RWD50 LCD Top Stirring Centrifugal Impeller 90mm Rod length 650mm

By /

This professional laboratory overhead stirrer features a 90mm centrifugal impeller and LCD display for precise control of mixing operations. The unit combines a DC brushless motor with speeds from 30 to 2200rpm and a self-locking chuck system, capable of handling up to 20L of medium to high viscosity materials.

Laboratory Mixing Solution

This overhead stirrer is engineered for mixing medium to high viscosity liquids in laboratory and industrial settings. The LCD interface provides enhanced control and safety compared to basic models. It features:

  • Self-locking chuck system for secure paddle attachment
  • Square lifting and fixing clips
  • Automatic torque adjustment based on sample viscosity
  • Overload protection with automatic shutoff
  • Built-in stirring paddle penetration port
  • Optional stirring paddles for different applications

Applications

  • Chemical synthesis
  • Pharmaceutical production
  • Physical and chemical analysis
  • Petrochemical processing
  • Cosmetics manufacturing
  • Health product development
  • Food processing
  • Biotechnology research

Paddle Options

The system supports multiple paddle types for different mixing needs:

  1. Round three-hole fan type (for soft stirring)
  2. Dissolving paddle (for high viscosity liquids)
  3. Three-blade paddle (for axial flow mixing)
  4. Centrifugal paddle (for narrow containers)
  5. Four-blade paddle (for medium/low viscosity)
  6. Screw type paddle (for high viscosity)
  7. Round six-hole fan type (for gentle mixing)
  8. One-word paddle (for medium/low viscosity)
  9. Round anchor paddle (prevents wall deposits)
  10. Square anchor paddle (for polymer reactions)
  11. Square hole fan type (for medium/low speed mixing)
