- Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt
- Casing material is approved for use in food, drug, and cosmetic applications

### ⭐⭐⭐⭐⭐ 







  
  
    Why do they even make flat stir bars?
  

*by J***R on Reviewed in the United States on August 5, 2014*

I use this when I'm making yeast starters for home brewing, which doesn't really require any crazy speeds on my stir plate - just enough to make a vortex.  Even then, most of the time my traditional stir bars would get thrown so very easy. Nothing worse than waking up in the morning to find that your starter (probably) hasn't been spinning all night.With this one, I almost never have to worry about it getting thrown. Once it's lined up and spinning, it's rock solid. As a bonus, I don't need as much speed to create a vortex either. It's the only stir bar I use any more. Seriously, why are you still reading? Buy this one, it's awesome!

### ⭐⭐⭐⭐ 







  
  
    Works well.  Expensive.  Not amazing.
  

*by A***G on Reviewed in the United States on June 13, 2014*

I use this for making yeast starters while homebrewing.  I own a professional-grade stir plate, and both 1000ml and 2000ml erlenmeyer flasks.  The bar spins fairly well and produces a decent vortex; anecdotally, it may be a stronger vortex than a regular stir bar.  However, unlike a flat stir bar of similar length, however, this one appears to be more prone to "throwing" at high speeds.  I was able to get it to operate sufficiently at about 75-80% of the stir plate's maximum setting.

### ⭐⭐⭐⭐⭐ 







  
  
    Tracks better & produces a better vortex
  

*by V***. on Reviewed in the United States on March 18, 2014*

I'm comparing this unit with the Bel-Art Octagonal Spinbar, and another magnet that was very similar to the Spinbar that came with my magnetic stirrer.  In water this Cross produces the best vortex.  For my application, I'm stirring a very thick fluid, and this unit tracks my magnetic stirrer machine better than the other two.  I have purchased 3 more of these, because they work the best in my application.
