Science folks, these LABALPHA magnetic stir bars are exactly what your lab needs! You get 6 of them in one package, each measuring 50mm long by 9mm diameter - perfect for most standard beakers and flasks. The PTFE coating is the real star here - this stuff is seriously chemical resistant, handling acids, alkalis, and pretty much anything you throw at it without reacting. The smooth surface reduces friction so they spin smoothly without jumping around, and the high-quality magnetic steel inside provides strong, consistent rotation. They're durable enough to handle high temperatures and serious rotational forces without wearing out. Whether you're in a university lab, industrial setting, or doing research work, these stir bars make mixing solutions so much easier and more consistent. The PTFE material means nothing sticks to them, and they're easy to clean between uses. No more worrying about contamination or inconsistent mixing - these deliver professional results every time. If you're tired of stir bars that lose their magnetism or get damaged by chemicals, this 6-pack gives you plenty of replacements and backups. Seriously, for anyone working with liquids that need thorough mixing, these magnetic stir bars are absolute lab essentials!
