Features: The magnetic stirring rod can resist high temperature, corrosion, abrasion and high rotation force. It has fine workmanship, no impurities and burrs on the surface, stable speed and no deviation High-quality material: PTFE magnetic stirrer is made of PTFE and high-quality magnetic steel. The cylindrical and smooth surface can reduce friction and improve smooth rotation. Other applications: Laboratory strips are widely used in scientific research, universities, industrial and agricultural laboratories, and can also be used to stir mixtures. Widely applicable: the stirring plate magnet bar can be used in conjunction with various types of magnetic stirrers or heating stirrers Colour: white Material: PTFE Package Contents: 8 x Stir bar(C6*10 to C8*40) Only the above package content, other products are not included.
