Abstract
A cassette assembly () comprises a cover (), two cassette halves (A,B) and a slider () comprising multiple test chambers (). The cassette halves (A,B) comprise waste tanks () in fluid connection with reservoirs (), prefilled in one of the cassette halves (A,B) with test agents. The particular design of the cassette halves (A,B) enable forming predefinedvolumes of liquid to achieve predefined concentrations of the test agents in the reservoirs () in one of the cassette halves (A,B) and liquid in the reservoirs () in the other of the cassette halves (A,B). Gradients of the test agents can then be established over the multiple test chambers ().
