Description
The Coated Magnetic Dumbbell – Star Shape is a specially designed magnetic stir bar that combines dumbbell-shaped ends with a star-shaped profile for maximum vortex formation and efficient mixing in laboratory solutions. Constructed with a strong magnetic core fully coated in PTFE (Teflon), it is resistant to chemicals and ideal for high-viscosity liquids, large volumes, and uneven vessels.
The unique dumbbell-star configuration ensures rapid and uniform mixing while minimizing stirring time, making it perfect for chemical, biological, pharmaceutical, and analytical laboratories.
