The modular GOETTFERT mi-2 series melt flow indexer allows users to upgrade from a manual operated entry-level unit to a semi-automatic machine.

  • ISO 1133
  • ASTM D1238
  • ASTM D3364

The mi-2 Melt Flow 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 Flow Index machines offer additional benefits, besides from just running according to ISO and ASTM. One such example would be obtaining elongational information. 


The melt flow 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 Flow 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 Flow 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: 

  • Die Swell measurement 
  • integrated determination of the melt density, via interfaced laboratoy scale. 
Optional units
  • fixation unit to hold the base weight before the test range until the melt time is over 
  • ISO 1133 method C set (half height, half length) 
  • Die swell measurement 
  • melt cutting unit 
  • balances 
  • Die plug 
  • nitrogen purge 
  • feeding tool for low viscous materials 
  • battery powered cleaning device 
  • control thermometer
