Karlsruhe / Germany (September 12, 2006) Thermo Electron Corporation, the world leader in analytical instruments, has introduced a new measuring cell for HAAKE rheometers designed specifically to test construction materials. Rheological testing of construction materials can be subject to inaccuracy due to formation of slip films or local inhomogeneities in the sample tested. Thermo Electron's new construction material cell provides a wide range of wall profiling options to counteract these effects. Unlike conventional measuring cups with fixed profiling heights, the new HAAKE construction material cell allows the profiling ribs to be changed as needed.
