I purchased this pack of stir bars for my resin setup, and they have been excellent. The coating ensures that the bars are chemical resistant and easy to clean, which is essential when working with different types of solutions. The diff. sizes are perfect for mixing in various containers, and the magnetic strength is just right for efficient stirring. I've used them in both hot and cold liquids without any issues. These stir bars have improved the consistency of my resins (air bubbles and thicker coloring) A must-have for anyone in need of reliable and durable stir bars!

AnyLab Stirrer arrived quickly, well packaged and I found it to be of very good quality. It came with four diffent sized magnetic stirring "pills" and I held the longest one in my fist and brought it close to the stirrer base to test the strength of the unit. The base turns on with a solid "Click" and the speed adjustment is smooth and firm. At just "ON", the pill had no motion, but it was definitely attracted to the rotator under the base table surface As I increased the speed adjustment knob the "Pill" in my hand tried to stay in sync with the drive magnet and it vibrated strongly in my hand, even an inch above the table. Definitely a very effective stirrer that will probably do quite well, even with thick or viscous fluids. I'm going to use it to mix some vinaigrette dressing instead of shaking it. I'll also try it to mix some flavor syrup (liquor) into my coffee. Lab work? Yes, it'll do that too. The manual says it takes only 3 watts, but seems stronger than that. Overall rating: Great!!! Mine even came with a nice long Magnetic Pill Retriever.

I got these to make mushroom slants for long term culture storage, and they work pretty darn well for that. They are autoclavable, which means that I can sterilize them in my pressure cooker, which makes them essentially endlessly reusable (yeah eventually they will break down, but that will take a *long* time). The cost of these comes to $0.60 each, before taxes (less then $0.66 each with WA state taxes) so they are a reasonably cost effective option, a bit cheaper then some of the others I have gotten from Amazon.

They work well for my purposes, YMMV if you are actually centrifuging them.

I bouth this magnetic stirrir primary usage for cocktails bar. it strong enough to mix sugar and cold water just fine without making a noise. it comes with the stirrir and magnetic wand as well.
Overall is very good. I'd recommed to buy it

I use this everyday to mix my powder supplements into my tea. Honestly, one of my best purchases. My tea is mixed smoothly with no lumps and everything is easy to clean.

I worked in a pharma lab for decades and we had thousands of stirbars all stuck together in a drawer. It is nice to see them separated in a display case for all the work they do!
