Material: Polytetrafluoroethylene
Used to stir a liquid or solution in biological, chemical, and research laboratory applications.
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.
Stir bars are coated with PTFE covering, which is chemically inert.
Can be used with corrosive chemicals, also helps reduce friction and wear while spinning.
Individual shapes create different vortexes for efficient and effective stirring.
