FAQ's of Triangular Magnetic Stirrer Bar, PTFE / ALNICO V MAGNET:
Q: How is the Triangular Magnetic Stirrer Bar used in laboratory settings?
A: The stirrer bar is placed inside a vessel containing liquid, and a magnetic stir plate beneath the vessel generates a rotating magnetic field. The strong Alnico V magnet core allows the bar to spin efficiently, mixing the liquid thoroughly.
Q: What advantages does the PTFE coating offer for this magnetic stirrer bar?
A: PTFE coating provides strong chemical resistance to acids, bases, and solvents, making the bar suitable for use with a wide array of substances. Additionally, it delivers a smooth, non-stick surface that is easy to clean and prevents unwanted reactions with samples.
Q: When should I choose a triangular magnetic stirrer bar over other shapes?
A: A triangular stirrer bar is recommended when enhanced turbulence and mixing efficiency are important, especially for rapidly dissolving solids or ensuring homogeneity in dense solutions. Its shape helps achieve more effective fluid circulation compared to traditional cylindrical bars.
Q: Where can this magnetic stirrer bar be sterilized, and is it reusable?
A: The bar is autoclavable, which means it can be sterilized in a standard laboratory autoclave. Its robust construction allows for repeated sterilization and reuse, maintaining reliable performance over time.
Q: What laboratory vessels and capacities are compatible with this stirrer bar?
A: This magnetic stirrer bar comes in various lengths (commonly 20-40 mm), making it suitable for a wide range of vessel sizes, from small flasks and beakers to larger laboratory containers, supporting versatile laboratory applications.
Q: How does the temperature and speed resistance of this stirrer bar enhance laboratory mixing?
A: With resistance to temperatures up to 250C and a wide operative speed range (typically 100-1500 RPM), the stirrer bar performs reliably in both gentle and vigorous mixing conditions, accommodating processes that involve heating or require rapid agitation.
Q: What makes this magnetic stir bar safe and environmentally friendly for laboratory use?
A: Manufactured from non-toxic, chemically inert materials, the stir bar does not leach hazardous substances into solutions. Its durability and ease of cleaning allow for repeated safe use, reducing waste and supporting sustainable laboratory practices.
