The mi-2 Melt Index series can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures A, B and C. In addition it runs tests according to ASTM D 3364. The mi-2 easily performs melt-flow-rate (MFR), as well as melt-volume-rate (MVR) measurements. Due to the modular design of this system, it is possible to automate the measurement process step by step. The extrusion plastometer can be used either as a stand-alone instrument, or it can be run with a computer software for statistical analysis and data management. Depending on options, GOETTFERT Melt Index machines offer additional benefits, besides from just running according to ISO and ASTM. One such example would be obtaining elongational information.
The melt indexer mi 2.1 shows fit for quality control (QC) where only one weight is used. In addition, it is useful when only a few measurements are made.
The melt-indexer mi2.2 is equipped with an automatic weight lifting system. This makes it much easier for the operator to handle weights of 5kg and more. As a time saving option, it also allows the automated start of the measurement right after the melt time is over. Weights can also be lifted at the end of the test, to allow an easy cleaning process.
The melt-indexer mi2.3 has a full weight handling system, whose cartridge holds up to 8 weights. There is no need anymore to lift or move weights manually.
For the mi2 series additional Add-ons are available, which are extending the functionality of the instrument:
