Key Benefits at a Glance

·       Superior Torque for High-Viscosity Media: Confidently mix even the most demanding formulations with viscosities up to 250,000 mPas.

·       Exceptional Process Control & Visibility: Monitor and control your process with a clear 2.4-inch digital display, including a real-time torque trend indicator.

·       Quiet, Safe, and User-Focused Operation: Advanced motor technology ensures minimal noise, while safety touch controls prevent accidental startup.

·       Unmatched Versatility and Compatibility: Ideal for fume hoods and reactor systems, featuring a universal 10.5 mm quick-chuck that accepts a wide range of stirring tools.

Solving Critical Laboratory Pain Points

Laboratory professionals face consistent challenges in mixing and stirring. The Hei-TORQUE Expert 400 is engineered to provide direct solutions:

·       Pain Point: Inconsistent mixing or motor stall when handling high-viscosity samples, gels, or dense suspensions.

o   Our Solution: A robust 400 Ncm of maximum torque and a dedicated low-speed gear (10-400 rpm) ensure powerful, consistent stirring without stalling, guaranteeing homogeneous results every time.

·       Pain Point: Lack of process insight and data, leading to irreproducible results.

o   Our Solution: The integrated torque trend display allows you to visually monitor the mixing resistance, providing valuable data on viscosity changes and ensuring process consistency and repeatability.

·       Pain Point: Equipment that is difficult to operate, clean, or integrate into specific setups like fume hoods or reactors.

o   Our Solution: With an intuitive interface, a compact design, a secure quick-chuck system, and a standard telescopic stand for easy height adjustment, the Hei-TORQUE Expert 400 simplifies setup, operation, and integration.
