concentric cylinderACCESSORIES AND APPLICATIONSGeneric Container HolderThe Generic Container Holder is a Smart Swap option that can hold anycontainer with an outer diameter of up to 80 mm for characterizing materialswith rotors. This allows for quick off-the-shelf evaluation of materials, suchas paints and varnishes, creams, pasta sauce, etc., without creating largeshearing from sample loading. It also is an excellent platform for beakersor jacketed beakers.Flow Curve on Xanthan GumConcentric Cylinder geometries are useful for gathering viscosity flow curveinformation over a wide range of shear rates. An example is shown in thefigure for a Xanthan Gum solution. Five decades of viscosity are easilyobtained over six decades of shear rate. This system is also a powerfulalternative to parallel plate or cone and plate geometries for materialswith limited stability or prone to edge failure or rapid solvent evaporation.Xanthan Gum Solution in Concentric Cylinder100001001000Viscosity (Pa.s)100.010.010.0Shear Stress (Pa)1.00.100.0101.00.0010 0.010 0.10 1.0 10.0 100 1000shear rate (1/s)18
