Small differences in temperature, loading, timing, or operator technique can shift melt flow results even when the polymer itself has not changed. Qualitest’s August newsletter examines the QualiFi™ Melt Flow Indexer lineup for MFR and MVR testing across manual, semi-automatic, and automatic workflows. With test temperatures from 50 to 450°C, configurable loading and cleaning functions, and support for ISO 1133 and ASTM D1238, these systems help polymer laboratories improve repeatability, manage throughput, and reduce operator-dependent variation.
