Goettfert Capillary Rheometer

Description

The Göttfert Rheotester 1000 and Rheograph 2003 are high-pressure capillary rheometers. These instruments are used to determine the flow characteristics and viscosities of thermoplastic polymers and rubbers.

Operating range

Pressure: 1 bar to 1000 bar
Shear rate: 0.1 to 175,000 /sec
Temperature: 25 to 500°C

Application

viscosity-shear rate data
extensional viscosity measurement (Cogswell or Moldflow scheme)
first normal stress difference (Gleissle scheme)
Bagley end-pressure loss correction
thermal stability
Mooney slip
slit die measurements
