Hotplate Magnetic Stirrer ADHMS-501

1. What is a Hot Plate Magnetic Stirrer?

A Hot Plate Magnetic Stirrer is a lab device that heats and stirs liquids at the same time. It uses a rotating magnetic field to spin a stir bar inside the container. This ensures uniform heating and consistent mixing during experiments. Its compact design and precise control make it essential for chemistry, biology, and research applications.

2. Which types of liquids are suitable for use with a Hot Plate Magnetic Stirrer?

Hot Plate Magnetic Stirrers are ideal for water, aqueous solutions, buffers, and most low-viscosity organic solvents. However, always check that your liquid is chemically compatible with the plate surface and the PTFE-coated stir bar. Avoid using highly flammable, corrosive, or viscous liquids unless your device is specifically rated for such applications, as these can pose safety or performance issues.

3. What is the typical stirring speed range of a Hot Plate Magnetic Stirrer?

Hot Plate Magnetic Stirrers offer a speed range between 100 to 1500 revolutions per minute (RPM), though some advanced models can go higher. Lower RPMs are suitable for gentle mixing of sensitive solutions, while higher RPMs are used for rapid agitation or dissolving solids. It's best to start at a low speed and increase gradually to prevent splashing, stir bar decoupling, or container instability.

4. How long does it take to heat liquids in a Hot Plate Magnetic Stirrer?

In Hot Plate Magnetic Stirrer, the heating time varies depending on the liquid's volume, initial temperature, and the wattage or efficiency of the hot plate. Small volumes may heat up in just a few minutes, while larger ones (over 1 liter) may take 15–30 minutes or more. Stirring during heating improves thermal distribution and helps avoid hotspots or uneven temperature gradients.

5. Can I use plastic containers on a Hot Plate Magnetic Stirrer?

Plastic containers are generally not recommended for use on Hot Plate Magnetic Stirrers, especially when heating is involved. Most plastics have relatively low melting points. It's always best to use borosilicate glassware like beakers, flasks, or other lab-grade containers that can withstand both the heat and the magnetic forces.

6. What safety features are included with the Hotplate Magnetic Stirrer?

Safety features of Hotplate Magnetic Stirrer typically include overheat protection, temperature limit controls, non-slip feet to prevent the unit from shifting, and a thermal shut-off to protect against overheating. Always ensure to operate the unit according to the instructions and use appropriate safety gear, such as heat-resistant gloves and eye protection.

7. What are the advantages of using a Hotplate Magnetic Stirrer?

The advantages of using a Hotplate Magnetic Stirrer include its ability to heat and stir liquids simultaneously, offering precise temperature control and uniform mixing. It reduces the risk of contamination due to its non-contact stirring mechanism, making it ideal for sensitive applications. The device is compact, energy-efficient, and low-maintenance, with easy-to-use controls and built-in safety features such as overheat protection.

8. Can a Hotplate Magnetic Stirrer be used for precise temperature control?

Yes, our Hotplate Magnetic Stirrers come with built-in temperature control features, including temperature probes for accurate measurement and control of the heating element. This allows for precise temperature regulation, making the device suitable for experiments that require specific thermal conditions, such as enzyme reactions or solvent evaporation. Our Advanced models also feature digital displays and programmable settings for enhanced accuracy and repeatability.
