a tank and generates an alarm signal upon detection of a certain liquid level in the tank. The level measuring arrangement is also connected to at least one laboratory working surface and also produces an alarm signal when liquid is detected running over the at least one laboratory working surface. The level measuring arrangement is connected to a monitoring device embodied as a power supply unit in the form of a liquid control interface (LCI), the monitoring device containing a plurality of safety circuits and introducing a time-delayed circuit interruption when an alarm is generated by one of the safety circuits.
