🔧 Efficient Mixing and Stirring with Magnetic Stirrer Mixer Spinbar Stirring Review

I've used them many times and sometimes they get very magnetic before using them in a reaction and then after of the reaction I can't get them even if you use neodymium magnets outdoors. It seems that heating to around 200C or higher for a few hours will demagnetize them to some extent.

noticeable value when using very small cups for your purposes. Personally, I've only really used the large ones, but if I wanted to stir a tiny glass, it's a good deal for the price. Otherwise, if you're using 250ml or more, maybe just stick with packs of bars that are the same size on the larger side, as I don't think I'll ever use the smallest ones.

They work great with my magnetic stirrer/hotplate so far with no problems. I didn't realize how tiny the smallest ones were and don't know if I'll ever find a use for them to be honest as the smallest ones are about the size of rice chips. but they come in a nice cardboard box with foam cut outs for storage. They also double as boiling pearls lol. Can't complain for $10 as they do what they say and I had no problems.
