Magnetic Stirrer Stainless Steel Magnetic Mixer with stir bar (No Heating) Max Stirring Capacity: 3000ml

Update: After playing around with different sized stir bars I found that 25mm works better than 30mm for a standard mason jar as well as various flasks and media bottles. Either the standard cylindrical or type B with a center spin ring work well. The shorter stir bar appears to mix solutions just as well as the longer, but able to obtain faster rpm with fewer spin outs. Maybe the unit comes with a 25mm bar for a reason. Duh! I can’t attest to the magnet strength, but it works well enough for me to upgrade to 5 stars. It seems that everybody working with liquid cultures owns at least one of these. For $20 it’s hard to find a basic stir plate with better reviews. That said, my experience is mixed. The price is right, sure, but the magnets are weak. Trying to get a standard 30mm stir bar centered and spinning in a quart size Mason jar is a challenge. The bar tends to get thrown to the side and stuck in the ditch perimeter of the slightly convex interior center. If the speed is ramped up too much it’s thrown off center and back into the ditch. Once centered and spinning at a low to moderate speed, it works well enough. I plan to try stir bars with a center spin ring to see if that helps. Compared to my Lab House hot/stir plate this is far inferior. Granted the other cost 3X more. I’d give it 2-3 stars based on performance alone, but for $20 I’ll be generous with 4 stars. YMMV

This mixer is great and a great value. I use it to mix ink, paint, and other mediums, and it does the job perfectly, even on relatively large containers with thick consistencies. It only comes with one stir bar. So, you may need to purchase more. I also suggest getting a powerful magnet to retrieve the bars from your containers to avoid messes.

Great for stirring powdered drink mixes

This magnetic stirrer works very well for the price. It spins smoothly, holds a consistent speed, and does exactly what it’s supposed to do for basic lab or hobbyist use. The stainless steel top is easy to clean and feels durable enough for regular use. My two small downsides are the power cord length and the included accessories. The cord is a bit short, which limits placement unless you’re close to an outlet or using an extension cord. It also only came with one magnetic stir bar. It works fine, but it would have been nice to have an extra included in case one gets lost or for using different container sizes. Overall, this is a solid, budget-friendly magnetic stirrer that performs well. If the cord were longer and it included an extra stir bar, it would easily be a 5-star product. Please keep in mind. This is not heated either. So for the price and being not heated, it still is a very good bye very easy to use and not very noisy

Works fine

This thing is phenominal! No more slinging paint, stain, and finish everywhere using a paint stirrer in a drill. My experience to date has been with wipe-on poly finish. I haven't tried it with one-coat paint which may be too thick. I also have not tried it with a metal can. I expect that NOT to work. The thing depends on a rotating magnetic field which metal would difuse to the point that I can't imagine it working. I just save all my used plasic containers to put liquids in to be stirred by this stirrer

Fantastic for mixing formula

Purchased this product in March of 2025. It is used twice per day to stir solution in a 500ml beaker while titration is occurring. Stopped working correctly on December 8, 2025. Motor turns as soon as power is applied (speed control pot is not working), but magnetic stirring pill does not rotate (it just bounces in same spot).

Muy útil y práctica por el tamaño. Funciona adecuadamente.

If you buy one and the little magnet just lays there and just vibrates, turn the unit off; the magnet will center itself, then turn it on and slowly increase the power. this is good for vary vary light mixing, any solid matter that hits it will knock the magnet off it's spin and it will go back to just vibrating

Good

I'm sure the Stirrer does the job, but can't if it only has a US plug on the power adapter. What's the point of selling items like this in the UK if it doesn't have a UK plug. Buyer be warned.

Todo al 100, del estado del empaque y del producto, del producto en sí, del servicio rápido y a la puerta de tu casa. Muy recomendable hasta que funciona perfecto, buen compromiso precio y calidad.
