Goettfert Capillary Rheometer Testing Services

How Our Lab Uses the Goettfert Capillary Rheometer

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.

Common Applications

  • 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

Operating Ranges Offered

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

Get Started

  1. Share your requirements

    Tell us about the material, application, environment, and any method, standard, specimen, or conditioning constraints.

  2. Confirm the approach

    We’ll align the appropriate method, specimen requirements, and deliverables to your objectives, then provide a quote and test plan.

  3. Submit your PO and materials

    Send the purchase order and arrange delivery of materials or specimens so the program can move into scheduling and execution.

  4. Receive your results

    You’ll receive an engineering test report with digital data delivery, along with any agreed raw data or method-appropriate outputs.

    Typical turnaround for most testing is five business days. Longer-duration programs may require more time.
