The RHEOGRAPHES 25, 50, 75 and 120 are newly developed, user-friendly high-pressure capillary rheometers with a further extended shear rate range, higher test load (25, 50, 75 and 120 kN) and a wide range of add-ons and options.

The newly developed series of GÖTTFERT high pressure capillary rheometers is available with different test loads of 25, 50, 75 or 120 kN. The stronger versions such as RG75 or RG120 can achieve extremely high shear rates even with very high viscosity test material. Due to a unique and large variety of modular add-ons not otherwise available on the market, other material properties can be tested in addition to viscosity. It is possible to characterize all process-relevant material behaviors.

All high-pressure capillary rheometers of this series are available as single-, twin- or triple-barrel versions with different test barrel diameters. We also offer a large number of capillaries and other options that make it possible to adapt the machine perfectly to your application.

An essential improvement of this series compared to the previous generation is the much more accurate pressure measurement. This makes it possible to significantly increase the reproducibility and precision of the test results. Especially the extremely low pressures at very low shear rates can be measured perfectly now.

Due to these improvements in the low and high shear rate range, GÖTTFERT is able to distinguish itself considerably from the market standard.
