Product Overview
The MDR vario provides precise and reliable analysis of rubber compound curing behaviour through advanced moving die rheometer technology.
Designed for demanding laboratory environments, the system measures critical vulcanisation characteristics including torque development, curing kinetics, and material response during the transition from uncured compound to finished elastomer.
The extended strain range allows users to perform material-specific amplitude testing, improving measurement reproducibility and generating more meaningful cure data across different compound types.
The MDR vario's ultra-rigid frame, sealed biconical dies, and advanced temperature management system ensure stable measurement conditions and excellent repeatability while maintaining compliance with international testing standards.
Combined with the intuitive BareissOne software platform, the MDR vario enables efficient test management, data analysis, and reporting, helping laboratories make confident decisions based on accurate rheological information.
