Thermo Fisher Scientific Launches New Suite of Micro-Conical Twin-Screw Compounders

MUNICH (March 23, 2010) – Thermo Fisher Scientific Inc., the world leader in serving science, today launched the Thermo Scientific HAAKE MiniCTW, the latest model in a suite of micro-conical twin-screw compounders. These machines feature several models that serve a variety of markets, including polymer, bioscience, nanotechnology and pharmaceutical. The company will introduce and showcase the new HAAKE MiniCTW at Thermo Scientific booth 101 in Hall B1 during Analytica 2010, being held March 23 - 26, in Munich, Germany.

All models use as little as 5 grams or 7 milliliters (ml) of material for compounding, which is especially beneficial for industries that compound expensive or small-scale materials such as nano-composites, bio-polymers or pharmaceuticals. By using the optional force feeder, customers can continuously extrude very small material volumes. The instrument is based on proven, conical twin-screw technology with co-rotating and counter-rotating screws, and works as a standalone unit with data export. The residence time is well-defined due to the channel and a bypass valve.
The Thermo Scientific HAAKE MiniCTW is ideal for the precisely controlled reactive extrusion of high-viscous melts. By running the instrument in circulation mode, the required reaction time for the reactive mixture can be easily controlled. At the end of the test, the bypass valve can be opened and the sample extruded as a strand. By measuring the torque of the drive motor, the reaction process can be monitored effectively.
Features and benefits of the new suite of micro-conical twin-screw compounders include:

• Requires only 7 ml of material for compounding
• Removable top barrel for easy and quick cleaning
• New software for user-friendly process monitoring
• Various models serving a breadth of applications (from polymers to pharmaceuticals)
