SP Bel-Art Spinbar Teflon Elliptical (Egg-Shaped) Magnetic Stirring Bar; 63.5 x 19mm, White (F37130-0212)

After trying to be thrifty by buying inferior stir bars and sanding them down to 'improve' their stirring capabilities, I finally just decided to spend twice as much and try these.I was not disappointed. Make sure you get the right size!Thomas

Just what I needed for mixing viscous phytocomplex

I ordered the 1-5/8 x 3/4" (41.3 x 19mm) stir bar, which according to the Bel-Art's chart is the ideal size for RBFs between 500 and 1000mL. I have been unable to insert this stir bar into 24/40-jointed RBFs from several different manufacturers with volumes of 500 and 1000 mL.

decent stir bar. wish I would've gotten one that was 10x larger.

This is a teflon stir bar. It works very well for what I purchased it for. Thanks for a good product.

I bought it only for a present so I'm no help
