Magnetic stir bars sorptive extraction before a new sample preparation techniques, we introduced a unique commercialization stir bar, coated with adsorbent coating thereon; A magnet bars into the sample stirring period of time, so that the components to be analyzed to achieve a balance in the distribution of the sample matrix and the adsorption layers. The principle is similar to the solid phase micro-extraction.
PTFE magnetic stir bar magnet or permanent magnet high refined, with wear-resistant, high temperature resistance, chemical corrosion, rotary torque, stable, fine workmanship, innovative style, scientific and aesthetic advantages. Supporting all types of magnetic stirrer. Widely used in petroleum, pharmaceuticals, chemical and biological laboratories, teaching and research, analysis room for the stirred solution.
