Melt Flow Tester
The Instron® CEAST MF50 multi-weight Melt Flow Tester performs melt flow rate (melt index) tests according to MFR and MVR methods that fully comply with ASTM D1238 procedures A, B, C, D, and ISO 1133 A and B, for single weight and multiple weight tests .
Multi-weight tests can include up to 5 masses in increasing, decreasing or free sequence, with fully customizable preheating and measurement steps. All masses are pre-installed and managed by the machine without operator intervention, eliminating all safety concerns. A high-resolution direct-contact encoder measures piston displacement. The temperature profile in the barrel is extremely stable and accurate. Additional advanced features include a large touch-screen display for full test programming, management and diagnostic functions, with an embedded PC based on Windows CE, able to store test methods and test results. Easy data export through USB and Ethernet ports. Compacting and purging functions can be supported by the unique load cell feature. Automatic melt cutting and barell cleaning accessories are also available.
