Customer Reviews for VEVOR Electric Overhead Stirrer Mixer 0-3000 RPM Overhead Stirrer Mixer 100W Overhead Stirrer 0-120 Minutes for Lab Mechanical Mixer

Good quality. Easily assembled. Highly adjustable. I would have liked a better stirrer but a decent replacement was not that hard to find.

For the price, this is good to start out with. I wish it came with a better clasp to hold the beaker in place. So I just ordered a chain from Amazon. It mixes well. Sometimes it takes a little maneuvering to get the mixer at the right height. But overall, it’s worth it for the cost.

This product was bought to supply mixing muscle over and above my magnetic stirring units. It has satisfied my needs.

This is a great piece of lab equipment for the price. Sturdy and not terribly difficult to assemble and navigate how to use. Instructions aren’t very helpful for assembly but with some common sense it’s not hard to figure out. The clamp that holds the beaker is not of high quality and the wing nut gets stuck when trying to adjust the width but I’d still rate this a 5 - for the price you’re getting a sturdy and effective piece of lab equipment and it’s been a great addition to my small scale lab to add efficiency and more consistent batch results.

I have been using magnetic stirrers to mix relatively viscous liquids and it has been problematic. The coupling with between the stirring bar and the motorized base is never strong enough to get the job done at high rotational speed -- the bar comes uncoupled and rattles about ineffectually. A simple immersion stirrer is the way to go. I used to have a Lightnin stirrer that was nice, but it eventually stopped working properly. Most of the immersion stirrers I considered as replacements were relatively expensive -- several hundred dollars. The Vevor immersion stirrer is an anomaly. It is dramatically less expensive, yet it works about as well as my old Lightnin stirrer. It doesn't have the digital rpm readout or the stirring power readout, but at about $60, I don't care. It does the job: it stirrer even quite viscous liquids over a range of speeds from very slow to faster than you can use. There is no decoupling to worry about and I like that it has both timed and on/off modes. If I had room, I'd buy more.

The product was a bit oily and makes a view uncertain noises when you first use it and install it. However, after cleaning and sterilization, it works fairly well especially for emulsions. I like that it came with two homogenizer heads. - JF

Love this homogenizer. It blends my beauty products well and fits up to a 1 L beaker with little splash. Great return on investment!

I have a few heating mantels and now this stirrer from mophorn. This stirrer is great and customer service helped me when I had an issue and immediately fixed it and now my stirrer works so good. I believe Vinson was the person who helped polite prompt and excellent person! This experience has influenced me to buy another heating mantel so go with this brand!
