7 Pcs type B Biological Stirring Bar Corrosion Resistant PTFE Mixer Spinbar Rod Practical Research Magnetic Laboratory Stirrer

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