Magnetic Stirrer Stir Bars (15X35 mm, Olive Shape,5 PCS)

Why did you pick this product vs others?: great when you have a lot of sediment to stir in your extraction that causes typical stir bars to become over encumbered and pause, no longer stirring. Soap nuts, arnica, ashwaghanda even zinc oxide is no challenge for these stir bars, provided you have the right amount of transport medium/solvent (Water, alcohol or oil)

Big chonk size, super strong force, compatible with my LVDALAB 5L stirrer, good price for effectiveness, easier than hand mixing my hydroponic nutes.

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.

Great item but there is a disparity between the image listing 3 items and the official documentation listing one item. It’s a 5 star item but I’m giving 3 until the picture lists only one item.

good quality

These are extra "pills" for my magnetic stirrer, Perfect for my needs, I use them to vortex oxygen into my drinking water, also I use them for stirring my coffee, I use powdered milk and a tablespoon of honey, and these are the perfect size for a coffee cup, ads oxygen to my coffee also! Water Vortex machines can cost hundreds of dollars, but these magnetic stirrers are cheap and do exactly the Same thing!!!

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.

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
