Digital Heated Magnetic Stirrer for Laboratory, 5L

Details

Q1: What is the advantage of a magnetic stirrer?
A1: A magnetic stirrer uses a magnetic field to drive a stir bar, enabling contact-free mixing that eliminates seal leakage issues common in traditional mechanical stirrers. With adjustable stirring speeds and smooth operation, it minimizes splashing and air bubble formation. When equipped with a digital temperature control function, the heated magnetic stirrer maintains precise heating conditions, improving experiment reproducibility. Its compact design and ease of use make it ideal for sterile and cleanroom environments. A laboratory magnetic stirrer is an essential laboratory mixing tool for accurate temperature control and efficient liquid handling in chemical, biological, and pharmaceutical labs.

Q2: What is the difference between a magnetic stirrer and a hot plate?
A2: A magnetic stirrer is designed to mix liquids using a rotating magnetic field and typically includes variable speed and digital temperature control, making it ideal for laboratory applications requiring uniform mixing and precise heating. A hot plate, on the other hand, only provides surface heating without stirring capability and is used for simple heating or melting tasks. For advanced laboratory experiments, a magnetic hotplate stirrer combines both functions, offering both controlled mixing and heating in one device, perfect for chemistry, biology, and material science applications.

Q3: What precautions should be taken when using a magnetic stirrer with a hot plate?
A3: Ensure that the container is made of heat-resistant material and has a flat bottom to avoid uneven heating. Regularly check the synchronization between the stir bar and magnetic field to prevent slippage or disengagement. Set a maximum temperature limit and use the overheat protection feature to avoid boiling or dry burning. Wear heat-resistant gloves during operation, keep flammable materials away, and ensure proper ventilation. After use, turn off the power and allow the unit to cool before cleaning to avoid burns or equipment damage.

Tips: What to do if the magnetic stirrer heats unevenly or the stir bar doesn’t spin?

• Check if the container is properly centered and in full contact with the hotplate.
• Ensure the bottom of the container is flat and undamaged—replace if necessary.
• Inspect the magnetic stir bar for demagnetization (common after prolonged high-temperature use); replace if needed.
• Keep the distance between the hotplate surface and the stir bar within 5mm to maintain magnetic strength.
• Evaluate the viscosity of the liquid and the size of the stir bar—adjust the stirring speed or switch to a more suitable stir bar if needed.
