Can stir bar put in microwave oven?

Couple days before, my college ask me "Can I put stir bar in microwave?". Work in the lab, we use stir bar all the time. We also use microwave to heat up a lot of material. Since my first day in the lab, almost every one know that don't put metal in microwave. So go back to the question Can I put stir bar in microwave? I will say "yes", but you can't put regular stirring in microwave. If you check the product menu, there is no description about this. Thanks for the Internet and email. After I did a little search. You do can put stir bar in microwave. There are some lab did this in their protocol for years. I also wrote to company to ask this question. They knew some lab do put stir bar in microwave, but they are not recommend me to use. This is the answer came from.
