Digital Overhead Stirrer 2200 RPM for up to 40 Liters – LGI-OS-40

The Digital Overhead Stirrer 2200 RPM for up to 40 Liters – LGI-OS-40 is designed for mixing medium to high viscosity liquids in laboratory, industrial and quality control processes. It operates with a brushless DC motor and microprocessor-based digital control, maintaining stable rotation even under significant load and viscosity variations. The system allows precise speed adjustment and continuous torque monitoring, providing real-time information on changes in fluid behavior during operation. It is suitable for solution preparation, solid dispersion, chemical synthesis and physico-chemical analyses, and is not intended for volumes above 40 liters or viscosities exceeding the specified limit.
