This olive-shaped stirrer is designed for mixing and stirring applications in demanding chemical, pharmaceutical, food, and metallurgical environments. Fabricated from high-purity polytetrafluoroethylene (PTFE), it offers excellent chemical inertness, resisting strong acids, alkalis, and most organic solvents, along with a low coefficient of friction and non-adhesive surface. The PTFE shell retains good mechanical toughness at low temperatures, maintaining about 5% elongation. Each stir bar contains a permanent magnet for standard magnetic stirring; however, prolonged use at or above 200°C should be avoided to prevent demagnetization. Available in multiple sizes from 3×6 mm to 12×25 mm, this stirrer provides reliable performance for routine laboratory mixing tasks where corrosion resistance and low friction are required.

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.
