(Set of 3) Magnetic Stirrer Stir Bar PTFE Magnetic Mixer Stir Bars Gear Shape

1. Size:40x7mm ( diameter x length) 2. Shape: Eight gear type ; Quantity: 3 pcs 3. Strong Magnetic, New & Clean & Cute 4. High temperature: the use of operating temperature up to 250 ℃ 5. Corrosion resistance: for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents 6. High lubrication: the lowest coefficient of friction in solid materials 7. Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196 ℃, can also maintain a 5% elongation 8. No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance 9. Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged, there is B06B plastic in the best aging life 10. Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions
