MP1200 Melt Indexer

The MP1200 features the latest in melt flow measurement technology and allows operators to quickly and easily set up and perform melt flow tests: according to ASTM D1238, ISO 1133-1 & 2, and other international and industrial specifications.

The MP1200 is available in two distinct versions, a manual version (model MP1200), and a motorized version (model MP1200M). The manual MP1200 comes with everything you need (except weights and laboratory balance) to perform an ASTM D1238 Procedure A (manual cut) gravimetric melt flow rate (MFR). Test loads are applied manually on MFI testers. This equipment also known as extrusion plastometer.

The MP1200 can be upgraded with optional features, including ISO 1133 tools and an encoder-based programmable piston displacement transducer (or PPDT for short), for testing according to Procedures B & C (ASTM D1238) or for volume measurement tests (melt volume rate or MVR) and melt density calculations.


Also available as options are Tinius Olsen’s manual and automatic specimen cutting tool attachments, which can be used with some materials to reduce the human involvement with the machine during the test and increase accuracy and repeatability of test results. The MP1200M is equipped with a motorized weight lifting and lowering device (WLD) that further automates the testing procedure. The WLD safely and automatically applies test weights to the piston at a user selected time interval during the test. It is also available with the PPDT and cutter options, as well as the Flow Rate Ratio (FRR) attachment for ASTM D1238 Procedure D for polyethylene and the Purge and Purge/Clean options.
