Features:

1.Quantity: 7 PCS stir bars of different sizes and shapes + 1 PC recycling rod
2.Material: PTFE (Polytetrafluoroethylene)
3. Magnetic retrieverSize: 10'' ( 10mm in Diameter * 250mm in length)
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
