NEW MIXER TORQUE RHEOMETER (MTR)

Gain a deeper understanding of your granulation to accelerate formulation development & ensure production quality 

Replace the subjective 'hand squeeze' or 'snowball' test with precision data provided by the Mixer Torque Rheometer (MTR). Remove the guesswork and let the MTR accelerate and enhance your research and development experiments and maintain quality and protect yields in your production line.

Designed to measure and characterise wet granulation properties for tabletting, extrusion, and spheronization outcomes, the MTR helps you to reduce material waste, save time, save money and increase your Return-On-Investment throughout the product lifecycle.

    Introducing the new Mixer Torque Rheometer (MTR)

    The new MTR builds on many years of experience in providing highly accurate data for groundbreaking studies across multiple industries. Designed to optimise liquid-to-powder ratios, provide indications of granule strength and reduce material waste, the MTR can define a robust design space to speed up your formulation development, support scale up, and ensure quality and yields are maintained in production environments.

    • Compatible with liquid binders containing a suspension
    • Pump priming function for consistent results from the first binder addition step
    • Binder calibration kit to quickly optimise the machine for specific binder densities
    • Load cell calibration kit with certified weights as standard
    • Includes pause option and image capture

    How it works

    Using just 15-40g samples, the Mixer Torque Rheometer (MTR) provides exhaustive and accurate data about your granulation by precisely measuring the torque generated during the mixing process. 200 data points are recorded every second to give extremely precise results. The resulting data allows you to predict and optimise liquid-to-powder ratio and the robustness of your formulation.

    The MTR also provides a quick quantitative method for benchmark and comparison during scale-up or production.

    With an intuitive user interface and full control over process parameters you can make more informed decisions faster with quantitative data displayed as it happens. Alternatively you can export your data for further investigation and deeper insights.

    Understanding Wet Granulations: The MTR’s Three Key Tests Explained

    The Mixer Torque Rheometer performs three experiments that help to optimise your wet granulation by providing precise, repeatable data.

    How to use the Mixer Torque Rheometer for:

    Tabletting Formulations

    Skip the lengthy trial and error stage of establishing liquid to solid ratios and optimal mix time to support reliable die filling, reduced segregation, and stronger tablet formation. The MTR is a vital companion for speeding up formulation development for tablets - especially when the active pharmaceutical ingredient (API) is expensive or in short supply.

    Extrusion and Spheronization

    Replace the subjective 'hand squeeze test' and quickly identify the optimal amount of liquid binder to powder ratio, and mix time needed to define your design space for successful extrusion and spheronization outcomes.

    Scale Up

    Ensure a seamless transition from laboratory-scale experiments up to pilot, batch or continuous production. The MTR can help you achieve consistent results as you scale, eliminating concerns about material differences between lab and production scale equipment and performance across different brands.

    Production Quality Control

    Use the MTR to establish and maintain rigorous quality control standards, leading to enhanced product quality and usable yield. As a line side tool, the MTR can help you ensure product consistency across different operators, different lines or batches and even different production sites. Identify issues quickly to avoid costly downtime and wasted batches.

    Powder Characterisation

    Researchers and manufacturers can use the detailed insights provided by the MTR to optimise their powder formulations, leading to improved process efficiencies and a deeper understanding of powder behaviour during processing, to achieve high-quality products.
