The magnetic stirrer will generate rotational force to drive the substance to rotate quickly. In this way, the substance is completely mixed, and the substance can be concentrated by heating. Multiple uses: Laboratory bar can be applied with various types of magnetic stirrers or heating stirrers. Stir plate magnet is widely applied in scientific research, universities, laboratories in the industrial and agricultural sectors, and is often applied to stir mixed substances. Specifications: Color: as pictures shown Material: PTFE and quality magnetic steel Size: 35 mm/ 1.38 inch Note: Please allow a little error on the size due to manual measurement.
