PTFE (polytetrafluoroethylene) Magnetic Mixer Stir Bars is a stirring tool used in laboratory magnetic stirrer. They are usually made of corrosion-resistant polytetrafluoroethylene, which is similar in structure to a gear. This design helps to create more eddy currents during the mixing process, which improves mixing efficiency. Gear shaped agitators are often used in experiments where higher stirring efficiency is required or where more viscous solutions are handled.
PTFE Magnetic Mixer Stir Bars Features:
Chemically inert: PTFE is a very stable material that does not react with most chemicals and therefore does not cause contamination or sample deterioration.
Temperature resistance: PTFE can withstand higher temperatures and can often be used in environments with temperatures up to 260°C (500°F).
Corrosion resistance: PTFE is very resistant to many corrosive chemicals, such as acids, bases and organic solvents.
Magnetic core: The mixer contains a magnetic core inside, which allows it to rotate under the action of a magnetic field, thus agitating the liquid in the container.
Efficient mixing: The design of the gear shape helps to create strong eddy currents in the liquid, which helps to mix the sample quickly and evenly.
When using PTFE Magnetic Mixer Stir Bars, the following points need to be noted:
Ensure that the mixing speed is moderate, so that the mixer does not jump out of the container due to high rotation speed.
Avoid using the stirrer for a long time without liquid to prevent overheating and damage.
Clean the mixer promptly after use to remove any chemicals that may stick.
Overall, the PTFE magnetic mixer gear shape is an efficient and versatile laboratory tool for a variety of mixing needs.
