The Physics of the “Dancing” Stir Bar: Solving Mixing Failures in Heterogeneous Synthesis
Stir bar decoupling is more than a mechanical glitch—it’s a failure of mass transfer that ruins yields. In this technical deep dive, we move beyond the “standard” round bottom flask to explore why flat-bottomed geometry is essential for solid-heavy reactions. From the physics of point contact to the advantages of crosshead stirrers, learn how to stabilize your synthesis and protect your glassware from thermal stress.
