SISCO's 15-position magnetic stirrer with heating, each stirring position is equipped with an independent magnetic drive, supporting both synchronous and asynchronous operation modes to handle complex experimental needs. With a digitally controlled LED speed display, users can precisely adjust stirring speeds from 150 to 1600 rpm. Built with a corrosion-resistant, splash-proof, and heat-resistant structure, this heated magnetic stirrer ensures long-term, reliable performance in demanding conditions.
Durable and Safe Stirring Platform
- High-Temperature Resistant Stirring Plate: Our lab magnetic stirrer is crafted from high-quality aluminum alloy with a heat-resistant coating, the stirring surface offers excellent thermal conductivity and long-term structural integrity.
- Smart Overheat Protection System: An integrated temperature sensor and automatic power cut-off mechanism ensure the heating plate shuts off and issues an alert if the temperature exceeds the preset safety threshold.
- Splash-Proof Integrated Edge Design: The raised one-piece edge around the magnetic mixer's stirring area helps prevent liquid spills from reaching the control panel or internal circuitry during intense stirring or accidental overflows.
Flexible and Corrosion-Resistant Performance
- Synchronous & Independent Stirring Modes: This multi-position magnetic stirrer supports both synchronized rotation across all positions or individual asynchronous control, making it ideal for labs needing to run multiple experiments under varying conditions.
- Corrosion-Resistant Panel Surface: The magnetic agitator surface is treated with an anti-corrosive coating, resistant to strong acids and alkalis, making it well-suited for chemical, biological, and pharmaceutical environments.
- Stable and Precise Heating Control: The built-in digital controller continuously monitors and maintains the set temperature, delivering stable heating with minimal fluctuations, thus improving experiment reliability.
Applications
Magnetic stirrers are widely used in scientific and industrial settings such as university labs, chemical engineering, biopharmaceuticals, and clinical laboratories. In research and education, they enable hands-free mixing for experiments and training. In chemical and pharmaceutical fields, magnetic hotplate stirrers offer precise control of temperature and speed, ideal for synthesis, titration, and reagent preparation. In clinical labs, they help maintain consistent stirring of diagnostic samples, ensuring accurate and repeatable results. These versatile tools enhance efficiency, consistency, and reliability across a range of applications.

Q1: What is the purpose of a magnetic stirrer in titration?
A1: In titration, a magnetic stirrer ensures continuous and uniform mixing of the analyte and titrant, allowing for accurate and consistent chemical reactions. By using a lab magnetic stirrer, chemists can avoid manual shaking, reduce human error, and observe more precise color changes at the endpoint of the titration. This improves repeatability and accuracy in analytical experiments.
Q2: What may stop a magnetic stirrer from working?
A2: A magnetic stirrer may stop working due to several reasons: power supply issues, damaged motor, worn-out magnetic stir bar, misalignment between the bar and the internal magnet, or overheating of the hotplate magnetic stirrer. It’s important to ensure the stir bar is clean, properly centered, and compatible with the container size and shape to maintain optimal performance.
Q3: What are the limitations of a magnetic stirrer?
A3: While magnetic stirring systems are highly effective for small to medium volumes, they have certain limitations. They may not perform well with highly viscous solutions, large-volume samples (typically over 5L), or those containing solid particulates. Additionally, prolonged use at high temperatures may affect the durability of standard stir bars or hotplate surfaces, making them less ideal for some industrial-scale or long-duration processes.
Tips: How does a magnetic system work?
A magnetic stirring system operates by using a rotating magnetic field, generated by a motor or magnetic drive beneath the plate, to spin a magnetic stir bar placed inside the container. The interaction between the external magnetic field and the internal stir bar causes the liquid to stir. This method provides silent, efficient mixing without direct mechanical contact, making it ideal for sterile or sealed lab environments.
