Pivot PTFE Coated NeFeB Magnetic Stir Bar 100mm 4Inches Pack of 4

Unleash the full potential of your laboratory work with our premium PTFE-Coated Neodymium Magnetic Stir Bars. Engineered for the professional scientist and passionate hobbyist alike, these stir bars are the cornerstone of efficient, reliable, and contamination-free mixing. Crafted with a powerful core of neodymium—the strongest permanent magnet material available—our stir bars deliver vigorous and consistent vortexing even in high-viscosity solutions. Whether you're dissolving solids, mixing reagents, or performing heating tasks on a hot plate stirrer, they provide the unwavering performance required for reproducible results. Your research integrity is our priority. Each stir bar is seamlessly encapsulated in a high-purity, chemically inert Polytetrafluoroethylene (PTFE) coating. This superior shield offers maximum resistance to a vast array of aggressive chemicals, acids, and solvents, ensuring your samples remain pure and uncontaminated. The non-stick, smooth surface makes cleaning an effortless task. Durability is built-in. The rugged, one-piece PTFE construction is thermally stable and protects the magnet from corrosion, chipping, and cracking, significantly extending its lifespan. The polished finish ensures scratch-free operation, safeguarding your valuable glassware from damage.

• SUPERIOR MAGNETIC STRENGTH: Features a powerful Neodymium (NdFeB) core that ensures strong rotational coupling, high-speed stirring, and consistent performance without decoupling.
• EXCEPTIONAL CHEMICAL RESISTANCE: The seamless, PTFE coating is impervious to most chemicals, protecting both your experiments and the stir bar itself.
• SCRATCH-FREE & NON-CONTAMINATING: The smooth, polished surface glides smoothly across the bottom of beakers, flasks, and vessels, preventing scratches. The working temperature can reach up to 120 ℃ (248 Fahrenheit).
• THERMAL STABILITY & DURABILITY: Operates effectively across a wide temperature range and is built to withstand demanding lab environments. The one-piece design prevents fluid ingress and breakage.
• EFFORTLESS CLEANING & MAINTENANCE: The non-stick PTFE surface allows for quick and easy cleaning, often requiring just a rinse.
