Magnetic Stirrer Stir Bar PTFE Magnetic Mixer Stir Bars (12X35mm, Olive Shape, 10pcs)

I bought the Cole-Parmer 37130-9003 Egg-Shaped Stir Bar, 3" L x 3/4" Dia; 1/Pk in April for $43.83. And it has worked well. But when I couldn't find it last week (since found), I ordered this very similar stir bar.Hands down, this iitem performs better. It's heavier, bigger, and thus mixes more. This magnet is significantly stronger. It will move itself to the magnetic center above the magnetic stirrer if the I place it anywhere close to that location. Also, this stir bar can handle a significantly faster rate of rotation per minute without spinning out. I got it up to 400 RPM, mixing lye into 4L of water, and had no interest in going any faster. I am assuming this stir bar will last for a good while, given the material of its composition. I will report back if any problems arise in that regard.At the moment, I am tickled pink.Update: This stirrer is also significany quieter than other stir bars I have used. Once it gets up to speed, I have to look at the surface of the liquid being stirrer to verify that it is being stirred.I received no compensation or benefit for this review.

I got this because it’s almost the exact same size as the one for the Corning PC-611 and it seems to work perfectly. It’s a fraction of the cost too!

Works great!

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

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

I should have read the description closer but be aware this is only for one unit and not three. Overall pretty nice and good quality but pricey for one piece.

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'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!
