End point determination | The Caleva MTR Variable Mix Time test

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 a 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.
In this video, our technical expert Scott Humphries walk you through the Mixer Torque Rheometer's multiple addition test. Watch as he finds the optimum amount of binder to use to create a tablet or extrusion and spheronization granulation.
