Product news

Brookfield welcomes three new instruments into its touch screen family of rheometers: the RST-CPS Cone Plate Rheometer, the RST-CC Coaxial Cylinder Rheometer and the RST-SST Soft Solids Tester Rheometer. The new RST Series offers the quickest and most comprehensive capability for making rheological measurements, whether it’s single point viscosity for QC or complete flow curve analysis for R&D.

The RST Rheometers are unique because they operate in both controlled stress and controlled rate modes and can perform all of the following tests: viscoelastic modulus, yield stress, viscosity vs. shear rate profile, thixotropy calculation, creep behavior, recovery after flow, and temperature sensitivity. Every RST Rheometer offers the widest torque range available to handle the broadest range of sample materials (500 to 1 million dyne.cm). They provide exceptional versatility with the largest range of shear rates and Din spindle geometries. The sturdy, rugged design of the RST is ideal for use in R&D, working in the QC lab or on the production floor.

All RST models come with the standard option for 21 CFR compliance, including controlled user access and data integrity/security.

RheometryRheometers are used to measure the rheology of fluids, which is the flow of fluids in response to an applied force. The most common types of rheometer include shear rheometers (capillary, cone and plate and rotational cylinder) and extensional rheometers. Viscometers are similar to rheometers however viscometers only measure the viscosity of a fluid.Drug DeliveryDrug Delivery refers to dosage form, route of administration, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effect. Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. Rheology
