  Working Principles
Click to ViewThe Rapid Visco Analyser is a rotational viscometer that continuously records the viscosity of a sample under conditions of controlled temperature and shear. The ability of the RVA to suspend samples in a solvent, maintain them in suspension throughout the test, and apply an appropriate amount of shear to match processing conditions makes it particularly valuable in many process and research applications. The combination of shearing, heating and cooling, applied over time, creates a viscosity curve for the material.

  User Instructions
It is suitable for a variety of applications requiring accurate viscosity information, such as the testing of starch-based products for quality controlOpen the appropriate RVA method in TCW software or select the appropriate RVA method using the instrument keypad, accurately weigh sample and water using an electronic balance. Add first the water and then the sample into the canister, place a paddle into the canister, mix and push down any sample lumps. Slide the paddle into the RVA motor coupling. Depress the tower to lower the canister into the RVA and start the test. The viscosity of the sample will be graphed on the monitor.
