Description
Simply set the sample-filled sample cup onto the carousel, set up the test conditions, and the actual testing will be done automatically. Not only the testing, but also cleaning after the test and calculation of results are performed automatically, allowing for up to 12 consecutive tests. This helps reduce variations in test results and saves the operator’s time spent on testing. We recommend this model for situations where a high frequency of daily tests and reproducibility of results are required.
*Option of 24 tests and 50 tests are also available.
In melt flow testing, air bubbles mixed into the molten resin during extrusion can cause variability in flow characteristics and affect test results. Yasuda Seiki has developed software that records MVR changes over time along with the test results, using a high-resolution rotary encoder to precisely track piston movement during testing. If air bubbles (entrapped air) are present, this appears as an anomaly in the MVR graph, allowing operators to assess the validity of test results post-test.
