Abstract: The invention concerns the tamper-evident sealing (10) for seals (12, 14) of at least two nozzle-shaped ports (16, 18) of a container (20) such as infusion solution pouches. In order to achieve a secure sealing, while being easy to apply and with minor material use, it is intended that the tamper-evident sealing (10) is implemented as a ribbon-shaped shrink wrap that joins the ends (28, 30) of the ports (16, 18) and encompasses the seals (12, 14).

Abstract: The invention relates to a method and an apparatus for determining product-specific quality parameters of liquid, especially liquid (14) containing alcohol and held in a container (12) such as a bottle or can, the quality parameters being determined by means of sensors (22, 24, 26). To enable performing measurements with simply provisions and without complicated specimen preparation, and avoiding cross-sensitivities, it is proposed that the quality parameters of the liquid are determined under the conditions prevailing in the container, and liquid is initially delivered, under the pressure prevailing in the container, to a temperature unit (32) and adjusted to a temperature that corresponds to that of the sensors, and is then delivered to the sensors.

Abstract: To permit flexibility in chemical testing steps, a plurality of automatic chemical apparatus units are arranged in modular form, each unit including a main sample receptacle transport conveyor to move the receptacle holding a sample to be tested in a main transport path, a plurality of test and treatment containers being associated with each unit, and a sampling transfer station is located to extract a sample of test substance from the sample receptacle and introduce it into one of the test and treatment containers, which test and treatment container is then moved in a separate test and treatment conveyor path along a plurality of testing and treatment stations until the entire analysis of the removed sample is completed, at which time a new sample receptacle is moved along the main path to the sampling transfer station for introducing a new sample into a subsequent test and treatment receptacle.

Abstract: A valve ahead of a continuously running exhaust pump allows air to be sucked through the piping of a burette from the intake capillary and, after the capillary is lowered into the input sample vessel, a quantity of the sample liquid flushes out any remaining traces of a previous sample. After the necessary small quantity of the sample liquid has been thus pulled into and out of the burette, the valve is closed and a piston with a conical head fitting right into the burette draws in a measured quantity of the sample from the input container and then discharges it into the output container. The vertex of the piston is flattened so that the channel through the burette head will not be closed off when the piston is driven all the way into the burette head.
