Product: Magnetic stir bar / Stirrer B / Cylindrical magnetic stir bar / Magnet laboratory stirrer Key benefits — why you need this product - Reliable, uniform mixing: the cylindrical magnetic stir bar creates a rotating magnetic field that produces consistent, bubble-free stirring in flat-bottom containers, improving reproducibility in lab protocols. - Reduced vibration and wear: Lab stirrer B is precisely manufactured to minimize vibration and mechanical wear during continuous stirring and mixing operations. - Chemical compatibility and durability: resistant to acids, bases and a wide range of organic solvents; virtually insoluble in common solvents, so the stir bar remains stable and long‑lasting under typical laboratory conditions. Main functions and standout features - Function: designed for stirring liquids and solutions in biological, chemical and research laboratory applications. - Operation: place the cylindrical magnetic stir bar into a flat-bottom container; the external magnetic drive generates rotation to provide even mixing. - Construction quality: excellent workmanship reduces operational vibration and extends service life compared with lower-quality stir bars. - Chemical resistance: acid- and alkali-resistant and compatible with many organic solvents; suitable for routine lab solvents and reagents. Compatibility and practical attributes - Uses: suitable for general laboratory mixing tasks across biological, chemical and research environments. - Container type: optimized for flat-bottom beakers and flasks where a rotating magnetic field can couple efficiently to the stir bar. - Handling: compact and easy to place or remove; designed for convenient use with standard magnetic stir plates. - Performance: consistent, stable rotation for homogeneous mixing and reduced risk of sample disturbance. Typical applications (use scenarios) - Preparing reagent solutions and buffer mixes in chemical and biological labs where consistent homogenization is required. - Mixing reaction mixtures or solvent systems that include acids, bases or organic solvents, taking advantage of the stir bar’s chemical resistance. - Routine sample preparation and dilution steps in research workflows where low-vibration, long-term stirring improves reproducibility. What it solves - Eliminates uneven mixing and hot spots caused by inadequate agitation. - Reduces downtime and maintenance by minimizing vibration-related wear on the stir bar and stir plate. - Provides a chemically robust stirring element that withstands common laboratory reagents without degrading or contaminating samples.
