Abstract: The invention relates to closure, in particular for a nutrient medium container, wherein a lower part can be covered by an upper part, wherein the lower part and the upper part can be locked against each other by means of at least one locking receptacle and at least one locking part by rotating the lower part and the upper part about a longitudinal axis, and wherein the locking receptacle has a receptacle groove that is covered by a shoulder and that extends perpendicularly to the longitudinal axis, in which receptacle groove the locking part engages, wherein the shoulder has at least one ramp surface extending at an angle from the longitudinal axis on the outer face of the shoulder facing away from the receptacle groove.
Abstract: A bioreactor has a stirrer shaft that is driveable by a drive and on which a stirrer element is positioned. The position of the stirrer element is determined by a stirrer installation aid. The stirrer installation aid has a free end with an abutment surface on which the free end of the stirrer element abuts. The stirrer installation aid is designed as a sleeve that comprises a slot extending between the axial ends of the sleeve. The slot is delimited by opposite flanks of a wall, and the sleeve is placed on the stirrer shaft. The stirrer installation aid can be pulled off laterally from the stirrer shaft. A method for installing the stirrer element on the stirrer shaft arranged in the bioreactor also is provided.

Abstract: A mixing container has a wall enclosing a mixing volume, an anchor fixed at the wall of the mixing container inside the mixing volume, and at least one mixing plate movably mounted to the anchor to allow a relative movement of the at least one mixing plate along a stir direction perpendicular to the extension of the mixing plate. Each of the at least one mixing plates is provided with at least one magnet.
Abstract: A mounting (28) for a side panel (26) of a weighing machine (10) has two rails (30, 32) which lie opposite one another and extend substantially parallel to each other. The side panel (26) is guided between the rails and thereby moves between a closed position and an open position. A stop (46) on the first rail (30) co-operates with the side panel (26), such that the completely open position is defined, and the second opposite rail (32) lies opposite the first rail (30) with such a spacing that the side panel (26), when being located in the open position, can be moved away by lifting of the rear edge (29) of the side panel (26) over the stop (46), but the opposing front edge (27) of the side panel (26) cannot be lifted or can only be lifted insignificantly.
Abstract: The present invention relates to methods for purification of Vaccinia viruses (VV) and/or Vaccinia virus (VV) particles, which can lead to highly pure and stable virus preparations of predominantly biologically active viruses. The invention encompasses purifying a virus preparation in a sterilized way with high efficiency and desirable yield in terms of purity, biological activity and stability, aspects advantageous for industrial production.
