These capillary rheometers can be used on a lab bench for Quality Assurance or in an R&D setting. Their primary structure is made up of two columns, so you know you'll get top-notch performance from it. They run experiments with an infinite number of steps at a constant shear rate or constant speed using a velocity ratio of 1:500,000 (equivalent to a piston speed of 0.0024 to 1200 mm/min). Meets ISO, ASTM and equivalent standards.
