John Morris Scientific  are pleased to offer a range of products from GÖttfert including Melt Indexers and High Pressure Capillary Rheometers.

The MI-4 is a unique Melt Indexer with an automatic weight selection. The MI-4 can carry out single weight test ISO 1133 and ASTM D1238, and procedures B and C for the "Half Height/Half Diameter" standard. Tests can be made either with a single test load or multiple test loads (several test loads per barrel filling).

The Rheograph 75 is a user-friendly High Pressure Capillary Rheometer with an enlarged shear rate range, higher test piston force and a variety of options. Windows database software allows the parameter manipulation, online monitoring as well as freely definable evaluation of results. Capillary Rheometry is a technique in which a sample undergoes extrusion through a die of defined dimensions and the shear drop across the die is recorded at set volumetric flow rates.
