Magnetic Stirrer Stir Bar Big 2.8 inch Length PTFE Magnetic Mixer Stir Bars,1 Piece

They work as intended and are an excellent price. I'm very satisfied with this purchase.

These fit perfectly into the 5ml bottles I purchased and work great with the mini-table as well. Working great for my aquarium chemistry checks.

I use this to blend very thick (like mayo at blending temps of 125f) mixtures on a magnetic stir plate, it works well when the flat side lies on the bottom of the beaker. The size and weight are very good, but the outer sheathing could be a bit stronger

I've only had to purchase this item once because of how reliable the product is. I can't say they're the best stir bar money can buy, but for the price it's definitely worth it. These stir bars have yet to lose their magnetism! My biggest problem with stir bars was always how long they stayed magnetic, these were the solution. HIGHLY recommended!

I ended up getting a pack of standard bar type stir bars, not olive shaped ones.

They work great and the price was very reasonable.

People, including myself, just quickly brouse the photos and description to help them make the purchace within 3 to 5 seconds. This is add/item is totally misleading showing 3 bars in the main photo, stating Bars in the description and 1 in the quantiy but not 1 quantity = 1 bar not 3 bars.I've read that I am not the first person to be shocked with the lack of bars when delivered..

These are a bit small for 1.5 pint wide mouth jars, they will work but you need to use high speed. does not work with more than one with my equipment, not sure the magnet strength is high enough to work in groups of 2 or 3
