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.
Prevention of accidental spills or splashes thanks to microprocessor controlled smooth start and stop functions.
Designed for simple and quick operation.
Well illuminated digital display panel with sensitive touch buttons.
- Set/present rpm are visible together on one screen.
Compact and slim head design for diverse flexibility in configuring other test equipment and accessories. (optional)

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.
