Melt Flow Testers


Instron®’s CEAST Melt Flow Testers are specifically designed for easy and accurate measuring of the Melt Flow Rate (MFR) and the Melt Volume Rate (MVR). CEAST Melt Flow Testers range from systems that perform a simple manual test procedure to semi-automated testing systems performing multiple weight tests. Our testers meet ASTM and ISO standards.

CEAST MF20 is a versatile Melt Flow Tester for single-weight tests, compliant with the latest international standard requirements for temperature accuracy and stability. It is an ergonomic and compact system designed for easy and safe testing and maintenance.
