<p>Computer-controlled method and apparatus for automatic melt index testing, including a housing with a base (400) carrying a heater block (450) having a bore therein for receiving a metal cartridge (550). A cartridge carousel (530) is rotatably carried on the base, and carries a plurality of such cartridges, each cartridge having a plug at a bottom end thereof with an orifice through the plug, and each cartridge having a bore therein for receiving a sample of a test substance and for receiving a piston on top of the pellets. A lift arm (870) grasps the cartridges, one at a time, and places each cartridge into the heater block, under the control of a microcomputer, by both lifting and rotating the transfer arm. The transfer arm includes a solenoid-operated grip (1000) for grasping the cartridges.</p> |
