A rotorless rheometer measuring cure characteristics and viscoelastic properties of rubber compounds via oscillating die across an extended strain range, delivering comprehensive vulcanization data.
Product Information
The Bareiss MDR ultra sets a new benchmark in cure analysis — delivering fast, accurate characterization of rubber compounds under isothermal and non-isothermal conditions. Its ultra-rigid frame, sealed biconical dies, and advanced temperature management guarantee stable, repeatable measurements — fully conforming to ASTM, ISO, and DIN standards. Combined with the modern and user-friendly BareissOne software, it transforms complex curing data into clear, actionable insights for confident quality assurance.
