ANZESER Magnetic Stirrer Hot Plate w/Stir Bar,100-2000rpm Magnetic Hotplate Stirrer, 180W Heating Power Hot Plate Stirrer, Max 520℉ Hot Plate with Magnetic Stirrer

Received and tested. All works as described. Heat pad did not make it to 500 degrees but did go 488 which is no big deal to me. With a non-viscous liquid such as water the spinner does not go slow enough to prevent cavitation. I can turn it down all the way and a fraction more it cuts off. But at the lowest point prior to cut off it spins fast enough to pull in an occasional micro bubble. I don't think this would happen once I added a foreign material but would be nice if it had a little mor control at low speed.

This is the best and user friendly magnetic stirrer hot plate ever existed. It is less heavy and easy to use for different projects. The product comes with a portable support stand that you can use to perform titration and droplet mixing of two different chemical solutions. Absolutely, useful for micro/nanoencapsulation application. I have used it to prepare enzyme micro-encapsulation beads for a mini project, and the result was successful. I will definitely recommend anyone to buy this product as it is cheaper and value for money.

Well constructed, clean, no BS, cheap, sturdy little unit. And the magnetic stir feature is well tuned and works well, which is something I was worried about. My only complaint is the heat, it's not very powerful at all. So much so that I doubt it's hitting the claimed wattage output. I've had 300-200mL of tap water in a 500mL Erlenmeyer flask on this for about the last hour or two with very light stirring and full heat and I'm only barely getting to boiling. It's certainly not a powerful, rolling, foaming, kind of boil though. Outlet can run a 1500w space heater without problems, so it's gotta be this things heat element. So, it's maybe good for extremely small volumes, low power organic synth, or getting organic solvents boiling. I could see this being AWESOME for reactions that need a constant, low heat for ages. But it's not great for anything more power demanding. You're certainly not going to dehydrate sulfuric acid or distill mercury with this. I may return, then again, I may try and remove some length of the heater wire to up power. I could also set it aside for the above mentioned reasons, since it would be the perfect tool for that purpose.

It arrived, packaged well. I tested it with a 500 ml beaker full of cold water, with the stirring on about halfway, and slowly increased the temperature over time. The heating and stirring work well. The attaching arm could be a bit better, but for the price and getting the job done, it's a great item.

Impossible to control heat. I needed a range of 60c-80c after fighting with it for 2 hours I gave up. As soon as it's on it goes from cold to 120c with no control at all. The stirrer goes from off to extreme speed with no way to slow it down. Worthless device should not be for sale. Awful. I will return.

It was a Christmas gift for my son. He was very pleased with it. Not sure how he plans to use it, he is an electrical engineer. I was impressed with how secure it was packaged to prevent breakage.

Love this hot plate/stirrer! It stirs and heats, which I use all the time for science demos in my classroom. And the price is well within my budget—much cheaper than what I could get in a science classroom supply catalog!

I bought this for my hobbies needs and was surprised how well it works. It gets quite hot and can make awesome hot chocolate for the grandkids. They enjoy doing science projects with grandpa. Next, I plan to take over the world! "Insert evil laughter here. . ."

Fait très bien le travail pour un laboratoire comme le nôtre qui n'a besoin de l'utiliser que 2 fois par semaine

Fantastic, high quality product , still going approx 1 year on daily use.

温めながら攪拌出来て便利に使用しています。 ヒーターは温まるまで多少時間がかかります。 ある範囲内に温度調整したい時はコツが必要です。

Although delivery was a day later am happy with the content and customer service second to none.

Ottimo prodotto con un rapporto prezzo/qualità imbattibile: consigliatissimo.
