  • Patent number: 5720406
    Abstract: A throwaway arrangement of reaction containers each having the same shape and dimensions for bringing about temperature cycles in a liquid mixture contained within the reaction containers. Each reaction container having a first conical wall region, and a second cylindrical wall region which at one end forms the opening of the reaction container. The thickness of the first wall region is less than the thickness of the second wall region. The opening of the reaction container is adapted to receive a cover for closing the container in gas-tight manner when placed on the opening of the reaction container. To facilitate handling and access to the liquids in the reaction containers, the arrangement reaction containers is annular, and the closure of each reaction container can be pierced by a pipetting needle.
