This PTFE magnetic stir bar features an oval body with a maximum diameter of 18 mm at the center, gradually tapering toward both ends for smooth and stable rotation. With a length of 60 mm, it is ideal for larger laboratory vessels and ensures efficient mixing even at higher stirring speeds. The PTFE coating provides excellent chemical resistance and reliable performance across extreme temperatures ranging from –200 °C to 260 °C.
