4 Pcs 10mm(0.4inch) Magnetic Stir Bar,PTFE,White

Excellent magnetic pellets. Great value for the money

I bought these little magnets to replace one I lost from one of those battery-run self-stirring mugs. Turns out the size is bigger than the original, so it stirs more vigorously, but it works.

I was using a pressure cooker at 15psi for 20 minutes to cook my LC mix and these magnetic stir bars handled the heat well. If you plan on doing the same, i recommend these. Perfect size for my half pint jars. I ended up buying some more.

I bought these to replace one that I managed to drop and wasn't able to find. I use them in a marine water test device to increase testing speed results. They're cheap - keep a few on standby.

Compact easy to use

These are slightly bigger than the one that came with my Auto Aqua smart stir I use for saltwater testing. great to have a few extras on hand as they are smaller than a TicTac and can be misplaced easily. I ordered the 10mm and very satisfied with their performance.

I lost the original that came with the stirring cup. This fit the cup perfectly. Works just like new again.

If you get a magnetic stirrer, be very careful placing the magnet back on the base for storage. If the poles are misaligned that little white pill will go flying. It took me 3 days to find it the first time it happened. The second time it happened I swear I was being careful, I looked for 2 days and decided it would be wise to have more the one stir bar and that's how I ended up here. Now, I'm not going to say these are the greatest stir bars of all time, but I still haven't found the one I lost, and I haven't lost one of these...yet
