【Complete Stir Bar Set】Includes 5×10 mm, 6×15 mm, 6×20 mm, 7×25 mm, 7×30 mm, 8×30 mm, 8×35 mm, 9×28 mm magnetic stir bars plus 250 mm PTFE retriever—perfect for laboratory stirrers, magnetic mixers, or DIY projects.
【PTFE Coated for Chemical Resistance】All magnetic stir bars and the retriever are coated with PTFE, offering excellent corrosion resistance, low friction, and long-lasting performance for your magnetic stirrer.
【Efficient Design for Flat-Bottom Containers】Cylindrical stir bars with shaft rings provide stable rotation and optimal turbulence for thorough mixing. Ideal for low-viscosity liquids; stirring efficiency may decrease with thick or oil-like solutions.
【High Lubrication & Non-Stick】Magnetic stir sticks resist adhesion, feature minimal surface tension, and the lowest coefficient of friction among solid materials—ensuring smooth, efficient stirring.
【Wide application】Compatible with magnetic stirrers, hot plates, beakers, stir plates, and mycology setups ;fits most lab mixers.
