FAQ:
Q1. What is an oval magnetic stir bar used for?
It is used for stirring liquids on magnetic stirrers, offering stable mixing due to its oval design.
Q2. Is it chemical resistant?
Yes, the PTFE coating makes it highly resistant to most acids, alkalis, and chemicals.
Q3. Can I use it on a hot plate stirrer?
Yes, within safe PTFE temperature limits.
Q4. Is oval shape better than cylindrical?
Oval stir bars are often more stable and reduce “jumping” during high-speed stirring.
Q5. How do I choose the size?
Choose based on beaker/flask size and volume. Larger volumes require longer stir bars.
