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.
Extended strain range
Allows material-specific amplitude testing for improved reproducibility, resulting in more accurate and meaningful cure data.
FT-Rheology as Standard
Captures torque and strain harmonics in every test, making measurement artifacts immediately visible for more transparent analysis.
Air cooling as Standard
Reduces cooling times to increase testing efficiency while enabling precise non-isothermal temperature control.
Ultra-rigid test frame
Minimizes instrument compliance to ensure accurate torque and strain measurements, delivering reliable and reproducible results across all material types.
Pure polymers, polymer blends, uncured rubber compounds, in-situ compounds, thermoplastics, liquid silicone rubber (LSR), Thermoplastic Elastomers (TPE), recovered carbon black (rCB) compounds

Traceability refers to the ability to monitor the origin, progress and history of our products, calibrations, processes, or measurements. This means that all steps and parameters that contribute to the creation of our products must be documented and traceable.
Traceability ensures the transparency, integrity and reliability of data and enables the checking of quality standards. It plays a crucial role in error detection, quality control and ensuring compliance with legal requirements and our quality standards.
DAkkS-accredited laboratory since 1996 – Calibrations meeting the highest requirements and global standards.
Calibration reminders – We automatically remind you of your next calibration.
Service packages – Accredited calibration including maintenance and repair at a fixed price. Everything from a single source.
Trust Bareiss for reliable calibrations and accurate measurement results.
Benefit from our experience as a manufacturer and accredited calibration laboratory.

Bareiss recommendation: Laboratory conditions according to DIN ISO 23529
We are happy to answer any questions you might have about hardness testing!
