We used the Brookfield DV3TRV Rheometer, with EZ-Yield™ software for automated instrument control and data acquisition. Spindle: V-73 Vane Spindle, Immersed to the Primary Immersion Mark Results over the range of shear rates were all on-scale between 10 and 100% torque. This behavior is known as “shear-thinning”. Representative data from the analyses are shown in Figure 2.įigure 2 shows that the viscosity of the dishwasher detergent decreased as the shear rate increased. The Small Sample Adapter can be an extremely valuable accessory, especially if you would like to use much smaller samples than required to perform Method 1. A syringe was used to measure 10.4 mL of the sample and dispense it into the chamber. Three different samples were tested to ensure repeatability. Our test temperature of 25☌ was maintained by connecting the Small Sample Adapter water jacket to a Brookfield TC-550AP Programmable Refrigerated Bath. In our example, we used a Brookfield DV3THA Rheometer with Rheocalc™ software for automated instrument control and data acquisition. The Small Sample Adapter may be used with various Brookfield Viscometers or Rheometers. Spindle: SC4-27 Spindle with 13RPY Sample ChamberĪccessories: Small Sample Adapter, TC-550AP Programmable Refrigerated Bath Note that all three curves lay on top of one another, which shows excellent repeatability.įigure 1: Dishwasher Detergent at 70°-72☌ This behavior is known as “shear-thinning.” Results over the range of shear rates were all on-scale between 10 and 100% of fullscale range torque. Representative data from the analyses are shown in Figure 1 which shows that the viscosity of the Dishwasher Detergent decreased as the shear rate increased. Each trial was run in a new portion of the sample. Three trials were run to ensure repeatability. We used an HB-3 spindle immersed to its immersion mark. We ran our test at room temperature (70-72☏) in a 600 mL beaker. We used a Brookfield DV3THB Rheometer with Rheocalc™ software for automated instrument control and data acquisition. To be used in a dishwasher to help clean dishes.
