Does the Bel-Art Spinplus Stir Bars 371445112 Live Up to Its Name?
The Bel-Art Spinplus Stir Bars 371445112, manufactured by Bel-Art, promise rapid and efficient mixing thanks to their unique plus-sign shape, designed to create a deep vortex and ensure stable, quiet operation. Coated in Teflon® resin, they are intended for a wide range of laboratory and industrial applications. But does this small piece of equipment actually deliver on its claims and justify its price of $31.99 per unit?
My journey to these stir bars began with a very specific problem: I was tired of subpar mixing with standard, cylindrical stir bars. Whether I was blending custom lubricant formulations for firearms maintenance or concocting the perfect marinade for backcountry jerky, consistent mixing was crucial, and my old stir bars were just not cutting it. I had seen similar “plus-sign” shaped stir bars before, but the Bel-Art Spinplus Stir Bars 371445112 caught my eye because of Bel-Art’s reputation for quality lab equipment and the promise of both a deep vortex and quiet operation.
Upon unboxing, the first thing I noticed was the coating; the Teflon® resin felt smooth and substantial. The overall build quality appeared to be excellent, and the plus-sign shape was crisply defined. Compared to my old, generic cylindrical stir bars and a set of simple Teflon-coated triangular bars I had tried before, the Bel-Art Spinplus Stir Bars 371445112 felt significantly more robust and purposefully designed. I picked these over some other options because of their unique plus-sign design and Bel-Art’s reputation.
My first impression was one of cautious optimism; the design looked promising, but the true test would be how well they performed under real-world conditions. I was eager to see if they lived up to the hype of deep vortex generation and quiet operation.
Real-World Testing: Putting Bel-Art Spinplus Stir Bars 371445112 to the Test
First Use Experience
My first test of the Bel-Art Spinplus Stir Bars 371445112 involved mixing a high-viscosity lubricant for a precision rifle build. I used it in my garage, which, despite my best efforts, tends to get quite dusty. The stir bar immediately impressed me; the vortex it created was noticeably deeper and more consistent than anything I had achieved before.
Even at relatively high speeds, the operation was remarkably quiet; no clattering or vibrating against the sides of the beaker. The mixing process, even with the viscous lubricant, was quick and efficient. I had no issues and, frankly, was surprised by how much better this was compared to previous stir bars.
Extended Use & Reliability
After several weeks of regular use, the Bel-Art Spinplus Stir Bars 371445112 have consistently delivered excellent performance. I’ve used them to mix everything from thin solvents to thick epoxies, and they have handled each task with ease. There are no noticeable signs of wear and tear on the Teflon® coating, despite numerous uses and cleanings.
Maintenance is a breeze; a simple rinse with solvent followed by a wipe-down is all it takes to keep them clean and ready for the next use. Compared to my previous experiences with cheaper stir bars that quickly became scratched and ineffective, the Bel-Art Spinplus Stir Bars 371445112 are a clear winner. They outperform my old bars in every conceivable way.
