The VWR SpinBar Magnetic Micro Stirring Bar, model number 58948-353, is a high-quality stirring tool designed for precise and efficient mixing in various laboratory applications. This set comes with eight stir bars, each measuring 8mm in length and 1.5mm in diameter, providing excellent coverage for your flasks or beakers.
The stir bars are made of stainless steel, ensuring durability and resistance to corrosion, even when used in harsh chemical environments. Their small size allows for use in narrow or shallow vessels where larger stirrers may not fit. The 1.5mm diameter ensures a fine-tuned stirring action, reducing the risk of splashing or spilling.
Each stir bar features a unique spinbar design, which consists of a series of small, closely spaced protrusions on the surface of the bar. This design increases the contact area between the stir bar and the liquid, resulting in improved mixing efficiency and reducing the time required for complete mixing.
The magnetic property of the spinbar allows for easy attachment and removal from magnetic stirrers, reducing the risk of accidental spills. The spinbars also have a smooth, polished finish, which minimizes particle entrapment, further enhancing mixing efficiency.
These VWR SpinBar Magnetic Micro Stirring Bars are an excellent choice for laboratory applications that require precise and efficient mixing, such as chemical reactions, heat transfer experiments, and biochemical reactions. Their durability and magnetic properties make them a reliable and convenient addition to any laboratory setup.
