Abstract
Described is a device for removal of excess material from a test sample. The test sample may be used in an instrument for measurement of rheological and mechanical properties sample properties. The device includes a test geometry and a trimming ring. The test geometry includes a lower geometry and upper geometry each having a circular outer edge and being centered on an axis of rotation. The trimming ring has a sidewall, a ring axis coincident with the axis of rotation and at least one cutting edge disposed along at least a portion of a circumference of the trimming ring at a diameter that is at least as great as a diameter of one or both the lower geometry and the upper geometry. The device further includes an actuator coupled to the trimming ring and configured to translate the trimming ring in a direction parallel to the axis of rotation.
