Stirring Device

A heating magnetic stirrer is a widely used sample preparation device in laboratories. It mainly consists of a motor, permanent magnets, and a control circuit. By utilizing magnetic field and vortex principles, the instrument generates a rotating magnetic field near the magnetic base during operation. This magnetic field drives the stir bar to rotate in a circular motion, creating a vortex inside the container and achieving effective mixing.

The base of the heating magnetic stirrer also features a heating function, allowing the solution to be heated to the desired temperature while being continuously stirred.

Frequently Asked Questions (FAQ)

1. What is a Heating Magnetic Stirrer?

A heating magnetic stirrer is a laboratory device used for mixing and heating liquids at the same time. It uses a rotating magnetic field to drive a magnetic stir bar inside the container, creating continuous and uniform mixing.

2. How does a Heating Magnetic Stirrer work?

The instrument generates a rotating magnetic field through the magnetic drive system. This magnetic field drives the stir bar inside the container to rotate, creating a vortex and mixing the liquid. At the same time, the heating plate can heat the sample to the required temperature.

Q3: What types of liquids can be mixed with a magnetic stirrer?

Magnetic stirrers can be used for water-based solutions, chemical reagents, solvents, buffer solutions, biological samples, and other low- to medium-viscosity liquids.

Q4: What containers are suitable for this magnetic stirrer?

Use non‑magnetic vessels: glass beakers, glass flasks, non‑magnetic metal and non‑metal containers. Iron‑based magnetic containers cannot be used, which will block magnetic transmission.

Q5: What is the maximum stirring capacity?

The maximum stirring capacity depends on the model. Different magnetic stirrers are available for small laboratory samples as well as larger-volume applications. Please select the appropriate model according to the liquid volume and viscosity.
