Introduction
Overhead Stirrer enables a 70-liter mixing capacity ideal for large-volume laboratory processes. It operates from 50 to 1100 rpm, allowing effective control of low-speed stirring tasks. Designed with a brushless DC motor and silicone cover that shields the chuck from corrosive vapour. It starts and runs smoothly to prevent sample splatter or overflow during extended use. Suitable for continuous, high-load mixing in chemical, pharmaceutical, and industrial lab environments.
This magnetic stirrers is designed to meet the rigorous requirements of modern laboratory operations, ensuring high precision, reliability, and ease of use for various experimental applications.Applications
Our Overhead Stirrer is designed for continuous mixing of dense suspensions, emulsions, and high-viscosity samples in industrial and research labs.

FAQs
1. What types of substances can the Overhead Stirrer handle effectively?
The Overhead Stirrer is ideal for dense, viscous materials such as slurries, pastes, or polymer solutions. It’s often used in formulations where consistent agitation over a long period is critical. The torque capacity enables uniform blending of difficult-to-mix substances. Users in industrial or pilot-scale labs rely on its strength for process consistency.
2. Is the Overhead Stirrer suitable for continuous use in production environments?
Overhead Stirrer is designed for long-duration mixing and supports extended operation with high-viscosity samples. The cooling system and brushless motor allow uninterrupted use without overheating. It is suitable for batch production or continuous process applications in research, chemical, or biotech settings. For best performance, verify shaft balance before extended use.
3. How does the Overhead Stirrer support time-controlled mixing protocols?
Overhead Stirrer includes a timer function for precise time-based stirring tasks. Users can set durations up to several hours, making it ideal for protocols requiring consistent agitation. This feature is especially helpful in formulations that must be stirred for exact periods. It reduces manual intervention and improves reproducibility.
4. Can the Overhead Stirrer be cleaned easily between different formulations?
The Overhead Stirrer features an enclosed structure that simplifies cleaning. The shaft can be removed and cleaned separately. The body is resistant to splashes and can be wiped with standard lab-grade disinfectants. Avoid spraying directly near the control interface and always disconnect power before cleaning.
5. How can the Overhead Stirrer contribute to process development?
Overhead Stirrer is often used in pilot labs or early-stage product development. Its torque and speed controls support optimization of new formulations. Users can replicate stirring conditions required for scale-up studies. This helps bridge the gap between benchtop research and full production.
