Answer:Each plain magnetic stirring bar is 40 mm long and 8 mm in diameter.
Answer:The package contains five PTFE-coated magnetic stirring bars.
Answer:No. The bars are passive mixing accessories driven by a separate magnetic-stirrer instrument.
VWR Plain Magnetic Stirring Bars are laboratory mixing accessories with a 40 mm length and 8 mm diameter, supplied in packs of five. Each stir bar combines a magnetic core with a smooth, chemically resistant PTFE covering for use in compatible vessels positioned on a magnetic stirrer. The simple cylindrical configuration supports mixing of aqueous reagents, buffers and many common laboratory solvents while minimizing direct contact between the liquid and the magnetic core. Choose a vessel with a sufficiently flat base and enough clearance for free rotation, then increase the stirring speed gradually to maintain a stable vortex without decoupling the bar. Inspect the PTFE surface for scratching, chips or contamination before use and replace damaged bars. The stirring bar is an accessory for a magnetic-stirrer instrument, not the powered stirring device itself.
