Mixer Torque Rheometer
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.

Machine Overview
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. ā

Determine the Optimum Powder to Binder Ratio
Multiple Addition Test
Binder liquid is added to a dry powder mix and the consistency is measured as the mixing and addition of binder progresses.
ā
The consistency of the mix is measured at regular periods so that the relationship between the amount of liquid binder added to the mix and the consistency in the resulting formulation can be accurately shown.
Variable Mix Time Test
How Long Should I Granulate my Materials?
It is well-known that a minimum amount of mixing is required to ensure consistent and repeatable product characteristics. What is often less considered is the possibility of over-mixing the product so that the characteristics of the resulting formulation undergo a change. It is important to understand this and to have data to show what is likely to happen with excessive mixing. The Mixer Torque Rheometer will give you this data. This type of test is again used in formulation development but more generally in scale up to production from the laboratory and also it has been used to solve production issues as they arise.
Ensuring Consistency During Scale Up
A direct consistency measurement of a small sample (generally around 40 g) taken from a process as it is ongoing. This allows for accurate comparisons to be made quickly, accurately, and repeatable way.
