Biotech, Medical Device and Pharmaceutical Rheology & Viscosity Testing

Rheology and viscosity behaviour play a crucial role in the processing and performance of pharmaceuticals, medical devices and other biotech products. Our expert rheology testing and profiling services can inform the formulator or process developer on key product attributes throughout the development, manufacture and application of a wide range of products and materials.

Our advanced research rheometers and viscometers are able to quantify a range of product characteristics across parameters and conditions biotech, medical and pharmaceutical products will encounter.

We can help with:

Quality Control: Brookfield Viscosity Test Methods

For quality control needs, single-point Brookfield viscosity testing is the norm. However “Brookfield viscosity” is not a single established protocol but a collection of disparate instrument, accessory and method combinations. As pharmaceutical products are virtually all non-Newtonian liquids or semi-solids, viscosity is not always a simple matter and the correct choice of viscometer, spindle & speed, sample handling and container becomes crucial for the extraction of relevant and repeatable results.

We can provide expert method development and validation, sample analysis and training and advice to help ensure you gain the Brookfield viscosity results most relevant to your needs.
