    • A stationary plate assembly for a rheometer that selectively provides steady state and dynamic testing of melt viscoelastic characteristics of a material sample. The stationary plate assembly has a stationary sample plate magnetically coupled to its supporting member. Therefore, after the steady state testing is complete, the movable plate, material sample and stationary plate may be moved vertically away from the stationary plate supporting member. Therefore, any spurious, erratic rotations of the movable plate when the rheometer is switched form the steady state test mode to the dynamic test mode will not cause a further working of the material sample.
    • 用于流变仪的固定板组件,其选择性地提供材料样品的熔体粘弹性特性的稳态和动态测试。 固定板组件具有磁性耦合到其支撑构件的固定样品板。 因此,在稳态测试完成之后,可移动板,材料样品和固定板可以垂直移动离开固定板支撑构件。 因此,当流变仪切换形成稳态测试模式到动态测试模式时,可移动板的任何虚假的,不稳定的旋转将不会导致材料样品的进一步的工作。
