Magnetic Stir Bars

Magnetic Stir Bars

A magnetic stir bar is a small, cylindrical or shaped rod with a smooth, typically white or transparent coating, depending on its material. Inside, it contains a magnet, which may be visible in transparent coatings like glass. Common coatings are PTFE (white and opaque) or glass (clear and shiny) with a variety of shapes.

Micro Stir Bars: Compact for use in small vessels, ideal for precise, small-scale reactions or delicate samples.

Plain Stir Bars: A plain stir bar is a cylindrical rod featuring a distinct ring around its center, creating additional turbulence to improve overall mixing efficiency

Cylindrical Stir Bars: A straightforward, rod-like bar with a uniform, smooth cylinder shape and rounded ends with no central ring or other added features; they are entirely smooth along their length

PTFE-Coated Stir Bars: Coated with polytetrafluoroethylene (PTFE), these stir bars offer exceptional chemical resistance and a non-stick surface, making them ideal for most laboratory applications, including acidic and basic environments.

Glass Coated Stir Bars: Used in applications requiring extreme chemical resistance, needed to withstand exposure to aggressive solvents.
