Selecting a Geometry

Recommendations for selection of a geometry based upon sample type are as follows:

Sample Type

Geometry

Low viscosity
fluids, suspensions and emulsions

Large Diameter Parallel Plate or Cone Plate, Concentric Cylinder or
Double Wall Concentric Cylinder

Higher viscosity fluids, and thicker
suspensions and emulsions

Parallel Plates or Cone and Plate

Solids

Torsion Rectangular/Cylindrical

Polymer Melts and Soft Solids

Parallel Plates or Cone and Plate

Thermosetting Resins and other
Curing Studies

Parallel Plate. Disposable plates are available for curing studies or
other reactive materials.
