To cover the full range of rheological properties, RheoLabQC and the MCR rheometer series offer a broad selection of measuring systems. The QuickConnect quick-fit coupling system allows one-handed connection of the measuring systems and ensures fast, convenient system changes without the use of a screwing mechanism. Toolmaster is the only completely contact-free automatic tool recognition and configuration system for measuring systems and temperature control units. The innovative optoelectronic technology, implemented in MultiDrive measuring systems, enables temperature determination without affecting torque sensitivity.
Key features
Concentric cylinder systems (DIN EN ISO 3219 and DIN 53019)*
Concentric cylinder (CC) geometries are commonly used for low-viscosity liquids but are also well suited for a broad range of samples – from water-like fluids to semi-solid materials such as creams. These systems are easy to fill, with a filling level mark inside the cup. Due to the large outer surface of the cup, the temperature of the sample can be easily controlled from the outside and fluids with low surface tension are prevented from flowing out. A special hood or a solvent trap helps to avoid solvent evaporation.
CC systems with a sandblasted or profiled surface prevent wall-slip effects. Disposable cups and bobs are also available for single use with hard-to-clean samples.
Double-gap measuring systems (DIN 54453)*
Double-gap (DG) systems in accordance with ISO/WD 3219-2 have a special geometry that provides for a large contact area between the sample and the surface of the geometry. This enables testing at high torque resolution, in particular low-viscosity liquids such as water. Advantages include the large surface area such a system exposes and also the good thermal stability. Turbulences occur only at very high shear rates.
Vane geometries and spindles, and Krebs spindles (ASTM D562)*
To determine relative viscosity values, you can choose from a wide variety of measuring systems. Vane geometries, for example, are suitable for measuring samples containing particles (>0.1 mm) and with a tendency to sediment (such as dispersions).
Vane geometries and spindles are available to suit different applications such as starch solutions or yogurt-containing particles. Krebs measuring systems (with a unit range from 40 KU to 150 KU) are specially designed for the paint, building, and mining industries.
Cone-plate measuring systems (DIN EN ISO 3219 and DIN 53019)**
Cone-plate geometries are suitable for all types of fluids. Only a small sample volume is required. However, their applicability to dispersions is limited to a maximum particle size (˂10 µm).
These systems generate consistent shear conditions and are easy to clean. They reach temperature equilibrium rapidly due to quick temperature adjustment. Accessories like a special hood or a solvent trap can be used to prevent solvent evaporation.
Parallel plate measuring systems (ISO 6721-10 and DIN 53019)**
Parallel plate systems are recommended for testing pastes, gels, soft solids, or highly viscous polymer melts. A relatively small amount of sample is required. Due to the adjustable gap, you can set various measuring conditions. It is also possible to test highly viscous samples (including uncrosslinked silicone), dispersions with large particles, gels with a three-dimensional superstructure, and soft solids such as cheese or elastomers.
