  • Patent number: 10428299
    Abstract: A mixing device for mixing contents of a container has a support for supporting the container and a moving device connected to the support for moving the support and mixing the contents of the container. The support has a positioning device to position the container so that a removal side of the container is arranged substantially along a predetermined line of the support. The support is pivotable about a removal pivot axis to move the container into a removal position. The removal pivot axis is at an angle of over 0° to 45° to the predetermined line of the support so that the container can be moved from the mixing position by pivoting the support about the removal pivot axis into the removal position where the removal side is on a lower side of the container and inclined toward a removal region of the container.

  • Patent number: 10363528
    Abstract: A mixing and thawing device (1) has a rocker drive (2) and a bag holder (3) for holding a bag (7). The bag holder (3) has a base part (8) and a lid part (9) that enclose a holding space (10) for the bag (7). A heating element (11) is arranged in the base part (8). Thus, the holding space (10) is designed as a heat-insulating closed chamber. Interconnected intermediate spaces (14, 15) are arranged between the bag (7) and the base part (8) and between the bag (7) and the lid part (9). One or more flow generators (16) are provided to generate a circulating fluid flow (17).

  • Patent number: 10253290
    Abstract: A bioreactor arrangement has a bioreactor and an illuminating body for illuminating a medium in a reactor interior. The illuminating body has at least one emission surface via which light, reflected by at least one end surface into the reactor interior, is emitted. The bioreactor is formed as a container having a transparent wall. The illuminating body is outside the reactor interior, next to at least one subregion of the transparent wall. The illuminating body forms a support surface for the bioreactor with its emission surface. A shaking device has a reactor holder that can be in oscillated, for a bioreactor with a transparent wall. The reactor holder has a two-dimensional illuminating body, the emission surface of which forms a support surface for the bioreactor, via which light can be reflected into the reactor interior of the bioreactor.
