What is the most indispensable part of the magnetic stirrer?

Correct! Magnetic stirrer. Magnetic stirrers are usually made of polytetrafluoroethylene (PTFE, F4). Why is it made of Teflon? Because of its high temperature resistance: use temperature -200 ~ +250°C; low temperature resistance: -196 ° C can maintain 5%; corrosion resistance: strong acid, alkali, aqua regia and various organic solvents; resistance to insulation: dielectric properties and temperature , frequency independent; high lubrication: the lowest friction coefficient of solid materials; no adhesion: no adhesion to any substance; no toxicity.

However, some unscrupulous traders use ordinary plastics to make them. Although the cost is very low and the price is very cheap, the damage is extremely fast, and it is not resistant to high temperature and corrosion. It is very likely to pollute your stirred liquid. , which has a great impact on your experiment.

The magnetic stirrer made by Beijing Zhongxing Weiye uses safe and non-polluting materials to ensure your experiment is perfect.
