Rheology software.

Software has been developed for the company's rotational rheometers that is said to greatly expand testing capabilities, but also retains a simple user interface. In the viscometry and oscillation modes, a customized table is said to enable users to design tests with greater flexibility. In a flow curve test, traditionally the start and end values and the number of steps were specified, according to the company. Now, individual values of shear rate and interval time at each step can be pre-programmed. This is said to mean that just about any viscosity versus shear rate measurement can be replicated on the company's rheometer. In a frequency sweep measurement, the sampling rate can be changed during the actual test, enabling better resolution of the viscoelastic data, according to the company. This is said to be of particular benefit when studying subtle changes in phase angle for weakly structured systems. The oscillation test also has a rapid sampling option (partial wave analysis) to provide fast tracking of data for applications such as curing and gelation, according to the company. This enables discrete material transitions to be identified by collecting several points per second. (Bohlin Instruments)
