Abstract: A dispenser for powdery substances contained in a separate package that has a container part with removable container cover, wherein an aspirated air flow is further sucked predominantly through the container part after removal of the container cover from the container part, such that two air flows entering through slits in a lid that can be pivoted around a pivoting axis evacuate the container part from its two ends, and after merging enter a vortex chamber upstream from a mouthpiece. Outside air inlet openings for a third air flow are formed in a housing part covered by the lid in a radial extension to the pivoting axis.

Abstract: A transfer cannula for sterile transfer of fluids to powders or fluids to fluids from a first receptacle into a second receptacle has two tube sections running in the same direction which have different lengths in the longitudinal direction of the tube sections, the longer tube section terminating in an insertion tip. The tube sections are rigidly connected to a coupling wall surrounding the tube sections in a cylindrical manner. The coupling wall has a cutout which extends as far as an end edge of the coupling wall and in which, when viewed from the side, an insertion tip of each tube section is exposed. The coupling wall projects beyond the insertion tip in the direction of the longitudinal extent of the tube sections, and the cut-out widens in a corresponding V-shape at the end edge.

Abstract: A dispenser for discharging an in particular granular or powdery substance by blow-out, has a blow-out duct, and a suction line opening into the blow-out duct for sucking the substance into the blow-out duct. A positive air pressure can be built up in a duct section arranged upstream of the blow-out duct and closed in the direction of the blow-out duct by a valve opening in a pressure-dependent manner, for pressure-controlled formation of a blow-out stream in the blow-out duct. A method for emptying a substance reservoir having a freeze-dried substance sucks the substance out of the substance reservoir, using a suction air stream opening into a blowing stream, and discharges the substance. A sucking/blowing dispenser is used for emptying a substance reservoir having a freeze-dried substance.

Abstract: A vessel, in particular for receiving small quantities of liquid, for example for receiving analysis samples, has a vessel body which has a small diameter relative to a vessel length. The vessel body has a longitudinal axis and an opening which can be closed by a screw cap. This vessel is advantageously easy to handle with respect to closing the vessel. The screw cap can be secured by plugging the screw cap in the direction of the longitudinal axis in order to close the opening using an adapter part to which the screw cap is screw-fastened; afterwards, however, the opening can only be released by unscrewing the screw cap.
