MDR Elite 6300

  • Direct drive & “Dyna Pro” software enables to automatically set oscillation angle thus removing the need of physical adjustment/ replacement of spacers and eliminating the requirement for re-calibration.
  • Measures isothermal & non-isothermal cure properties (Non- isothermal is optional as it is available only with cooling option).
  • Advanced Symmetry of the upper crosshead with a four post design giving a rigid and sturdy system.
  • Choice of Unit systems: Torque Units: dN.m,, or Nm & Temperature Units in either ◦C or ◦F.
  • Acute Die Alignment giving an excellent die cavity sealing ensuring high repeatability.
  • Uniquely designed heater to reduce temperature gradients and improve temperature recovery.
  • The test frame of the equipment is extremely rigid, ensuring accurate and compliance-free data.
  • The equipment boasts unmatched precision, accuracy, and reproducibility of data. It achieves this through the use of a robust and field-proven torque transducer that guarantees high stability and reliable torque measurements.
  • The use of pneumatic locking cylinders further enhances the equipment's performance, as it ensures repeatable sample sealing.
  • The equipment comes equipped with powerful and intuitive user friendly Software, which is available in multiple languages.
  • Additionally, the equipment allows for user calibration and user-replaceable seals, which not only increases its lifespan but also reduces maintenance costs.
  • The combination of these advanced features makes this equipment a top choice for those in the industry seeking reliable and accurate results.
  • The device offers over 100+ different process parameters like: ts1, TC10, TC50, TC90, S’min, S’max, scorch time, cure rate, and viscoelastic properties including: G’, G”, G*, S’, S”, S*, tan δ, η’, η”, η*


  • The MDR employs a direct drive motor that enables precise deformation of the sample.
  • This Direct Drive system ensures that accurate and consistent deformation is always applied to the sample.
  • The accuracy and precision of rheological or dynamic measurements rely heavily on the accurate application of constant deformation at a specific rate, step or periodic interval.
  • Hence MDR can provide a highly reliable and repeatable data for various testing requirements.


  • The Standard Air Cooling System is designed to enhance temperature stability during testing.
  • By blowing air at room temperature on both the cavities at 5˚C to 10˚C ambient air, the system can speed up temperature changes above ambient conditions and maintain stable temperatures near room temperature.
  • This allows for more precise and reliable testing results, especially in applications where temperature control is critical.
