respons®940 is an automated random access clinical chemistry analyzer and offers a constant throughput of minimum 400 tests/h, independently whether a mono- or two component reagent is used. Including the optionally available ISE module with additional 240 test/h the total throughout increases to 640 tests/h.


Together with modern software features, pre-programmed applications and carry over evasion lists, respons®940 analyzer delivers high quality results for a broad parameter portfolio.
Due to durable quartz cuvettes, low reaction volume and maintenance free photometer, this analyzer offers the economic use and reliability required in small to medium sized labs.
