Magnetic Stirrer Stir Bar PTFE Magnetic Mixer Stir Bars (5X10mm, Olive Shape, 10pcs)

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.

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

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 would have given 5 stars if I'd have actually gotten the 5 bars I ordered not 3 they sent and one was unbalanced immediately 2nd I tried n it worked... for how long doubtful

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

Worked perfect for me in my 2l flask and worked at top speed.

I wanted a larger bar to stir a big cylinder. All three could not stay on the plate. They just spun onto their tip and then flew off the center.
