Digital Overhead Stirrer 2200 RPM for up to 20 Liters - LGI-OS-20

The Digital Overhead Stirrer 2200 RPM for up to 20 Liters – LGI-OS-20 is designed for mixing low to medium viscosity liquids in laboratory, analytical and quality control procedures. It operates with a brushless DC motor and digital speed control, maintaining constant rotation even under load variation, ensuring stability during long-term and repetitive processes. The system allows precise speed adjustment and real-time torque monitoring, making it suitable for solution preparation, solid dispersion, chemical synthesis and physico-chemical analyses. The equipment is not suitable for volumes above 20 liters or for fluids exceeding the specified viscosity range.

FAQ

• Q: Can the stirrer operate continuously for long periods?
  A: Yes. The equipment is designed for continuous operation when used within the specified load and viscosity limits.

• Q: Is it suitable for high viscosity liquids?
  A: It is suitable for liquids up to 10,000 mPa·s. Higher viscosities may affect performance and safety.

• Q: Can different stirring shafts be used?
  A: Yes. The chuck supports shafts from 0.5 to 10 mm, allowing the use of different compatible impellers.

• Q: Does the equipment maintain constant speed under load variation?
  A: Yes. The microprocessor-controlled system automatically adjusts motor power to maintain constant speed.
