Details
Shape: Olive-shaped
Material: Polytetrafluoroethylene (PTFE)
Features:
1. High temperature and corrosion resistance: Inert to most chemicals and solvents, resistant to strong acids, alkalis, water, and various organic solvents.
2. High lubricity: Low coefficient of friction.
3. Low temperature resistance: Good mechanical toughness; maintains 5% elongation even at low temperatures.
4. Non-adhesive: Low surface tension; does not adhere to other substances.
Applications: Widely used in chemical, pharmaceutical, food, and metallurgical industries for mixing and stirring liquids or powders.
Precautions: The stir bar has a PTFE shell and contains a permanent magnet, suitable for most conventional stirring needs. However, it should not be used for extended periods at high temperatures (200°C and above) to prevent demagnetization.
