Designed for efficiency, SmartMelt ensures quick training, fast measurements, and dependable outcomes.
Key features
Comprehensive polymer melt rheology beyond one-point measurements
In contrast to one-point measurements such as the Melt Flow Index (MFI), the SmartMelt series determines the full shear-rheological picture, including flow curve, oscillation, creep, relaxation tests, and more. The SmartMelt polymer melt rheometers are designed with modularity in mind, and measuring systems and other accessories can be exchanged to fit all of your needs. The series also complies with ASTM D4440 and ISO 6721.
Unparalleled temperature precision at an affordable price
The renowned Anton Paar ETD is the most cost-effective and high-performing electrical temperature oven for a polymer melt rheometer on the market. Covering a range of -150 °C to +400 °C, it offers direct temperature measurement at the sample, ensuring a temperature gradient of almost zero within the sample. The temperature calibration kit for automatic calibration ensures 100 % reliable results.
Fast training, reliable results
A series of tools optimizes time-to-measurement and delivers reliable polymer melt rheology results, while reducing training time for operators:
- Toolmaster: Automatic recognition of measuring geometry and cell
- QuickConnect: One-handed coupling of the measuring geometry in seconds
- RheoCompass templates: Pre-prepared measuring workflows
- Sample preparation and cleaning tools
- Touchscreen (only for SmartMelt 303): Full sample preparation directly at the instrument
Save energy, reduce noise, and maximize precision
The resource-friendly SmartMelt series ensures cost savings and environmental sustainability by using minimal compressed gas and energy, all while maintaining quiet operation for a better working environment. The option to use inert gas prevents sample degradation for more reliable results for your critical applications. This combination of efficiency, precision, and sample protection makes SmartMelt the ideal choice for polymer melt rheology.
