The BKMAMLAB overhead stirrer (also referred to as a mechanical stirrer, laboratory overhead stirrer, or digital overhead stirrer) is a high-performance lab instrument designed for liquid-liquid mixing, solid-liquid mixing, and high-viscosity sample stirring experiments. With a maximum mixing capacity of 40 L and a speed range of 30-2200 rpm, this overhead lab mixer delivers precise and reliable performance for diverse applications.
Equipped with a brushless DC motor and dynamic torque adjustment, the overhead mixer automatically adjusts torque based on sample viscosity to maintain constant speed. The smooth start technology prevents sample splashing, while the enclosed anti-corrosion housing and multiple safety protections ensure safe operation. With a backlit LCD screen and 5-set speed memory, this lab agitator simplifies experimental procedures and improves workflow efficiency.

The overhead stirrer features precise speed control with an accuracy of ±3 rpm, ensuring consistent and reproducible mixing results. The real-time display shows both set and actual values, allowing you to monitor and adjust the speed with confidence. This level of precision makes it an ideal laboratory mechanical stirrer for sensitive experiments.
This digital overhead stirrer automatically adjusts torque according to sample viscosity, ensuring the motor maintains a constant speed even as the viscosity of your sample changes. This intelligent feature delivers stable performance across a wide range of applications, from low-viscosity liquids to high viscosity overhead stirrer tasks up to 60,000 mPa·s.
The overhead lab mixer features smooth start technology that gradually increases speed, effectively preventing sample splashing during startup. This is particularly important when working with precious or hazardous samples, ensuring both sample integrity and user safety.
This lab agitator is equipped with comprehensive safety features:
Enclosed anti-corrosion housing protects internal components.
Automatic power-off and alarm upon overload, short circuit, or abnormal speed.
Self-locking universal chuck ensures the stirring paddle remains securely attached.
The overhead mechanical stirrer features a backlit LCD screen that displays speed and time parameters clearly. The 5-set speed memory function allows you to save and recall frequently used settings, simplifying experimental procedures and reducing setup time.
Equipped with a brushless DC motor, this electric overhead stirrer delivers high efficiency, long service life, and maintenance-free operation. The motor provides consistent power output, ensuring reliable performance for demanding mixing tasks.
Our Need | Recommended Model |
|---|---|
Precision lab applications, small-scale production | Overhead Stirrer – 40L capacity, 30-2200 rpm, 200W, 60,000 mPa·s. |
Medium-to-large industrial production lines | Cantilever Stirrer – 60L capacity, 50-3000 rpm, 200W, 30,000 mPa·s. |

Place the overhead stirrer on a stable, flat, and level work surface.
Install the stirring paddle into the self-locking universal chuck and tighten securely.
Position the stand so that the stirring paddle is centered in your mixing container.
Use the backlit LCD screen to set the desired speed (30-2200 rpm).
Set the timer (1-9999 min) if required.
Use the 5-set speed memory function to recall frequently used settings.
Press the start button. The smooth start technology will gradually increase speed to prevent splashing.
The overhead stirrer will automatically adjust torque to maintain the set speed, even as sample viscosity changes.
Monitor the display to ensure the actual speed matches the set value.
When mixing is complete, press stop and allow the stirring paddle to come to a complete halt.
Remove the paddle and clean it thoroughly.
Wipe the main unit with a damp cloth. Do not immerse the overhead mixer lab in liquid.
Precautions:
Do not plug or unplug the power cord with wet hands.
Do not operate the overhead stirrer without a properly installed stirring paddle.
If the overload alarm sounds, stop immediately and check for obstructions or excessive load.
Do not use the high torque overhead stirrer for applications exceeding its maximum capacity (40L or 60,000 mPa·s).
