4 Pcs 25mm(1 inch) 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 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

These are actually really good bars their magnets are definitely stronger than the ones I just got off eBay so they spin faster and stay on center better free one day shipping and cheap as dirt I'll never buy another as long as these are available
