Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196 ¡æ, can also maintain a 5% elongation 8.No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance 9.Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged, there is B06B plastic in the best aging life 10.Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions

Review: Great product, zero issues - 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)
Review: Yes much better than stock stir bar - Big chonk size, super strong force, compatible with my LVDALAB 5L stirrer, good price for effectiveness, easier than hand mixing my hydroponic nutes.

### ⭐⭐⭐⭐⭐ Better than a Similar, Much More $, Stirrer
*by D***R on May 30, 2024*

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.
