## Features

- CORROSION RESISTANCE: The stir bar is made of a magnetic core and PTFE shell. It is corrosion resistant and has good chemical inertness. It can be used with most chemicals and solvents. (Such as strong acid, strong alkali, water and organic solvent)
- HIGH LUBRICATION: PTFE shell helps reduce friction and wear during spinning, the stir bar has the lowest friction coefficient in solid materials.
- EASY TO USE: The stir bars are non-sticky, they have the lowest surface tension in solid materials, and do not adhere to any substance. When they are used, they only need to be placed in a container filled with liquid, which is located on a magnetic stirrer.
- TEMPERATURE RESISTANCE: This stir bar is resistant to high temperature, the maximum working temperature can reach 250℃; it is also resistant to low temperature, has good mechanical toughness, and can maintain 5% elongation even at -196℃.
- WIDE USE: The stir bar is placed inside a container of liquid or solution that is seated on a magnetic stirrer, creating a rotating magnetic field using a rotating magnet or multiple stationary electromagnets. Widely used in biological, chemical, medical and research laboratory applications.
