A magnetic stirrer is a lab device that mixes low-viscosity liquids or solid-liquid mixtures with or without heating. The SISCO multi-position magnetic stirrer allows multiple samples to be stirred simultaneously, boosting lab efficiency. It operates using a rotating magnetic field that drives the magnetic stir bar inside the container, ensuring smooth and uniform mixing. It is widely used in research labs, education, and industrial settings.
Safety Protection and Precise Temperature Control
- IP42 Protection Rating: This multi-position magnetic stirrer features a splash-resistant frame to effectively prevent liquids from entering the internal components, ensuring safe operation even in humid lab environments.
- Digital Temperature Controller: The heating plate is equipped with a high-precision digital temperature controller, paired with an LED display and rotary knob for easy temperature setting and real-time monitoring. The data is clear and highly accurate.
- Heat-Resistant Top Plate: The surface of the magnetic hotplate stirrer is made of either microcrystalline ceramic or ceramic-coated aluminum, offering excellent thermal stability. Even under high temperatures, the plate remains flat and durable, ensuring reliable heating performance and long service life.
Strong Magnetic Fixation and Intelligent Safety Features
- High-Performance Magnetic System: This multi-position magnetic stirrer with heating uses powerful magnets to keep the stir bar firmly in place, enhancing stability and mixing efficiency during operation.
- Overheat Protection: Built-in intelligent overheating protection automatically shuts off the power if the temperature exceeds the set limit, effectively preventing equipment damage and laboratory accidents.
- Hot Surface Warning Indicator: When the surface temperature exceeds 50°C, the hot surface warning light will illuminate to alert users, enhancing operational safety.
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 are the advantages of a multi-position magnetic stirrer compared to a single-position model?
A1: A multi-position magnetic stirrer—such as a 3-position magnetic stirrer—offers significant advantages in laboratory efficiency by allowing simultaneous stirring of multiple samples. This is particularly beneficial for parallel experiments or comparative studies under different conditions. Each stirring position typically features independently adjustable speed and heating controls, ensuring precise parameter matching for diverse experimental needs and minimizing batch-to-batch variability.
Q2: Can a multi-position magnetic stirrer operate at different stirring speeds simultaneously?
A2: Yes, most high-quality multi-position magnetic stirrers allow independent speed control for each stirring point. This enables tailored stirring speeds to suit the specific requirements of each sample, ensuring optimal mixing performance and improving the accuracy and repeatability of your laboratory experiments.
Q3: What could cause uneven stirring at one of the positions on a multi-position magnetic stirrer?
A3: Uneven stirring on a multi-position magnetic stirrer can result from a variety of factors, such as using an incompatible stir bar (e.g., incorrect size or shape), setting an inappropriate stirring speed, or dealing with liquids of high viscosity or those containing undissolved particles. Additionally, an uneven container base or improper placement may disrupt the magnetic coupling, while insufficient magnetic strength or internal mechanical issues within the stirrer can also lead to instability. Ensuring the use of compatible labware, proper setup, and routine maintenance helps maintain consistent and efficient stirring performance.
Tips: How to properly clean the heating plate of a multi-position magnetic stirrer?
To maintain your magnetic stirrer in top condition, follow these cleaning guidelines:
- Power off the unit and allow the heating plate to cool completely.
- Wipe the surface with a damp cloth—avoid abrasive or corrosive cleaners.
- For stubborn stains, use a mild detergent and gently clean, then dry with a soft cloth.
- Periodically inspect the ceramic-coated or glass-ceramic surface for cracks. If damaged, replace or service promptly to avoid safety risks.
