a cuvette module comprises a cuvette carrier and a cuvette held by the cuvette carrier . an intermediate chamber is formed in the cuvette carrier . the cuvette carrier comprises an electrically conductive plastic material . the cuvette has a different material than the cuvette carrier and the wettability of the cuvette carrier is greater than the wettability of the cuvette . a method transfers a predetermined amount of liquid from a transport container to a cuvette , employs a cuvette module . the method makes it easier to check whether the intermediate chamber still contains a sufficient amount of liquid .
