RHEOMETER vs VISCOMETER
A rheometer provides much more insight into your product properties
A viscometer is well suited as a QC tool - simple to use and relatively inexpensive to purchase, maintain, and operate. A viscometer typically provides a viscosity result under a single set of defined conditions that may provide insight into a relatively small rheological properties window.
In contrast, a rheometer is a powerful R&D and problem solving tool that performs an array of rotational, oscillational, and vertical geometry movements to probe a broad range of rheological responses to applied forces and conditions (stress, strain, shear, temperature, amplitude, frequency, tribology (friction), and vertical compression/pull-away and surface tension). These properties include, but are not limited to stringiness, stickiness, adhesion, cohesion, pumpability, suspension stability, texture, thixotropy, structural characterization, spreadability, and physical and thermal stability.
The following sections describe in more detail only some of the primary rheology measurements and their applications that RTS offers to help you better understand your product properties. RTS provides rapid turn-around, are very flexible and often perform investigative one-off analyses to meet your particular rheological needs.
