Heidolph Hei-Torque 400 Overhead Laboratory Stirrer for High Viscosity Media, 100L Capacity
Product Description
The Heidolph Hei-Torque 400 is a robust overhead laboratory stirrer engineered for biotechnology and chemical research applications requiring the agitation of highly viscous solutions up to 250,000 mPas. Designed to accommodate volumes up to 100 liters (water equivalent), it supports demanding bioprocessing workflows and biomanufacturing tasks.
Key technical features include:
- Dual gear stage motor providing flexible speed ranges: Gear I (10–400 rpm) and Gear II (20–2000 rpm) for precise control in synthetic biology and molecular diagnostics protocols.
- Connectivity via RS232 and USB interfaces enabling integration with laboratory automation systems and facilitating remote process monitoring and ramp programming, essential for controlled bioprocess stirring.
- Power input of 150 W with a low-noise motor design suitable for sensitive cell culture and live-cell imaging setups.
- Quick-action chuck acceptor with a 10.5 mm diameter, optimizing compatibility with various standard stirrer shafts.
- Operation within temperatures of 5 °C to 31 °C and altitudes up to 2000 meters a.s.l., ensuring versatility in diverse laboratory environments.
- Built-in motor protection with automatic cut-out display preserves equipment integrity during continuous use in molecular cloning and biopharmaceutical production pipelines.
This overhead stirrer is widely adopted in biotechnology research, particularly in applications requiring the stirring of viscous media such as polymer synthesis, enzyme reaction mixtures, and complex cell suspensions. Its integration-friendly design and high torque capabilities make it critical in bioprocessing and synthetic biology research settings. Despite minor cosmetic wear and a missing control knob (non-impactful on functionality), the unit remains fully operational, making it a dependable choice for advanced laboratory stirring requirements.
This equipment supports essential workflows in molecular biology, biomanufacturing, and clinical diagnostic laboratories, offering precise agitation control critical for reproducible experimental results.
