Key Features & Safety

  • High-Spec Controllers: Digital models utilize feedback controllers for exact RPM management, easily adjusted via jog dials.
  • Sample Protection: Includes a Slow Start/Stop function to prevent sample splashing during initial operation.
  • Durability: Chucks are chromium-coated to ensure they remain rust-free even during long-term use.
  • Versatility: Features a penetrated shaft for easy impeller height adjustment and reduced shaking.
  • Integrated Safety: All models include motor overheating prevention devices; digital models add overload protection.
  • Advanced Monitoring (High-Performance): The OSH-series provides real-time torque indication and can measure or target specific viscosities.

 

Specialized Stirring Solutions

  • Jar Testers: Available in 4-place (portable) or 6-place models for water agglutination experiments. These include specialized illumination for easy sample observation.
  • Magnetic Stirring: Integrated options are available in our Hotplate Stirrer (up to 1500 rpm) and Stirring Heating Mantle lines for combined heating and mixing.
