Overview

The Side Stream Rheometer is based on the first melt return on-line Capillary rheometer developed by Goettfert many years ago. The new SSR uses the same annular melt transfer line as the old (the advantage is that only one tap hole is needed, making installation simple) and no waste stream is generated because the tested material is returned.
Features

• The SSR's annular melt transfer line adapter readily attaches to existing standard M18 and × 1.5 ports, often used for pressure, temperature and other transducers.
• The convenient installation means money savings in the planning, design and execution stages, because no flanges need to be fitted, holes drilled, or modification made to extruders.
• The compact design makes it possible to mount the instrument vertically as well as horizontally.
• The SSR is available in single or dual (two dies in series) die design. A dual point measurement provides enough information to not only measure viscosity (or indicate melt index), but also simultaneously the flow exponent, which is an important indicator of change in the molecular weight distribution.
• Our new SSR benefits from many years of experience with our Windows® software ROSWin designed for use with our other on-line rheometer systems RTR-RTS and MBR. With this stable platform it is possible to run melt flows in the range of 0.1-1700 g/10 min without changing dies.
