PTFE Magnetic Stirrer Mixer, Akozon 5pcs Magnetic Stir Bar, Stir Plate Magnet Stick Type-C White Color PTFE Stir Bar Laboratory Stirrer Flea Lab Spinner for Magnetic Mixer (C7*30mm)

【Laboratory stir bar】The stir bar is used for mixing liquids or solutions in biological, chemical, medical and research laboratory applications to accelerate dissolution, promote mutual dissolution, and mix in evaporation dish to avoid splashing due to to uneven heating. Especially the most widely used in high school experiments, it is an indispensable experimental equipment. 【High and low temperature resistance】This magnetic mixer rotary stirring rod has high temperature resistance, the maximum working temperature can reach 250 ℃. It also has low temperature resistance, good mechanical toughness, and can maintain 5% elongation even at -196 ℃. 【Corrosion resistance】The Stir Plate Magnet Stick is PTFE coated, is chemically inert to most chemicals and solvents (such as strong acids, alkalis, water, and organic solvents). 【High lubrication】Magnetic stirrer stir bars have the lowest friction coefficient among solid materials, they can not only be used with corrosive chemicals, but also help reduce friction and wear during use. 【Non-sticky】These Flea Magnetic Mixer Spinners have the lowest surface tension among solid materials and do not adhere to any substance. Even if it is exposed to the atmosphere for a long time, the surface and performance will not be affected.
