A mixing device has a swing arm and securing arms, for receiving and securing a mixing capsule within the mixing device, connected to the swing arm. The securing arms include at least one moveable securing arm that is movably connected to the swing arm and at least one stationary securing arm that is fixedly connected to the swing arm such that the moveable securing arm is moveable relative to the stationary securing arm. An inertia mass acts via at least one of the securing arms onto a mixing capsule received in the securing arms.

Mixing device

A polymerization apparatus includes a support plate for supporting a workpiece to be polymerized and a hood comprising a light source for guiding light to the workpiece such that the light impinges on at least two sides of the workpiece. The hood is liftable relative to the support plate so as to allow access to the workpiece when in a lifted position. A heat source for heating the workpiece is provided. A control device controls the function of the polymerization apparatus. A method for operating the polymerization apparatus includes the steps of heating the workpiece to a desired temperature after switching on the light source, maintaining the desired temperature for a desired polymerization cycle time period, and subsequently shutting down the light source and the heat source for a final polymerization cycle time period.
