Overhead Stirrers (Digital)

Ideal for digital controlled high performance stirring task.

Intelligent speed controller enables reproducible results under varying viscosity condition.

Performance & Convenience

• Years of vibration-free and silent operation.

   - Equipped with a maintenance-free BLDC motor to generate smooth, quiet, and yet powerful stirring.

• Powerful torque capable of handling high viscosity tasks.

• Maintenance of constant motor speed by PID feedback control system even under conditions of changing viscosity.

• Best effort function intelligently manages its stirring speed to keep stirring even workload is out of its capacity.

• Prevention of accidental spills or splashes thanks to microprocessor controlled smooth start and stop functions.

• Well illuminated digital display panel with sensitive touch buttons.

   - Set/present rpm, power ratio (%) and run time are visible together on one screen.

• Stirring directions are selectable depending on each impeller’s shape.

• Built-in USB port for external control and data collection.

   - Lab Companion software and USB cable are provided.

• Compact and slim head design for diverse flexibility in configuring other test equipment and accessories. (optional)

Safety

• Sturdy aluminum main body efficiently absorbing and emitting the heat generated by the motor.

• Safety features against overload and overheating for continuous operation.

• Keypad lock function prevents accidental changes.

Impellers

Propeller impellers

•  Standard grade stainless steel with Teflon shaft produces an-axial flow stir between the bot-tom and top levels of a sample with local shearing force. Used at medium or high speeds for mixing normal range level viscosity samples.

Turbine impellers

• A radial flowing stir from the top and bottom levels of a sample with a powerful, high shearing turbulent force. Used ideally for the gassing of liquids and mixing medium to high range level viscosity samples.

Half-moon impellers / Centrifugal impellers

• Tiltable moon-shaped and blade shaft produces a normal axial flow percentage mixing of samples. Used with round bo-ttom shaped containers, medium mixing speed, and samples ranging from low to medium visco-sity levels.

Anchor impellers / Paddle impellers

• An anchored shaft that produces a strong tangential flow with a high shearing percentage force on samples with medium to high viscosity level with speed setting in the low to medium range.
