Read MorePremier MDR – Moving Die Rheometer
Alpha continues to lead the way from the start of a revolution in rheology science to now.
This is not our first MDR.
In the beginning… well, actually not that long ago, but still a good while… The Oscillating Disc Rheometer (ODR) was not only the instrument of choice, it was the only choice. And it was limited to about one test. That’s why the engineers and scientists at Alpha Technologies (then known as Monsanto Rubber Chemicals) got to work and changed an industry. They invented the Moving Die Rheometer – the MDR: the workhorse cure meter for rheology testing in rubber and polymer plants worldwide.
Today the Premier® MDR introduces new technology that delivers data with the highest consistency and long-term stability, compared to all other moving die rheometers. Premier MDR delivers reliable, repeatable data, batch after batch meeting ISO 6502 and ASTM D5289 standards and requirements. Repeatability also means your data is consistently reproducible from instrument to instrument and factory to factory, worldwide. Your data doesn’t shift just because your time zone does.
Premier MDR is custom-designed and manufactured to withstand any continuous production environment. In fact, many of our early MDRs are still on the job 20, 30, 40 years later. That’s why Alpha is trusted by more top tier rubber and polymer manufacturers than any other brand.
“There are a lot of reverse engineered copies of Premier MDR in the field. What they lack is our proprietary design and engineering, our high-performance electronics, and our commitment to traceable standards. That’s why they are priced lower, and we’re okay with that. Our competitors know what their instruments are worth.”
– John Dick, Alpha Technologies Rheology Fellow
How to Compare Premier MDR with all the others.
Stiffer seals with low friction to prevent slippage and leakage and ensure no loss of signal. Plus, they last longer.
Oil saturated thrust bearings that last longer without greasing for overall lower maintenance costs.
Standard pressure transducer allows measurement of foam performance to determine if the pressure changes through the measurement. This enables you to optimize your formulation and reduce errors.
Separate touchscreen user interfaces – Workbench for instrument management and Online Manager for data analysis. Our custom electronics give you true multi-tasking. Unlike sluggish PLCs used by others, there’s no waiting for the test to finish before being able to review data.
Torque standards you can trust. Alpha is committed to traceable torque standards that make sure your instrument is accurately calibrated. Others use cheaper torque standards (that they don’t like to hand out) that have an unacceptable margin of error and need fudge factors to make them come out “right.”

Options that expand the capabilities of your Premier MDR.
Rapid Change™ eccentric that allows simple and fast oscillation angle changes (0.2, 0.5, 1, and 3 degrees) without calibrating. We beat the competition by over an hour!
Smart Seal™. An optional upper die assembly to eliminate the conventional elastomeric seal while maintaining a closed, pressurized cavity for improved long-term data stability and reduced need for torque calibrations.
Easy Automation. Our 3-side open enclosure makes it easy to add multiple automation options to support low to high volume production demands. Our compact, lightweight sample delivery system delivers the most reliable sample transfer system in the industry.
标准主要功能
更快. 更好的控制. 更好的分辨率.
与仪器匹配的定制电子设备。 更好的控制。更好的分辨率。其他 RPA 使用现成的可编程逻辑控制器 (PLC) 来节省资金，但无法根据仪器微调其电子设备 – 通常会超出设定点，然后花费宝贵的时间来稳定。
优质的模具冷却
高效的模具冷却使您的仪器为下一次测试做好准备。 为什么模具冷却需要等待 20 分钟，而 Premier 仪器大约需要 6 分钟。（我们的仪器足够智能，可以知道仪器何时达到正确的温度。其他仪器则不然。）
定制设计的加热控制系统.
因为它们是专门为 Premier 仪器设计的， 所以我们的加热控制系统可以更快地提高加热周期，并保持对更精确的固化时间和更高效生产的控制。
动态对称和智能对齐
更精确的测量。 得益于 Premier 的智能对齐和动态对称，不会有信号损失。准靶、平行合模、高刚度和恒定的合模力。
铸铝框架
使用更轻的铸铝框架，让您可以更聪明地工作，而不是更辛苦地工作。 Premier 框架不仅重量轻，而且非常坚固，不易变形。此外，Premier 仪器将框架合规性纳入校准中，以获得更好的数据。
便捷触摸屏
我们通过一个大而明亮的触摸屏为您提供极其直观的用户界面，让您可以快速轻松地导航到您想要的视图或您需要的信息。
收纳抽屉
好吧……这是一桩小事。但是质量保证 (QA) 和研发 (R&D) 技术人员喜欢有办法保持工作空间整洁。
