Capillary Rheometer RG20-120

▶️ Increased shear rate range

The 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.

Highlights:
- 20–120 kN test force
- Single- or multi-barrel system in 9.55, 12, 15, 20, 25, or 30 mm versions – custom dimensions also available
- Speed range
RG20: 0.0001 – 30 mm/s
RG25-120: 0.00004  – 40 mm/s (1:1000000)
- High dynamic acceleration of the test piston (0 to 40 mm/s in 0.6 s)
- Position measurement with high-resolution encoder
- Temperature range up to 400 °C (optional 500 °C)
- Automatic signal resolution of 0.005% of the pressure transducer’s nominal value
- Extensive range of add-ons for advanced material characterization
