Heidolph Hei-Torque 400 High-Viscosity Overhead Stirrer with 100L Capacity and 2000 RPM Speed
Product Description
The Heidolph Hei-Torque 400 is a precision-engineered overhead stirrer designed for demanding laboratory mixing and bioprocessing applications requiring powerful torque and volume capacity. Key features and specifications include:
- Viscosity Handling: Capable of stirring media up to 250,000 mPas, ideal for high-viscosity samples encountered in molecular diagnostics and synthetic biology workflows.
- Volume Capacity: Supports batch volumes up to 100 liters (H2O equivalent), suitable for large-scale biomanufacturing and bioprocessing tasks.
- Speed Range: Dual-gear motor enables rotational speeds from 10 to 400 RPM (Gear I) and 20 to 2000 RPM (Gear II), allowing precise control for various mixing intensities essential in biotechnology research and cell imaging preparations.
- Motor and Drive: Equipped with an efficient EC motor delivering up to 400 Ncm torque, ensuring consistent stirring of highly viscous media for continuous operation.
- Connectivity: Integrated RS232 and USB interfaces facilitate seamless integration with laboratory automation systems and data acquisition software, enhancing workflow automation in clinical diagnostics and molecular biology labs.
- Operation: Features touch-sensitive controls with programmable ramps for time-dependent stirring profiles, minimizing noise and optimizing process reproducibility.
- Mechanical Design: Includes a quick-action chuck compatible with a variety of stirring tools, supporting versatile applications from bioprocessing to chemical emulsification.
- Durability and Safety: IP54 rated protection class for reliable performance in humid lab environments. Motor temperature monitoring with KTY sensors extends equipment lifespan.
- Environmental Conditions: Operates efficiently within 5 °C – 31 °C at 80% relative humidity and 32 °C – 40 °C at 50% relative humidity, suitable for standard laboratory and biomanufacturing environments. Installation altitude up to 2,000 meters above sea level.
The Heidolph Hei-Torque 400 is widely adopted in synthetic biology research and bioprocessing labs, supporting critical mixing tasks in biopharmaceutical production pipelines and molecular cloning workflows. Its powerful performance and programmable features make it essential for research professionals requiring robust and adaptable stirring solutions for live-cell imaging, fluorescence analysis, and biotechnology applications.
Note: This unit is preowned with minor wear; the control knob is missing but functionality remains unaffected due to touch-sensitive operation. The stand is not included.
This overhead stirrer is a technically advanced solution for laboratories prioritizing precision torque control and scalability in mixing highly viscous fluids.
