One MDR tests one sample at a time, and that pace sets the limit for your whole lab. The patent-pending Premier MDR DUO puts dual dies in a single instrument, so you double throughput without doubling your bench space or your investment.
Testing capacity with dual dies
Instrument to house, run and maintain
Combined torque limit (212 dNm per head)
Maximum test temperature
Double testing capacity with a dual-die setup, cutting lead times and boosting productivity.
Lower capital cost by combining two testing units in one device.
A compact, patent-pending design minimizes bench space and optimizes lab layout.
One device means less maintenance and simpler operation.
When cure testing backs up, batch releases are delayed and no one is happy. Expanding capacity used to mean buying a second instrument, giving up bench space and spending double the capital. Not anymore.
The MDR DUO is built on the exact same platform as Alpha’s industry-leading MDR, so you keep the speed, precision and reliability you count on, while increasing capacity without a second machine.
Take a closer look at the dual-die design, controls and workflow in our interactive virtual demo — no appointment needed.
Dual dies let you test two samples at once, reducing lead time.
Lower upfront and maintenance costs, using the same certified Alpha OEM parts as the MDR.
Custom designed and manufactured to withstand any continuous production environment.
From the team that invented the moving die rheometer, backed by 60+ years of rheology expertise and approachable scientists and engineers.
Uptime is critical. A dedicated global service team is ready to help with calibration or repair.
Available as a basic DUO or configured with sample automation for even higher throughput.
